The rural domestic sewage referred to the polluted water produced by rural residents in their daily lives, mainly including toilet sewage, kitchen sewage, bathing sewage, and livestock sewage. The main characteristics of rural domestic sewage are high dispersion and difficult to collect uniformly; small amount of water, but large fluctuation of water, with obvious seasonal changes; high concentration of organic matter, but no harmful substances; water quality and water volume vary greatly in different regions. The problems of rural domestic sewage treatment included imperfect governance mechanism, lack of focus on governance, unreasonable evaluation of governance effectiveness, and unscientific governance model. In recent years, China has taken a series of measures to promote rural domestic sewage treatment, but it still faces challenges in terms of standards, technology, funding, and mechanisms.

There were many reasons for the overflow of sewage. The following were some of the possible reasons: 1. Failure of the sewage treatment facilities of the enterprise: The failure of the sewage treatment facilities of a paper factory caused the sewage to not be treated, and the sewage flowed into the nearby water body. 2. [Sewer blockage: The sewers of a certain residential area are blocked by oil, causing the sewage to not be discharged normally and flow into the residential area.] 3. [Blocked sewage pipe: The sewage pipe of a certain residential area is blocked, causing sewage to leak from the floor to other floors or corridors.] 4. Septic tank and drainage pipe facilities are old: The facilities of the manure tank and drainage pipe in the old community are old, and it is easy to cause blockage and sewage crossflow. 5. Waste water overflow in car wash shops: When some car wash shops wash cars outdoors, the sewage will flow onto the sidewalk, affecting pedestrians. It should be noted that the above are only some possible reasons. The specific situation may vary according to the region and environment.

There were many ways to solve the problem of sewage overflow. First of all, the problem could be solved by optimization of sewage channels. The drainage of rural courtyards was usually done by digging ditches or connecting water pipes, but the drainage was small and easy to evaporate by the sun. With the popularity of tap water, sewage channels needed to be continuously optimized. In areas with scattered residences, sewage was usually treated by methods such as manure tanks, marsh gas tanks, and constructed grasslands. Secondly, the rainwater and sewage facilities could be modified to divert the sewage into the sewage pipe network. For example, by building a drainage ditch to divert sewage into the sewage pipe network, the problem of cross-flow of sewage was solved. In addition, it could also improve the sewage treatment measures and improve the sewage treatment capacity of the urban area. For example, building a sewage treatment plant to reduce the discharge of sewage. In short, the problem of cross-flow of sewage could be effectively solved by optimization of sewage channels, transformation of rainwater and sewage facilities, and improvement of sewage treatment measures.

The rural sewage interception pipe referred to the work of sewage treatment in rural areas. Through the laying of pipe networks and the construction of terminal facilities, rural domestic sewage was collected and discharged after treatment to prevent sewage from being directly discharged into nearby rivers and lakes and reduce water pollution. The purpose of this work was to achieve unified treatment of sewage, improve the efficiency of sewage treatment, and alleviate the existing water pollution situation. According to the information provided, some areas had already achieved full coverage of rural sewage interception and management. Through the construction of terminal facilities and pipe networks, sewage was treated and discharged. These terminal facilities had undergone standardized operation and maintenance to effectively treat sewage and meet the corresponding discharge standards. In addition, some areas could ease the pressure on the pipeline during the period of intensive sewage discharge by building sewage diversion facilities, further improving the efficiency of sewage treatment. In general, the implementation of rural sewage interception and management could effectively improve the water quality in rural areas and improve the quality of life of the people.

The municipal sewage interception pipe was a water pollution treatment project. By constructing and transforming the sewage pipeline inside the sewage generating unit and connecting it to the sewage pipeline system under the town road, the sewage was finally transported to the sewage treatment plant for central treatment. This project played an important role in urban sewage treatment. The goal of the sewage interception project was to intercept and concentrate sewage to reduce pollution to rivers and water bodies. In order to achieve this goal, it was necessary to dismantle the original sewage treatment facilities, renovate and build sewage pipes, and strengthen the sewage collection and treatment capacity. In addition, the sewage needed to be pre-treated to ensure that the sewage reached a certain treatment standard before entering the municipal sewage pipe network. The implementation of the sewage interception project required the investment and support of the government. At the same time, it was necessary to establish a corresponding work system and assessment mechanism to ensure the smooth progress of the project. At present, some cities have begun to implement sewage interception projects and have achieved certain results. However, there were still some problems in the implementation process, such as old and damaged pipe network, sewage overflow, etc., which needed to be further solved. In general, the municipal sewage interception pipe was an important water pollution control project, which had positive significance for improving the quality of the urban water environment.

The sewage interception technology was a water pollution treatment project. By constructing and transforming the sewage pipeline inside the sewage generating unit and connecting it to the sewage pipeline system under the city road, the sewage was transported to the sewage treatment plant for treatment. This technology was the most direct and effective engineering measure in the treatment of black and smelly water bodies, and it was also the premise of other technical measures. The sewage interception pipe could control the discharge of sewage within the city, including sewage outlets, rainwater pipe outlets, etc. It laid sewage interception pipeline along the river and lake, and reasonably set up pumping stations to intercept the sewage and incorporate it into the urban sewage collection and treatment system. The implementation of the sewage interception pipe project needed to consider the elevation of the overflow device's discharge outlet and the water level of the water body, and set up a non-return device to prevent reverse flow during heavy rain. However, the implementation of the sewage interception and management project faced some limiting factors, such as the large amount of work and one-time investment, the difficulty of project implementation, and the long period. In addition, the sewage entering the sewage treatment plant after intercepting the sewage pipe may cause greater operating pressure on the existing urban sewage system and sewage treatment plant, so bypass treatment may be needed.

The sewage treatment standards were divided into Level 1, Level 2, and Level 3. According to the Integrated Waste Water Discharging Standard, the first-class standard was applicable to the discharge of sewage into Class III water areas (except for designated protected areas and swimming areas) and Class II sea areas in Class B. The Level 2 standard is applicable to the discharge of sewage into Class IV and V waters in the standard of the national standard 3838 and Class III sea areas in the standard of the national standard 3097. The Level 3 standard was applicable to the situation where the sewage was discharged into the urban drainage system with a secondary sewage treatment plant. The specific standard values and requirements may vary by region and industry.

The sewage interception network was a water pollution treatment project. By constructing and transforming the sewage pipeline inside the sewage generating unit and connecting it to the sewage pipeline system under the city road, the sewage was transported to the sewage treatment plant for treatment. This method was mainly used to control the sewage discharge outlet along the urban water body, the discharge outlet of the initial rainwater or dry running water of the diversion rainwater pipeline, and the permanent engineering management of the discharge outlet along the combined sewage system. The sewage interception network played an important role in urban sewage treatment.

Fishing could be done in Dagu's sewage river. Moreover, it had been filtered and purified layer by layer. The water quality was very good, and the fish could be eaten. Some fishermen caught a variety of fish such as Crucian carp and carp in the Dagu sewage river. However, it was important to note that the water flow in the Dagu sewage river was relatively large, which might affect the fishing experience. In addition, there were also reports of dead fish floating in some areas of the Dagu River, which might be related to the nearby sewage outlets. Therefore, anglers should choose areas with gentle water currents to fish to ensure that the fish caught were of good quality. In general, fishing was allowed in Dagu's sewage river, but one had to choose a suitable location and pay attention to water quality and environmental issues.

The management of sewage overflow belonged to different departments, depending on the location. If the sewage crossflow occurs in a residential area, the property management company should be contacted for treatment. If the sewage crossflow occurred on the main and secondary roads, the municipal company should be contacted to solve the problem. Therefore, the management department of sewage crossflow depended on the specific situation.
