The sequence of sewage treatment was: intercepting well, coarse grid, sewage pump, fine grid, settling basin, biochemical pool.
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 formula for the order of the four mixed operations could be summarized as follows: In a formula without parenthesis, if there was only addition, substitution, multiplication, or division, the calculation had to be done from left to right. If there were addition, multiplication, and division in the formula, the multiplication and division had to be calculated first, followed by addition and division. If the formula had parenthesis, he had to calculate the one inside the parenthesis first, then the one outside the parenthesis. The calculation order in the parenthesis follows the above rules.

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.
