The issue of water environment is influenced by many aspects. Some industries such as dyeing and printing, mechanical processing, auto repair, electroplating and chemical engineering are relatively more affected. The relevant environmental protection departments have required enterprises to conduct online water quality monitoring before discharging treated sewage and wastewater to ensure that the water quality meets the discharge standards. In this article, we will learn what to do with rainwater and sewage after rain and how to deal with them better.
To improve the sewage and rainwater collection systems, enterprises should make efforts to separate sewage from rainwater. Some production and domestic sewage (mainly including backwash water, cleaning water, cooling water, etc.) should be discharged into the sewage outlet. If it is some rainwater from the factory area, it should be discharged through the rainwater outlet separately. Each production area can only have one pollution discharge outlet and one rainwater discharge outlet. If there are special circumstances, an application is required before additional outlets can be added.
In addition, it is necessary to do a good job in the standardized construction of sewage and rainwater discharge outlets. The specific desktop is as follows for reference
1.How can we do a good job in the operation of sewage discharge outlets? There are requirements for the length, width and other aspects of the sewage discharge outlet. In addition, decorative tiles should be pasted on the inner three sides, sampling ports should be set up, and it should be connected to the environmental protection department to facilitate real-time monitoring of water quality changes. Of course, another very important point is that relevant safety measures cannot be lacking!
2.The rainwater discharge outlet is actually similar to the sewage discharge outlet, which involves these tasks. It should be noted that for some enterprises that use oil, oil removal treatment facilities should be set up before the discharge outlet, and these oily wastes should be treated in a timely manner and classified as hazardous waste for management.
The phenomenon of rainwater runoff pollution is referred to as non-point source pollution in water quality pollution, which is sudden and discontinuous pollution. The initial rainwater itself has a high content of pollutants. Moreover, it will continuously spread along with the runoff. During this process, the rainwater will also be washed away, which will continuously reduce the content of pollutants in the rainwater. As for how to calculate the initial rainwater in the factory area, this depends on the drainage project. The specific situation is not the focus here, so I won’t elaborate further!
