How to treat the wastewater from cofferdams
Thread Content
Help, hello everyone. There are dikes surrounding the site where gas, water, and other substances are separated; they were originally meant for use with rainwater, but in the end that water ends up in the rainwater system. There is a lot of gas and water in the cofferdam now, contaminating the rainwater system. How can rainwater and gas moisture be treated separately? Where should the gas and water that need to be discharged on-site be sent?
Polluted rainwater cannot be discharged directly; it must be sent to the sewage system for treatment.
In general, a separate system for rainwater and sewage is designed in water supply and drainage projects. It is recommended to add it.
During water supply and drainage design, separate systems for rainwater and wastewater are implemented
Is it the site for gas-water separation? Is it a coal storage area?
The water inside the cofferdam should be directed into the sewage system; at least the initial rainwater during the first 15 minutes should be sent to the rainwater system. The direction of the water flow is controlled by the gates.
Install a switching valve to achieve separation of cleaning water and waste water
Generally, two outlets are provided: one leading to the rainwater system and the other to the sewage system.
A rainfall, the first rain. Can gas and water be directly discharged through the sewage outlet in your area? The kind of gas water that contains a lot of tar.
Hello, it’s not a coal yard. It is the water produced by gasification
Hello, which sewage system are you referring to? Can gas water containing tar be discharged? The water from the cofferdam here can go to two places: one is the rainwater system, and the other is the pre-rainwater system. No discharge of dirty gas and water is allowed.
