After biological treatment, the sewage must enter the secondary Clarifier for sludge water separation, and the clarified treated water can only be discharged.
This type of sludge scraper is suitable for sludge removal in radial flow (circular) sedimentation tanks with a diameter generally not greater than 18m in water supply and drainage projects.
In the process of sewage treatment, an aerator is used to force air into the sewage, so that the sewage in the pond is in contact with the air and oxygenated, and the pond water is stirred.
The vortex air flotation machine is a sewage treatment equipment. What are the factors that affect its operation? The following are the points summarized by the editor, I hope it will be helpful to everyone.
The snail sludge dewatering machine is a common equipment in the environmental protection industry. So what are the operating points during our operation?
The PAC coagulant is rapidly stirred to destabilize the electrolyte in the wastewater, and then the PAM slow stirring bridge is added to make the alum flower formed by flocculation to enter the air floatation machine.
We know that the function of the dissolved gas tank is to ensure that the air can be fully dissolved in the waste water under a certain pressure. What is the air intake method?
During the operation of the shallow air floatation machine, there may be a sudden power outage, so when the shallow air floatation machine has this situation, how to deal with it?
