Biochemical tank is a kind of sewage treatment equipment, the main function is to purify most of the pollutant substances in the sewage, and decompose the organic matter in the sewage into inorganic matter through the microorganisms in the biochemical tank. But in this process of decomposition, it is easy to produce foam, and a large amount of foam floats on the surface of the biochemical pool. The generation of foam will be harmful to the water treatment process and the environment, so it is very important to effectively control and eliminate the foam in the biochemical tank. There are many ways to eliminate controlled biochemical pool foam, among which, useDefoamer for biological water treatmentIt is a method used by most people, because the use of defoamer is not only simple and convenient, but also effective in controlling the generation of foam and speeding up the efficiency of sewage treatment.
Application scenario diagram of biological water treatment defoamer).
If the foam of the biochemical tank is not controlled in time, it will cause some impacts, the biological foam on the surface of the biochemical tank may overflow, causing external environmental pollution, the biological foam is generally viscous, it will roll a large amount of activated sludge and other solid substances into the floating foam layer of the aeration tank, and the foam layer churns on the surface of the aeration tank, hindering oxygen from entering the aeration tank mixture, reducing the oxygenation efficiency, especially the mechanical surface exposure mode.
On December 30, Ms. Chen received a call from a person in charge of Weihai City, Shandong Province, who said that there was a large amount of foam in the biochemical tank, and he wanted to consult whether there was a suitable defoaming and antifoaming plan, and the requirements were not to affect the water quality indicators. Fungi involved in the formation of biological foam have their own suitable growth temperatures, and foaming can occur when the environment or water temperature is favorable for their growth.
Defoamer for biological water treatmentIt is manufactured by polyether esterified products in the first order, which is a silicon-free product, with strong defoaming and foam inhibition power, low dosage, does not affect the basic properties of the foaming system, has a wide pH value and temperature application range, is easy to disperse in water, does not harm the microorganisms in the water, and will not produce secondary bubbles.
