MBR wastewater treatment process is an effective combination of membrane separation technology and biological treatment technology. This technical process design can not only effectively achieve the purpose of mud-water separation, but also has the incomparable advantages of the three-stage sewage treatment process: high treatment efficiency, good effluent quality; compact equipment, small footprint; easy to realize information automation Simple method to control and run cost management! Let’s learn about the treatment methods of landscape water.
The main purpose of landscape sewage treatment is to avoid the occurrence of eutrophication of water bodies, control the concentration of organic matter, SS, N, P and other water quality factors in the water, so as to Fundamentally solve the water quality problem of landscape water.
Based on the water quality characteristics of landscape water, the air flotation + biochemical water treatment process can be used to effectively treat landscape water. When the fine suspended solids in the water body flocculate into large particles, they float to the surface of the water under the support of micron-sized bubbles released by air flotation. It is scraped to the slag pool by a slag scraper and removed. The water after air flotation treatment is then biochemically treated to remove organic matter in the water body before it reaches the standard. The outlet pump lifts the water to each outlet and discharges it, which circulates the water in the entire landscape lake and avoids the formation of stagnant water areas.
This process solves the problem of eutrophication of water bodies by effectively reducing the contents of SS, N, P and organic matter in the water body.
process design features
① Set up a fine grid tank in front of the membrane treatment system, and set up an oil skimming device on the aeration grit tank , which can ensure a good operating environment and treatment effect of the
treatment system in the later stage.
② This process adds a second anoxic zone to the original A2/O. The second anoxic zone mainly uses microbial endogenous metabolism as a carbon source for denitrification, thereby ensuring that the TN value of the effluent reaches the standard.
③ The combined construction of biochemical pool , membrane pool, and disinfection pool improves water conservancy conditions, reduces water head loss, effectively saves land area, and reduces project costs.
uses the "air flotation + biochemical" water treatment process to circulate the lake water, ensuring the safety of the lake water quality and the landscape viewing effect, and meeting people's growing hydrophilic requirements!
