2. The key to implement single household management, joint household management, whole village expropriation and joint village transformation is to set the actual height appropriately;
3. It aims to reduce environmental pollution control, construction investment and operation cost, pipe network concentration, garbage collection and treatment.
China's sewage treatment started late and developed rapidly. Used for contact oxidation, AB, A/O, oxidation ditch, SBR, aerated filter and diversion aerated filter of rural sewage treatment equipment or facilities.
The new sewage treatment process with independent intellectual property rights is the same as the continuous treatment process: hydrolysis-diversion aerated filter, anaerobic-diversion aerated filter, air flotation-diversion aerated filter, rapid sedimentation-diversion aerated filter, ultrasonic-diversion aerated filter, microwave-diversion aerated filter, ozone-diversion aerated filter and so on.
The original sewage treatment project of diversion aerated filter was upgraded to remove nitrogen and phosphorus, and AB diversion aerated filter was developed in combination with water surface and its process. A/O shunt aeration filter; A2/O- split aeration filter; Oxidation ditch-diversion aeration filter; SBR- diversion aeration filter; Biological contact oxidation-split aeration filter and other advanced treatment processes.
The diversion aerated filter was designed by eight designers, including aerated filter, contact oxidation, biofilm, intermittent aeration, rapid filtration, sedimentation, nitrification and denitrification, and rapid filtration of influent. Combined with the secondary or tertiary sewage treatment process, a new sewage treatment process and technology was developed and patented in 2005.
