New anaerobic biofilter manufacturer

New anaerobic biofilter manufacturer

1、 Scope of application: 1. Mainly used for the treatment of domestic sewage with a drainage capacity of 1-24m3/d, usually connected in series after the septic tank; 2. This design adopts a buried type, and its burial depth is determined according to the actual situation.
2、 Working principle:
After passing through the septic tank, the sewage flows automatically into the first stage anaerobic biofilter and passes through a spherical composite packing with a large specific surface area from top to bottom. Due to the lack of air in the filter, the anaerobic microorganisms produced grow in the form of biofilms on the surface of the filter material. When the sewage passes through the surface of the packing material with this biofilm, the organic matter in the sewage is removed by the adsorption of the biofilm, the decomposition and metabolism of microorganisms, and the interception effect of the filter material. Then the sewage enters the secondary anaerobic treatment from bottom to top through the bottom periphery for further biochemical treatment. After that, it flows out through the triangular weir collection tank using the water level difference between the inlet and outlet water. The aged and fallen biofilm settles at the bottom of the filter and is regularly sucked away through the suction pipe. Qianqiu Environment

3. Fill ratio of 60%; Qianqiu Environment
4. Sludge cleaning cycle: one year; Qianqiu Environment
5. Volume load: 0.25kgCOD/m3 · d; Qianqiu Environment
6. Flow rate in the secondary anaerobic zone:<0.5m3/m2 · h.
4、 The technical characteristics of high-efficiency anaerobic biofilters: Qianqiu Environment 1. The effective volume of the sludge bed is large, which can obtain higher loads, increase the concentration of the mixed solution, reduce blockages and short circuits; Qianqiu Environment 2. Compared with USAB, it has less sludge loss, faster reactor start-up speed, simple and convenient operation and management; Qianqiu Environment 3: No need for three-phase separators, simpler structure; Qianqiu Environment 4, low energy consumption, no equipment for sludge reflux and air blowing aeration, biogas production rate of 0.4-0.5m3/kgCOD; Qianqiu Environment 5, especially when treating low concentration dissolved organic wastewater, has a higher COD removal rate and methane production than other similar reactors. Qianqiu Environment Qianqiu Environment V. Construction Precautions: Qianqiu Environment 1. External load conditions should be considered, and the depth of soil cover should be determined according to specific requirements to prevent sewage backflow and pool tilting. Qianqiu Environment 2. After the completion of the pool body production, a water holding test should be conducted. After the water level in the pool is reached to the specified level, the connections at all points should be checked for tightness, and the height of the water outlet weir should be observed for levelness. Adjustments should be made to achieve uniform forced water distribution. Qianqiu Environment 3. During construction or operation, it is strictly prohibited to put or leave other solid pollutants in the pool or pipeline. Qianqiu Environment 4. The foundation of the filter tank is selected based on the on-site bearing capacity. Generally, 100mm original crushed stone can be used, and a 200mm original reinforced concrete foundation can be laid on top. Qianqiu Environment Qianqiu Environment 6. Operation Precautions: Qianqiu Environment 1. During operation, suspended solids and sludge in the septic tank should be cleared on time to prevent solid pollutants from flowing into the tank and causing blockage. Qianqiu Environment 2. During the start-up period of anaerobic biofilters, aerobic biological treatment takes a long time, usually 3-6 months. If conditions permit, mature anaerobic sludge can be introduced to accelerate the formation of biofilms. Qianqiu Environment 3. The filling replacement cycle is 5-8 years, and the sludge cleaning cycle is one year. After expiration, timely maintenance should be carried out. Qianqiu Environment 4. After the construction of the anaerobic filter tank, protective signs should be placed to prohibit heavy vehicles from driving on the top, and fire sources should be prohibited near the ventilation pipe.
Scope of application: Urban apartment buildings, shopping centers, hotels, factory offices, public buildings, hospitals, schools, highways, golf villages, hospitals, military bases, scientific research bases, domestic sewage treatment, etc.
