Project overview:

This project is a sewage treatment equipment project exported to Bangkok, Thailand. The treated water volume is 40m3/d, the treatment process is AO+MBBR process, and the effluent standard is Class A standard.

Process introduction:

This project is an integrated sewage treatment equipment for foreign trade export, and the process designed by Zhongqiao Qidi is AO+MBBR process.

Among them, A in AO process refers to anaerobic section (abbreviated as Anacrobic), which is used for nitrogen and phosphorus removal; O refers to aerobic section (abbreviated as Oxic). Before the anoxic pond, the organic carbon in sewage is used by denitrifying bacteria, which can reduce the organic load of climate aerobic pond. The alkalinity produced by denitrification can compensate the alkalinity demand of nitrification in aerobic pond. After the aerobic and anoxic tank, the organic pollutants remaining in denitrification can be further removed, and the effluent quality can be improved.

MBBR is the abbreviation of Moving Bed Biofilm Reactor, which is called moving bed biofilm process. Suspended fillers with specific gravity close to that of water, large effective specific surface area and suitable for microbial adhesion and growth are needed. At present, Zhongqiao Qidi has successfully developed and matured in the market, and also has corresponding industry standards, and has successful project cases all over the country. MBBR integrated sewage treatment equipment uses the basic principle of biofilm process, and combines the advantages of activated sludge process. It takes suspended filler as the carrier of microbial growth, and realizes high-efficiency sewage treatment through full fluidization of suspended filler in secondary biochemical pool.

Advantages of sewage treatment equipment exported to Bangkok, Thailand;

1. Good denitrification capacity: Aerobic, anoxic and anaerobic environments are formed on the packing. Nitrification and denitrification can take place in one reactor, which has a good effect on ammonia nitrogen removal.

2. Good organic matter removal effect: the sludge concentration in the reactor is high, and the general sludge concentration is 5-10 times that of the common activated sludge method, which can be as high as 30-40g/L. The treatment efficiency of organic matters is improved, and the impact load resistance is strong.

3. Easy maintenance and management: there is no need to set a filler bracket in the aeration tank, which is convenient for the maintenance of the filler and aeration device at the bottom of the tank.

4. Zhongqiao Qidi made a deep study on the chemical characteristics of the filler surface and the shedding mechanism of the suspended filler, and increased the specific surface area of the filler; Combined filler manufacturers used activated carbon, starch, gelatin, etc. as bioactive additives, so that suspended fillers could promote the growth and reproduction of microorganisms.

5. Through the study of reactor hydrodynamics, Zhongqiao Enlighten determines the shape of the reactor, which can achieve the optimal reactor structure, thus avoiding packing accumulation and reducing energy consumption.
