Life Waste Water Buried Sewage Treatment Equipment

The working principle of
YMDM buried sewage treatment plant to remove organic pollutants and ammonia nitrogen is mainly dependent on the AO biological treatment technology of equipment.Which works in class A, as A result of high concentrations of organic sewage gas state, in the microbial organisms as facultative microorganisms, they will convert the organic nitrogen in wastewater into NH -n, at the same time using organic compounds as electron donor, the NO - N.N O - N into N, but also use part of the organic carbon source and NH -n synthesis of new cellular material. So the grade A pool not only have A certain amount of organic matter removal function, reduce the organic load of subsequent aerobic pool, help digestion, and rely on the existence of relatively high concentration of organic matter in raw water, complete digestion, eventually eliminate the eutrophication pollution of nitrogen, due to the concentration of organic matter in O level have greatly reduce., but there is still A certain amount of organic matter and high NH -n exist. In order to make A further oxidative decomposition of organic matter, at the same time under the condition of carbonation in complete digestion can go smoothly, in O level setting low organic loading of biological contact oxidation pool, pool at level O there are oxygen aerobic microorganisms and the type of bacteria (digestive bacteria), including aerobic microbial decomposition of organic matter into CO2 and H2O, autotrophic bacteria (digestive bacteria) the use of inorganic carbon produced by the decomposition of organic matter or in the air as A source of CO2 and NH -n conversion in the sewage into the NO - N.N O - N.O level A grade part water back into the pool, pool provide electron acceptor for grade A pool, through the digestive function eventually eliminate nitrogen pollution.
The main features

· YMDM buried sewage disposal device can dive below the surface, the surface can be used as green land or square, the device don't cover area, therefore, does not need to build, more do not need heating of the heat preservation.
YMDM - AO, sewage treatment equipment is composed of two set of equipment for steel structure, using the first domestic anticorrosive coatings for corrosion protection.With resistance to acid and alkali salt gasoline kerosene aging resistance to impact mill, with rust protection.Equipment generally after besmear brushs the paint, anti-corrosion life can reach more than 12 years.
· YMDM buried sewage treatment plant of AO biological treatment process using push flow biological contact oxidation pool, its processing effect is better than that of completely mixed or secondary and tertiary series hybrid biological contact oxidation pool completely.Small volume, and it is better than activated sludge pool water applicability, impact resistant performance is good, stable discharging water, no sludge bulking, at the same time in the biological contact oxidation pool using the new elastic solid material, it has a real big surface area, microbial hanging membrane, membrane is convenient, under the condition of same organic load, higher than other fillers on the removal rate of organic matter.To improve the air in water solubility.
, because in the process for biological treatment of AO used the biological contact oxidation pool, its packing is lower, the volume of the load itself in the microbial oxidation stage, therefore less sludge production.In addition, the moisture content of sludge produced by biological contact oxidation pool is far lower than the moisture content of sludge produced by activated sludge pool.Therefore, sewage after TWZ series sewage treatment equipment produced by the sludge quantity is less, only 90 days or so commonly row mud at a time.
· YMDM buried sewage treatment plant in addition to the regular blower sound measures (such as vibration isolation pad, muffler, etc.), also on the inner wall of the blower room set up new sound-absorbing material, make the equipment run time below 50 decibel noise, reduce the impact on the surrounding environment.
· YMDM buried sewage treatment plant with soil deodorization measures, the use of reinforced concrete structure of pool upper airway space set up soil improvement and cloth.When the stench ingredients through the layers of dissolved in the soil contains water and, in turn, because of the surface of the soil adsorption and chemical reaction into soil, was eventually the microbes and achieve the goal of deodorization.
ZWF buried sewage treatment plant of form a complete set of automatic alarm system, electric control system and equipment damage equipment reliability is good, so normally the need of personnel management, monthly or quarterly maintenance and maintenance.

The main design parameters
Pond, at the beginning: YMDM buried sewage treatment plant pond for flat sedimentation basin
Adjust the pool: YMDM buried sewage treatment plant to adjust time of 6 hours.
A. level biological pool: YMDM buried sewage treatment plant biological pool for pushing flow biological contact oxidation pool
O. level biological pool: YMDM - AO level O biological pool to promote type biological contact oxidation pool
The second pond: YMDM buried sewage treatment plant pond for vertical sedimentation basin.
Disinfect pool: YMDM buried sewage treatment plant disinfection pool for vortex reaction pool.
Sludge pools: YMDM buried sewage treatment plant sludge pools and settling basin bucket volume can be stored for 90 days the sum of the sludge, then available dung sucking from sludge into the orifices of sludge after suction bottom of sinotrans.
