Domestic sewage equipment，MBR Wastewater Treatment Plant

Domestic sewage treatment equipment

1、 Product overview

1. On the basis of summing up the operating experience of domestic and foreign domestic sewage treatment plants, combined with their own scientific research achievements and engineering practice, an integrated anaerobic wastewater treatment plant is designed. The equipment uses MBR membrane bioreactor to remove BOD5, COD, NH3-N, bacteria and viruses. It has stable and reliable technical performance, good treatment effect, low investment, automatic operation, and convenient maintenance and operation, It does not occupy the surface area, does not need to build houses, and does not need heating and insulation. The integrated domestic sewage treatment equipment can be set to the ground or buried type, and flowers and grass can be planted on the ground of the buried type without affecting the surrounding environment.

2. Treatment and reuse of domestic sewage from hotels, restaurants, sanatoriums, government agencies, schools, troops, hospitals, expressways, railways, factories, mines, tourist attractions and similar small and medium-sized industrial organic wastewater from slaughtering, aquatic product processing, food, etc. The quality of sewage treated by the equipment meets the national discharge standard.

2、 Product features

1. The two-stage biological contact oxidation process adopts plug flow biological contact oxidation, and its treatment effect is better than that of completely mixed or two-stage in series completely mixed biological contact oxidation tank. It is smaller than the activated sludge tank, with strong adaptability to water quality, good impact load resistance, stable effluent quality and no sludge bulking. A new type of elastic solid filler is used in the tank, which has a large specific surface area. Microbes are easy to hang and remove the membrane. Under the same organic load conditions, the organic matter removal rate is high, and the oxygen solubility in the air in water can be improved.

2. Biological contact oxidation method is adopted for biochemical tank. The volume load of filler is relatively low. The microorganism is in its own oxidation stage, and the sludge production is small. It only takes more than three months (90 days) to discharge the sludge (pumped or dehydrated into sludge cake for outward transport).
