Abstract

The invention discloses an integrated sewage treatment system and an application method thereof. The integrated sewage treatment system comprises a water inlet, a pre-denitration pond, an anaerobic pond, an anoxic pond, an aerobic pond, a settling pond and a water outlet. According to the application method, firstly, a container is opened to make immobilized microorganism balls flow into the system, then the immobilized microorganism balls long in use time are collected, and lastly the collected immobilized microorganism balls are remade. The immobilized microorganism balls used in the integrated sewage treatment system and the application method of the integrated sewage treatment system not only can keep the activity of microorganisms and purify water but also can separate mud and water and is good in settling performance; the diameter of the immobilized microorganism balls is selected properly, and the immobilized microorganism balls can be suspended without a large magnetic field; under the action of the magnetic field, the immobilized microorganism balls can be in a suspended state, and the activity of the microorganisms can also be improved; the immobilized microorganism balls can be recycled, and therefore the microorganisms in the immobilized microorganism balls are always in a high-activity state.

Description

A kind of integrated effluent disposal system and using method thereof
Technical field
The present invention relates to sewage treatment area, be specially a kind of integrated effluent disposal system.
Background technology
China is the most unbalanced country of distribution of water resources, and the water resource that each place has is the most unbalanced, generally one hydropenia country, and the whole nation has the city of 70% to be in exsiccosis;China or a with serious pollution country of water simultaneously, annual because water pollutes the loss caused accounts for the 2% of GDP, water pollution condition is constantly aggravated so that sewage disposal and regeneration industry are by unprecedented concern.
In pre-denitration pond, a part of immobilized microorganism ball is come by sedimentation tank backflow, and pre-denitration pond is for removing the nitrate carried in immobilized microorganism ball, so that the efficiency that immobilized microorganism ball discharges phosphorus in anaerobic pond is greatly improved;Being mainly used in anaerobic pond discharging phosphorus, partial organic substances carries out ammonification simultaneously, also can remove the COD in water;Being mainly used in denitrogenation in anoxic pond, nitrate nitrogen is back to anoxic pond by interior circulation by Aerobic Pond;Aerobic Pond is used for removing BOD in water, ammonia and nitrogen organic and nitrification and absorption phosphorus, and Organic substance in water is decomposed into inorganic matter;Sedimentation tank is used for purifying water, and the water after sedimentation tank precipitates can be expelled directly out.
The effect of detention tank is mainly mud-water separation, and the method that routine uses is free sedimentation, flocculation sediment, group's precipitation and compression precipitating, but method of each precipitation has respective shortcoming, or the sedimentation time is oversize, or mud-water separation is not thorough, settleability is bad.
