Description
Technical field
The present invention relates to sewage treatment area, be specially a kind of SBR sewage disposal system and using method thereof.
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 lack of water 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.
SBR sewage treatment process i.e. sequencing batch reactor, it is based on the microorganism the produced technique to the activated sludge process of the biological wastewater treatment that the pollutants such as the organic matter in sewage, ammonia nitrogen are explained under aerobic condition that suspends.Run with intermittent mode chronologically, change Activated Sludge Growth environment, the sewage disposal technology extensively admitted by the whole world and use.
SBR technique is by reaction, precipitation and in a pond body, be respectively completed in the body of same pond into water, react, precipitate, draining, five processes such as idle.SBR technique is high to the removal efficiency of pollutant, floor space is few, layout is tight, the method for operation is flexible, and the change to the water yield and water quality has bigger adaptability, just has bigger flexibility, and operating cost is low in terms of operation operational management.
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.
