Abstract: This paper introduces the technological process of Chengguan town of Datong County of Xining City, the firstsewage treatment plant, the structure and main parameters of the equipment. Station adopts JSBC technology of sewage treatment, the technology of Bacillus bacteria is mainly composed of a rotary net biological contact device, biological aeration tank, two sedimentation tank, the fostering ofcomposition, has the advantages of small occupation area, low energy consumption characteristics, and the effluent quality to achieve "urban sewage treatment plant pollutant discharge standard" (GB18918-2002) in an A standard.

隨著我國對處理后排放的污水中氮、磷濃度的要求越來越嚴(yán)格,標(biāo)準(zhǔn)也越來越高,催生了一些污水生物處理工藝的蓬勃發(fā)展。JSBC(Joint System Biological Contact)工藝是近幾年在我國出現(xiàn)的一種污水處理生化工藝,且該工藝處理技術(shù)日益成熟。本文以西寧市大通縣城關(guān)鎮(zhèn)第一污水處理站工程為例,介紹JSBC工藝的設(shè)計及運行經(jīng)驗。
