摘要:針對常規(guī)通溝污泥處理工藝高負荷條件下洗砂效率下降、粒徑＜0.2 mm特細砂分離效率較低以及沖洗水消耗量高的問題，武漢市某通溝污泥處理工程采用兩級旋流+砂水分離的改進工藝，將通溝污泥分離成粒徑10 cm以上的大件物質(zhì)、6 mm~10 cm的粗大物質(zhì)、0.075~6 mm的無機砂、2~6 mm的有機渣等，其中0.075~6 mm的無機砂分離效率81.2%，0.075~0.1 mm特細砂分離效率73.4%，回用水利用率達73.1%，為區(qū)域性大型通溝污泥處理站的工程設(shè)計提供參考，有助于排水系統(tǒng)的提質(zhì)增效。
Abstract:Conventional sewer sludge treatment process has the problems of low sand washing efficiency under high load conditions, lower separation efficiency of ultra-fine sand with a particle size of less than 0.2 mm and high washing water consumption. An improved process of two-stage cyclone and sand-water separation was employed in a sewer sludge treatment project in Wuhan, in which the sewer sludge was separated into large substances with particle size over 10 cm, coarse substances with particle size between 6 mm-10 cm, inorganic sand with particle size between 0.075-6 mm and organic residue with particle size between 2-6 mm, among which the separation efficiency of 0.075-6 mm inorganic sand was 81.2%, the separation efficiency of 0.075-0.1 mm ultrafine sand was 73.4%, and the reuse water utilization rate reached 73.1%. The result can provide a reference for engineering design of regional large-scale sewer sludge treatment station, and help to improve the quality and efficiency of the drainage system.
