Shanghai sewage treatment plant safety evaluation
Abstract：This paper brief introduces the status quo of Bailonggang sewage treatment plant, including sewage treatment plant layout, processing technology and main equipment etc. Main work is to sewage treatment plant safety evaluation. The purpose is to search, analysis and forecast systems have dangerous, harmful factors and may lead to the danger and harm accident consequences and degree, put forward reasonable and feasible safety measures, guide the dangerous source monitoring and accident prevention, in order to achieve the lowest accident rate, minimum loss and optimal safety investment benefit. In this paper, the main dangerous and harmful factors of sewage treatment plant are identified and analyzed. The evaluation mainly according to the sludge treatment system, the sludge treatment system is pided into two units, respectively is sludge treatment system (including the digestive system, drying system, the dehydration system) and biogas processing system, respectively by safety check table method and system for fire and explosion refers to the evaluation of the evaluation. The safety problems of the sewage treatment plant are pointed out and the improvement measures and suggestions are given in the evaluation process. At last, the conclusion of safety evaluation is given.
Key words: safety evaluation; sewage treatment plant; harmful factors; system fire and explosion index evaluation method; safety check list method
