摘要
采用八种国内污水处理厂常见的工艺进行技术经济综合评价,包括普通曝气工艺、水解-好氧工艺、AB工艺、A/O工艺、A2/O工艺、交替式氧化沟工艺、一体化氧化沟工艺和SBR工艺.通过抽样调查分析比较了这些处理工艺的处理效果、经济水平和工程实施三大类13个评价因子,建立了多评价因子的参数评价体系并设定其中各项因子的权值.评价采用模糊数学的改进方法,并将评价结果与专家评价进行比较.结果表明:A2/O,A/O和交替式氧化沟三大工艺较为适用于大中型城市建设中的污水处理厂,其中A2/O的表现尤为突出.
Comprehensive technical and economic evaluations were performed for eight kinds of domestic sewage treatment processes commonly used in wastewater treatment plants in China, including conventional aeration, hydrolysis-aerobic process, adsorption biodegradation （AB） method, anacrobic oxic （A/O） method, （A2/O） anaerobic-anoxic-Oxic method, alternating type oxidation ditch, integrated oxidation ditch and sequencing batch reactor （SBR）. Three major categories of total 13 evaluation factors, including treatment effect, economic aspect and project implementation were analyzed and compared through a sampling investigation. A multi-factor evaluation system was established and the factor weights were set. Evaluations were performed with fuzzy mathematics method and the results were compared with those of expert evaluations. Research results show that A2/O, A/O and oxidation ditch are more applicable to the sewage treatment plants in large or medium-sized cities, among which A2/O is particularly prominent.
