一、前言茂名石油工业公司污水处理场的生化处理装置,原设计能力为800t/h,已于1976年投产.对环境保护起到了一定的积极作用.几年来,公司进行污水归类,清污分流等作了不少有成效的工作.但是随着加工深度的增加,排污量增大,水质愈来愈复杂,使曝气池的负荷不断增大,加上由于曝气池本身存在对水质波动接受能力较差的弱点,生化 I. Introduction Maoming Petroleum Industry Company sewage treatment plant biochemical treatment plant, the original design capacity of 800t / h, put into operation in 1976. Environmental protection has played a certain positive role. In recent years, the company sewage classification, cleaning Diversion, made a lot of effective work.However, as the processing depth increases, the amount of sewage increases, the water quality is more and more complex, so that the load on the aeration tank increases, coupled with the aeration tank itself, there is water quality Volatility vulnerable to weaknesses, biochemistry
