摘　　要：目前,国内农村生活污水有增长快、来源广、污染物质成分复杂、污染物浓度低、处理率不高等特点。伴随着农村生活方式的改善以及农村经济的发展,生活污水量也逐渐上涨,加之村庄分散的特点易导致污水分散,难以集中处理。本文中设计了一个自动化的序批式小型家用污水净化机,自动化控制,维护管理简单,序批式可满足污水时有时无的情况,污水处理部分采用三级过滤、UV/BiPO4/O3处理技术,使净化水达到农业灌溉、地下水回灌、养殖等标准,达到节水减排的目的。At present, in China rural domestic sewage has the characteristics of rapid volume growth, wide sources, complex composition, low concentration of pollutants, and low treatment rate. With the improvement of rural life style and the development of rural economy, the quantity of domestic sewage is also increasing gradually. In addition, the decentralized characteristics of villages tend to lead to decentralized sewage, which is difficult to be treated centrally. So an automated sequencing batch small household sewage purifier was designed, which can realize automatic control, easy to maintain and manage, and the sequencing batch can deal with the situation that sometimes there is no sewage. The sewage treatment part adopts three stage filtration and UV/BiPO 4/O 3 treatment technology. The purified water can reach the standards of agricultural irrigation, groundwater recharge, and aquaculture, and achieve the purpose of saving water and reducing emissions.
