【摘要】 针对我国北方矿区低温低浓度生活污水的特点,采用混凝沉淀与生物滤池相结合的工艺进行试验研究,结果表明:该工艺通过负压实现无泵自冲洗,具有处理效果好、占地小、滤层阻力小、能耗低等优点,系统出水可以达到生活杂用水水质标准,完全可进行资源化回用。更多还原

【Abstract】 The technique of coagulative precipitation combining with biological aerated filter is fit for treatment of domestic sewage in mining area under lower temperature and aeration conditions. It possesses merits of good effect, small floor area, low resistance, low energy consumption and automatic backwash without pumps. The quality of influent water measures up to the standard of water reuse and reclamation.更多还原
