Abstract  

To solve the water-quality safety and harmlessness problem of effluent from wastewater treatment, COD was adopted as a regular indicator, IC50 of wheat root elongation and IC50 of germination rate of wheat seeds were regarded as ecotoxicological indicators, and the three controlling parameters (sludge backflow rate qv, hydraulic retention time t and mixed liquid suspended solid concentration ρB1) of the modified Biolak process for treatment of mixed chemical industrial wastewater from a wastewater lagoon in Tianjin were explored; and technique optimization and process improvement of the microelectrolysis-Biolak were done from the viewpoint of toxicity control. The results showed that substances with certain ecotoxicity and organic substances with enhanced toxicity after treatment occurred in the effluent, thus resulting in the difference in optimum technical conditions of wheat root elongation indicators, seed germination rate indicators and other conventional indicators.

基于生态安全的混合化工废水处理工艺

为了解决污水处理出水水质安全与无害化这一问题,采用化学需氧量(COD)作为常规指标,小麦根伸长IC50和发芽率IC50作为生态毒性指标.对改进百乐克工艺处理天津某污水库存量混合化工废水的污泥回流速率qV、水力停留时间t和混合液污泥浓度ρB1 3个控制参数进行试验,并从毒性控制的角度对微电解-百乐克工艺进行优化和改进研究.结果表明,由于污水中存在具有一定生态毒性的物质和经工艺处理后毒性增强的有机物,导致小麦根伸长、小麦发芽率毒性指标与常规指标的最优工艺条件各不相同.
