摘　　要：以某高校的实验室洗液废水和几种代表性废液混合液为试验对象,用还原中和共沉淀法对废水中的铬进行毒性降解试验。结果表明:废液的pH、还原剂种类、还原剂的投加量等对铬的去除率有一定的影响。经处理后的出水虽不能严格达到国家污水排放标准,但由于其设备、操作简单,实际应用性强。This article used the laboratory lotion waste water and several kinds of typical waste liquid to mixture as the test target, and to have a toxicity degrade test of chromium. The result shows that the pH of the waste water, the kind of reducing agent, and the input amount of the reducing agent have certain influence on the removing rate of chromium in the reductive deposition treatment. Although after the treatment it can not reach the discharge standard of national sewage strictly, it has a bright future of practical application for its simple equipment and operating.
