摘要： 通过实验室小试对几种可能有效消除水中残余消毒剂的方式进行验证，并找出其中最为有效的一种。通过中
试实验对“剩余污泥消除残留有效氯”的方式在实际工程运用中的可行性与经济性进行验证。静态实验表明，采用含有
活性污泥成分，MLSS （混合液悬浮固体的质量浓度） 约4 000 mg/L的泥水混合物对水中残留含氯消毒剂有较好的中和作
用，在充分混合并停留8 h后，水中余氯值可降至0.2 mg/L以下。中试实验结果表明，利用“剩余污泥消除残留有效氯”
的方式在实际污水生化处理系统中完全具有可行性，几乎不额外增加工程造价，同时可消耗部分剩余污泥，降低污泥处
置成本，并且经过中和的污水在进入生化系统后对生化系统已无负面影响。

Abstract: Several possible ways to effectively eliminate the residual disinfectant in the water were verified through a small
laboratory test, and the most effective way was found. The feasibility and economy of this method in actual engineering application
were verified by pilot experiments. Static experiments show that the use of a mud-water mixture containing activated sludge components
and MLSS of about 4 000 mg/L has a good neutralization effect on the residual chlorine-containing disinfectant in the
water. After fully mixing and staying for 8 h, the residual chlorine in the water can be reduced to below 0.2 mg/L. Pilot experiments
show that this method is completely feasible in the actual sewage biochemical treatment system, almost no additional project
cost while consuming part of the remaining sludge, reducing the cost of sludge disposal. And after the neutralized sewage enters
the biochemical system, it has no negative impact on the biochemical system.
