摘要
针对使用次氯酸钠试剂进行消毒以及另建消毒池费用太高的情况,高雄污水排海工程利用电解海水得到次氯酸钠用于排海污水的消毒处理,同时将放流管作为消毒剂与污水接触的反应器,降低了运行成本。本文对该消毒方案进行了试验室模拟,研究了反应过程中余氯的变化规律、有效氯投加量、停留时间以及流速对消毒效果的影响。结果表明流速对灭菌效率影响不大,控制加氯量为2.0mg/L,保证30～60min的接触时间,即可保证污水进入海水前达到满意的灭菌率。
In the situation of our country at present,in the sewage marine disposal, the self-purification capacity of marine waters is the superior choice to solve the environmental problem of coastal cities. The usage of sodium hypochlorite electrolysed from sea water as disinfection is better than the high expenditure of using sodium hypochlorite reagent and building disinfection pool. At the same time, the discharge pipe was used as reactor for infection and sewage mixing. These acts reduced the run cost. The simulating disinfection test was made in lab. The variety rule of remaining chlorine during the reaction, the efficient chlorine putting in and the disinfection effect by velocity of flow is studied. The results showed that the velocity of flow has little influence on the disinfection. The satisfactory disinfection effect can be reached when the efficient chlorine is 2.0 mg/L and the contact time is between 30～60 min.
