aiming at the specific pollution of iron and manganese generated in the water period of a water source, six emergency disposal methods for single water pollution are adopted by the same lines at home and abroad:
the method is effective for low-concentration iron and manganese pollution indexes, has no obvious effect on high-concentration iron and manganese pollution indexes, and can naturally lose efficacy after long-time use;
secondly, iron and manganese indexes are removed by adopting sodium hypochlorite preoxidation of a disinfectant owned by a water plant, the method is effective in removing low-concentration iron and manganese pollution indexes, and is basically ineffective when the iron and manganese indexes are higher; when sodium hypochlorite is used as a disinfectant in a water plant, the sodium hypochlorite is used as an oxidant for removing iron and manganese, so that the total dosage of the sodium hypochlorite is increased rapidly, and the index of chlorate which is a disinfection byproduct of factory water exceeds the standard;
thirdly, the iron and manganese indexes are removed by increasing the adding amount of the flocculating agent, the method has low removal rate of the pollution indexes of iron and manganese in the water source water, and the pollution indexes with high concentration cannot be effectively solved;
fourthly, a chlorine dioxide pre-oxidation method is adopted to remove the iron and manganese indexes, when chlorine dioxide is used as an 'iron and manganese' remover, chlorate and chlorite byproducts are synchronously generated, the effect is good when the pollution indexes of low-concentration 'iron and manganese' are treated, and the indexes of the chlorate and the chlorite, which are sterilization byproducts of the factory water, exceed the standard when the pollution indexes of high-concentration 'iron and manganese' are treated;
fifthly, the indexes of iron and manganese are removed by adopting a water flow through stage natural falling and blast aeration oxidation method, the method has certain effect on the pollution indexes of low-concentration iron and manganese, and basically has no removal effect on the pollution indexes of high-concentration iron and manganese;
sixthly, the iron and manganese indexes are removed by adopting an ozone oxidation method, and in the method, ozone purchase price is high, equipment investment is large, operation in the using process is complex, and a large operation safety risk is caused;
when the specific pollution accidents of iron and manganese generated in the water source water period are treated in China, the continuous and effective operation of a disinfection process is hardly ensured by adopting the traditional single-flow oxidation disinfection technology, the iron and manganese pollution is removed and treated by adopting the single-flow technology, an intelligent management system is not configured, the aims of accuracy, effectiveness, safety and convenience are not achieved in the specific implementation process, and the problems of the exceeding standard of iron and manganese, the disinfection by-product problem and the disinfection allowance index of factory water in the water supply industry cannot be synchronously solved.
