Embodiment Construction
[0034] see figure 1 and figure 2 , the water purification treatment process of multi-stage strengthened water body self-purification and hydraulic control of the present invention is characterized in that comprising the following steps:
[0035] 1) Analyze the change of raw water quality and find out the change rule of raw water quality. In order to improve the economy of purification treatment, avoid the time period of extremely unfavorable water diversion, such as high tide or other periods that will greatly affect the quality of incoming water; try to arrange purification Time period of treatment: the turbidity of diversion water shall not exceed 500NTU, and the salinity shall not exceed 250ppm. If the water is diverted when the turbidity exceeds 500NTU, the treatment cost will be higher. If the salinity exceeds 250ppm, considering the downstream river ecosystem, water diversion is not recommended.
[0036]2) Dosing a coagulant in proportion before the water diversion p...
