suspended matters and other organic substances are attached to the surface layer of the precipitated slurry, the added medicines need to decompose organic substances in water, the decomposed slurry is discharged from a sludge discharge valve at the bottom, and the rising flow rate and the dosing amount of water have great influence on the decomposition rate of the slurry due to the fact that chemical oxygen demand is involved in the reaction of the organic substances and strong oxidants are contained in the added medicines;
referring to fig. 5(a), a graph of the effect of the amount of added chemicals on the raw water removal rate shows the reaction rate of organic matter attached to the slurry;
the chemical oxygen demand removal rate is highest when the medicine adding amount is about 350-600 mg/L, and the required chemical oxygen demand removal rate is highest when the medicine adding amount is 400-600 mg/L, tests show that the utilization rates of the chemical oxygen demand removal rate and the required chemical oxygen demand removal rate are both required to be highest when the chemical oxygen demand removal rate is applied, when the medicine adding amount is too much, alum flowers formed by violent reaction of mud attached organic matters are too loose and not easy to settle, and when the medicine adding amount is too much, the medicine is remained in purified effluent water due to excessive medicine adding, so that the effluent water turns yellow and wastes; the dosage of the medicament is related to the content of suspended matters in raw water, but the device has certain impact resistance to organic load, so the optimal dosage can be preliminarily determined, and the turbidity removal rate is highest when the dosage is less than about 500mg/L by comprehensive consideration, and the sludge can be well settled due to enough density of precipitate.

The chemical oxygen demand removal rate is small in water inflow, the rising flow rate of clean water is small, the hydraulic retention time of inflow water in the claw water purifier 5 is long, sufficient clarification time is provided and basically kept above 80%, the middle curve is reduced due to disturbance of the mud valve on water flow, and removal rate fluctuation occurs.
