Background

The mechanical stirring clarification tank is a device which uses machinery to lift and stir water, promotes sludge circulation, and makes solid impurities in the water contact with formed sludge for flocculation and separation of sediment. The hydration chemical mechanical stirring accelerated clarification tank consists of a first flocculation chamber, a second flocculation chamber and a separation chamber. In the first and second flocculation chambers, the colloid in the raw water and the return sludge are flocculated by contact, and separated in the separation chamber after being coagulated into large flocs, and the clear water is discharged upwards through the water collecting tank. One part of the sinking sludge enters the lower side end of the separation chamber and is discharged through a sludge discharge pipe, and the other part enters the first flocculation chamber along the backflow seam for flocculation discharge. Generally, when the wastewater is treated, the suspended matters entering a mechanical stirring clarification tank are generally applied to less than 1000mg/L, and the suspended matters are allowed to reach 3000-5000 mg/L in a short time. But when the large-traffic time of intaking of feed liquor pipe, cause first, two flocculation rooms in the pond to suffer the impact, required medicament volume can not in time be adjusted simultaneously, causes machinery to accelerate clarification tank operation effect and reduces, produces "turning over the pond" phenomenon, and calcium magnesium ion can not effectively be got rid of, directly influences the normal operating of back system.
