Water supplying treatment device and treatment method

Abstract

The invention discloses a water supplying treatment device. A pretreatment module is connected with a sand filter tank, the sand filter tank is connected with an advanced treatment module, and the advanced treatment module is connected with a clear-water pool; the pretreatment module, the sand filter tank and the advanced treatment module are connected with a sludge treatment module, and the sludge treatment module is connected to an inlet of the pretreatment module through a pipeline or a channel; and the pretreatment module, the sand filter tank, the advanced treatment module and the sludgetreatment module are arranged adjacent to each other, the pretreatment module, the sand filter tank and the advanced treatment module are located above the sludge treatment module, and the pretreatment module, the sand filter tank and the advanced treatment module are connected to the sludge treatment module through a channel. The invention also discloses a water supplying treatment method. The treatment device provided by the invention can ensure that the quality of discharged water achieves a qualitative leap, production wastewater is effectively treated, environmental burden is reduced, thefloor space is saved, and the economic benefits are obvious.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a feedwater treatment device and a treatment method. Background technique [0002] Raw water with low turbidity and high algae all year round, and occasionally high turbidity is a difficult problem in the field of water treatment at home and abroad. In the existing technology, the treatment process of the water supply plant is generally "flocculation + sedimentation + filtration". It has been used for decades, and the effect of treating raw water with stable water quality is still good, but it cannot treat the raw water of the above special water quality. There are many problems in the treatment process. insurmountable problem. [0003] In seasons with less rain, the turbidity of raw water is often low, and the effect of conventional flocculation and sedimentation is poor. The precipitated water contains a large number of fine suspended particles. After this water enters...

AI Technical Summary

Problems solved by technology

Because the discharge of wastewater produced by the water supply plant is discontinuous and intermittent, and the sludge concentration of the water supply plant is lower than that of the sewage plant, and the sludge composition of the water supply plant is different from that of the sewage plant, the continuous operation of the radial flow sedimentation tank requires continuous operation. , The required sludge concentration and composition are also different, so not only the operation is prone to problems, but also occupies a huge area, resulting in a great waste of investment
