Abstract

Provided is a water-saving clarification and purification system and a process thereof. Chemicals are added to to-be-treated raw water in a raw water tank and mixed through a multi-section type pipe mixer, the water enters a flocculation reactor with vanes having variable bore diameters for flocculation through rotational flows, then enters a sediment separator for solid-liquid separation, and finally is filtered through a filter, and output water enters a clean water tank to be used. Mud slag separated through the sediment separator is concentrated through a mud accumulation bucket, after concentration, a part of active mud slag flows back to the flocculation reactor through a circulation device, the remaining mud slag is pressed and filtered through a pressing and filtering device, and filtrate flows to the raw water tank, and filter backwashing drain water flows back to the raw water tank. The steps of mixing, flocculation, sediment and filtering are achieved in an integrated high-efficiency clarification and purification device. By means of concentration, circulation and backwashing of the mud slag, water content of the remaining mud slag is reduced. The filtrate of the pressing and filtering device and backwashing water of the filter are recycled to the raw water tank so that exterior drainage rate of the clarification and purification process is greatly decreased and water saving performance of the water-saving clarification and purification system is improved. Compared with a traditional coagulation clarification process, the process has good water saving performance.

Description

technical field [0001] The invention belongs to the technical field of water supply and waste water treatment, and relates to a water-saving clarification and purification system and process suitable for coagulation clarification and softening treatment of surface water, waste water, reclaimed water, sea water, etc. of various water qualities. Background technique [0002] The coagulation and clarification process is to fully mix the water body with the addition of coagulants, and use the ions that are opposite to the colloidal particles in the water produced by the coagulant after ionization in the water to thin the electric double layer on the surface of the colloid through electrical neutralization. Reduce the ζ potential, eliminate the electrostatic repulsion, make the colloidal particles coagulate and destabilize each other to form large particles of alum, which are precipitated and removed from the water, so as to achieve the purpose of water purification. [0003] At ...
