Industrial water feeding treatment system

Abstract

The invention provides an industrial feed water treatment system which comprises a raw water adjusting tank, a mixer, a flocculoreaction tank, a settling pond, a sludge tank, a V-shaped filter and a clean water pond, wherein raw water fed outside a plant is fed into the raw water adjusting tank, lifted to the mixer through the raw water adjusting tank, sufficiently mixed with a coagulant fed by coagulant feeding equipment inside the mixer and subsequently fed into the flocculoreaction tank; a coagulant aid is fed into the flocculoreaction tank; the coagulant and the coagulant aid react with suspended solids in water in the flocculoreaction tank, and then alumen ustum which is compact and easy to deposit can be rapidly formed; effluent of the flocculoreaction tank is fed into the settling pond, then the suspended solids in the water can be deposited; the deposited sludge is fed to the sludge treatment system; effluent of the settling pond is fed into the V-shaped filter to remove the solids in the water; the V-shaped filter is filled with quartz sand and fine gravel; filtered water is fed into the cleaning water pond and is pumped to a production device. By adopting the industrial water feeding treatment system, the flocculation effect as well as the quality of the effluent is improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an industrial water supply treatment system. Background technique [0002] The water consumption in the industrial production process is huge, accounting for more than 20% of the current total water consumption, and with the rapid development of industry, the share of industrial water will continue to increase. Due to the increasing shortage of water resources, water saving Water conservation especially in industrial production processes has become an important task. The traditional industrial water supply preparation process mainly uses coagulation sedimentation + mechanical filtration + positive bed + negative bed + mixed bed process to produce demineralized water. Coagulation, clarification, filtration to remove suspended solids and colloids, ion exchange technology to remove various salt ions in water, but there are two main problems: one is the efficienc...

AI Technical Summary

Problems solved by technology

Coagulation, clarification, filtration to remove suspended solids and colloids, ion exchange technology to remove various salt ions in water, but there are two main problems: one is the efficiency of the pretreatment system is not high, the process is long, the area is large, and the effect unstable

Second, the ion exchange resin needs to be regenerated with high-concentration acid and alkali, and a large amount of acid-base wastewater is discharged. Especially for reclaimed water with a salt content exceeding 1000mg / L, the ion exchange regeneration is very frequent, causing serious environmental pollution and high operating costs.
