River water filtration and purification process

Abstract

The invention aims to provide a river water filtration and purification process that can remove impurities in river water. And the water purified by the process cannot generate unfavorable effects in later stage use by dyeing and finishing enterprises. A flotation tank is added in front of a coagulation precipitation tank. The river water entering the flotation tank is first mixed with polyaluminum chloride, and then enters the flotation tank. The water obtained by the process can effectively satisfy the requirements of water needed by dyeing and finishing enterprises in production, so that the water expenditure of the enterprises can be substantially reduced. Besides, application of the water to product dyeing has the advantages of good dyeing effect, uniform dyeing and the like.

Description

technical field [0001] The invention relates to a process for filtering and purifying, in particular to a process for filtering and purifying river water. Background technique [0002] In the dyeing and finishing enterprises, the consumption of water is very huge, and the cost of using tap water is very high. In order to reduce costs, enterprises use river water one after another. However, with the deterioration of the environment, the water quality in our rivers is often Class IV water, Category 5 water is even worse. In order to solve the above problems, many dyeing and finishing enterprises have established their own filtration devices, introducing the river water near the enterprise into the enterprise, and then passing through the coagulation sedimentation tank, valveless filter tank, clear water tank, quartz filter, activated carbon filter , sodium ion exchanger, precision filter, soft water pool, etc. to purify the river water, and the treated river water can replace...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the unstable water quality in the river water, it is difficult to remove the impurities in the water, and the current purification device cannot purify all the river water. Therefore, the purified river water is likely to cause damage to the dyeing of the dyeing and finishing enterprises in the later stage of use. Influence, so that the dyed cloth has disadvantages such as poor dyeing effect and poor dyeing uniformity, which has caused adverse effects on the printing and dyeing of the enterprise
