Method for performing purification treatment to surface raw water and water purifying device

Abstract

The invention relates to a method for performing purification treatment to surface raw water and a water purifying device. The method comprises the step of performing rough filtration, medicine-adding blended disinfection, flocculation precipitation, and valvedless filtration to the surface raw water with a turbidity lower than 1500mg / l, to get purified water reaching domestic water standards. The water purifying device mainly comprises a rough filter, a medicine-adding blender, a flocculation precipitator, and a valvedless filter group, wherein the medicine-adding blender is connected to the rear part of the rough filter and connected with a medicine adding device for allocating disinfection water agent through a dosing pump or a valve; the rear part of the medicine-adding blender is connected with the flocculation precipitator and the valvedless filter; the flocculation precipitator comprises a lower part for flocculation reaction and an upper part for inclined pipe precipitation; and the flocculation reaction adopts powdery aluminium chlorohydroxide or aluminium sulphate as flocculation reactant. The invention has the advantages of compact and reasonable structure, operation convenience, running stability, good treatment effect, low construction cost, lower running cost, etc., and can basically meet special use requirements of countryside and small and medium enterprises.

Description

Technical field [0001] The invention relates to a method and a water purification device for purifying surface raw water, belonging to the technical field of water treatment. Background technique [0002] The quality of people’s living water is directly related to people’s health. With the increasing development of industrialized production, the pollution of the living environment in cities and surrounding areas has become more and more serious, and the quality of people’s drinking water has attracted more and more attention from the society. . Although the current water treatment and purification technology is quite mature, and it can even purify the sludge water into water that can be directly drinkable, different purification treatment technologies have different effects on water purification, and there are different costs. To make the purification effect good, it often requires a large investment. Therefore, for the majority of rural areas and small and medium-sized ...
