Problems solved by technology

Membrane separation treatment by physical method is relatively feasible, but the main problems in its application are: inconvenient replacement of membrane, high cost of operating power consumption, separation of a large amount of substances that do not need to be separated from water, difficulty in disposal of concentrated solution, etc.
The cost of biological method is low, and it is a relatively promising method. However, how to effectively remove HAAs before the filler is film-coated (from one month to several months), how to maintain the biomass to meet the requirements after film-coating, and the cost of microbial loss Disease risk control and other issues are still to be resolved

Abstract

The invention discloses a device for removing haloacetic acids from drinking water, which mainly comprises a container, a water distributor, a primary absorption structure having a nonpolar adsorption filler layer, a secondary absorption structure having a polar adsorption filler layer, a back wash system, an automatic control system and the like. In raw water treatment, when water passes through the nonpolar filler layer and the polar filler layer in turn, nonpolar organic matters capable of exerting adverse influences on HAAs absorption are removed from water first, so that the HAAs absorption advantages of the subsequent polar filler layer is played fully. Meanwhile, the device solves the problem of carbon loss caused by high back wash degree, the height required of the device for preventing the fillers from losing in back wash is reduced, and the members and operation which are related to the switch between the operation condition and back wash condition are simplified. The device can effectively remove HAAs from water and has small volume, reduces operation energy consumption, is easy for operation and is convenient for management.

Description

[0001] technical field [0002] The invention relates to the technical field of drinking water purification, in particular to a device for removing haloacetic acid in drinking water. [0003] Background technique [0004] With the continuous development of industry and agriculture, a large number of pollutants enter water bodies through different channels, and the problem of drinking water sources being polluted is becoming more and more prominent day and night. For specific water quality problems, there are corresponding patents continuously, such as CN101028945A "Biological Sterilization Device for Defluoridation of Water Source Water", CN101486506 "A Device for Removing Arsenic in Drinking Water", CN101654307 "A Device for Removing Phthalate in Drinking Water" Device", which technically solves the problem of drinking water sanitation and safety, but so far, there is no patent announcement for the removal of haloacetic acid, a disinfection by-product in drinking water. ...
