Embodiment Construction

[0019] An advanced treatment process for removing disinfection by-products in drinking water, adding a tertiary treatment process to municipal water supply terminals, specifically including:

[0020] (1) First-level flocculation treatment process: the treatment liquid is prepared by mass calculation from 30% sulfate flocculant, 40% organic flocculant, 15% adsorption resin and the rest of the chelating cleaning agent; The time is 30 minutes;

[0021] (2) Two-stage nanofiltration membrane treatment process: the nanofiltration membrane is prepared from aromatic polyamide, the operating pressure is 1.0MPa; the operating temperature is 40°C;

[0022] (3) Three-stage composite filter material treatment process: the composite filter material is calculated by mass by 22 parts of peanut shell activated carbon, 16 parts of modified activated carbon, 12 parts of far-infrared sintered balls, 8 parts of quartz sand, and 20 parts of ceramsite filter material , 7 parts of asbestos, 8 parts ...

Abstract

The invention discloses a deep treatment process for removing toxic and side products from drinking water. Three grades of treatment processes, particularly comprising a first-grade flocculating treatment process, a second-grade nano-filtration membrane treatment process and a third-grade compound filter material treatment process, are added to a municipal water supply terminal for performing combined treatment; the deep treatment process for removing the toxic and side products from the drinking water has a high-efficiency effect of purifying water quality, and particularly, has a good removal effect on a disinfection by-product, namely, halogenated hydrocarbon, in the drinking water; moreover, the process cost is not high; the used chemicals are common; the operating requirement is low.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an advanced treatment process for removing disinfection by-products in drinking water. Background technique [0002] Water quality is a major focus of people's life in society. At present, drinking water purification technology and engineering facilities are important measures to ensure people's drinking water hygiene and safety. However, in the process of disinfection treatment of drinking water, the generation of disinfection by-products is unavoidable. However, the usual municipal treatment often has a little flaw in this aspect, which fails to achieve very good results. [0003] Therefore, how to seek an advanced treatment process for drinking water that has an efficient water purification effect and effectively removes disinfection by-products during the water purification process is a topic worthy of research. Contents of the invention [0004] Purpose of the invention: In...
