Problems solved by technology

The first type, alternative disinfectants include ozone, potassium permanganate, etc., but ozone decomposes quickly in water, and the continuous disinfection effect is not as good as that of chlorine, and the cost is high. In addition, these alternative disinfectants will also cause secondary pollution, and the produced substances It is also carcinogenic; second, improved water treatment methods include activated carbon adsorption method, membrane filtration method, biological oxidation method, etc., but there will be problems such as poor treatment effect, short service life of equipment, and treatment cost.

Embodiment １

[0030] A treatment process for disinfection by-products of drinking water of the present invention, the water source is extracted to the water plant, then through coagulation, sedimentation, filtration, sent to the clean water tank for disinfection, and the high-pressure water supply pump is input into the tap water pipeline, including the following steps:

[0031] (1) Ultraviolet sterilization is carried out before sending into the clear water pool; the ultraviolet intensity is not lower than 90μW / cm 2 , the ultraviolet wavelength range is 253-257nm and 184.9m, and the flow rate of sterilized water after ultraviolet light is 5L / s. The power of the device that generates ultraviolet light is not less than 30W, and the intensity of 253.7nm ultraviolet radiation is: ≥90Uw / cm. The 184.9nm ultraviolet rays can generate ozone to disinfect and sterilize water.

[0032] (2) After entering the clear water pool after ultraviolet sterilization, add chlorine dioxide and chloramine, and a...

Abstract

The invention discloses a treatment process for disinfection by-products of drinking water. The treatment process comprises the following steps: extracting a water source to a water plant; coagulating, settling, filtering, sterilizing with ultraviolet rays, feeding into a clean water tank and adding chlorine dioxide and chloramines; adding polyferric sulfate and disinfecting; inputting to an air-blowing separation tank for aerating, blowing and separating; filtering with activated carbon; and inputting into a running water pipeline by a water pump under high pressure. According to the treatment process, the organic matters in water are treated before chlorination, the precursor of the disinfection by-products is removed, the generation of the chlorination by-products is controlled, and the disinfection by-products in water are cleaned again after the chlorination and the DBPs volume is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of drinking water disinfection, in particular to a treatment process for drinking water disinfection by-products. Background technique [0002] Drinking water disinfection is the greatest progress that human beings have made in the field of public health. The main purpose is to control the pathogenic bacteria in the water and make the water quality meet the health requirements of human beings. However, in the process of disinfection of drinking water, in addition to the role of disinfection and sterilization, the disinfectant will also undergo substitution or addition reactions with natural organic matter, bromide, iodide, etc. in the water to form a disinfection agent represented by halogenated organic matter. By-products (DBPs), and DBPs have been proven to be teratogenic, mutagenic and carcinogenic, which seriously threaten human health. In order to ensure the safety of drinking water, the control of DBPs...
