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

Example

[0029] Example 1

[0030] The process for treating drinking water disinfection by-products of the present invention extracts the water source to a water plant, and then coagulates, settles, filters, and sends it to a clean water tank for disinfection, and is fed into a tap water pipeline by a water pump under high pressure, including the following steps:

[0031] (1) Carry out ultraviolet sterilization before sending into the clean water tank; the ultraviolet intensity is not less than 90μW / cm 2 , The ultraviolet wavelength range is 253~257nm and 184.9m, and the water flow rate is 5L / s after sterilization by ultraviolet lamp. The power of the device that generates ultraviolet rays is not less than 30W, and the intensity of ultraviolet rays radiating 253.7nm is: ≥90Uw / cm. Ultraviolet rays of 184.9nm can produce ozone to sterilize water.

[0032] (2) After entering the clean water tank after ultraviolet sterilization, add chlorine dioxide and chloramine, and add polyferric sulfate at ...

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...
