Problems solved by technology

[0004] At present, the common phthalate esters (PAEs) pollutants in the water body of the water source catchment mainly include dibutyl phthalate (DBP) and dioctyl phthalate (DOP). The commonly used water purification process is Chlorination, flocculation and sedimentation and filtration have been carried out on the raw water, but according to the determination of the concentration of DBP and DOP in the water sample after each unit treatment, this water purification process has obvious removal effect on the above two PAEs, but the factory water DBP is still in a state of exceeding the standard, so it is necessary to further explore new methods to eliminate phthalate pollutants in the water body of the water source catchment area. Physical methods can no longer meet the needs of environmental protection. It is necessary to combine biological, chemical and physical methods. In order to achieve a satisfactory processing effect

Embodiment 1

[0023] Embodiment 1: a kind of method of removing phthalates pollutants in the water body of water catchment area, described method comprises the following steps:

[0024] (1) Pump the water in the catchment area into the sedimentation tank through the water pump. The bottom of the sedimentation tank is designed in a conical shape, which can make the sediment settle by gravity. The conical design can make the sediment gather quickly and facilitate the discharge of solids. Add The precipitant is precipitated, and the sediment is discharged from the bottom of the sedimentation tank through the sludge discharge valve with filtering function, and then the obtained supernatant is collected;

[0025] (2) filtering the supernatant collected in step (1) through an oscillating filter membrane, the oscillating effect can enhance the suspension effect of solid particles, so that the suspended matter therein can be better removed to obtain a filtrate;

[0026] (3) Pass the filtrate that s...

Abstract

The invention provides a method for removing phthalate contaminants in a water body of a source water gathering area. The method comprises the following steps that 1, water in the water gathering area is precipitated through a precipitation pool, and supernatant liquid is obtained through collection; 2, the supernatant liquid is filtered through an oscillation filter membrane to remove suspended substances in the supernatant liquid, and filtrate is obtained; 3, the filtrate is introduced into a sterilization pipeline, and after an oxidizing agent is added, high-pressure mercury lamp light source irradiating sterilization is conducted; 4, the water obtained after sterilization is subjected to biochemical adsorption through a biological resin adsorption tower, biological resin is subjected to recycling and eluting treatment, and the water obtained after adsorption is introduced into a safe water source reserve pool. According to the method, the phthalate contaminants in the water body of the source water gathering area can be effectively removed, by isolating the safe water source reserve pool, the condition that a water source is subjected to secondary contamination can be avoided, state isolation can be conducted on the water body of the water source water gathering area, and it is guaranteed that the water source not only can meet the environmental protection requirement but also can meet the safe application requirement.

Description

technical field [0001] The invention relates to the technical field of water quality purification treatment, in particular to a method for removing phthalate pollutants in water bodies in water source catchment areas. Background technique [0002] Phthalate Esters (hereinafter referred to as PAEs) are artificially synthesized organic compounds with the largest production volume and wide application range in the world. They can be used as plasticizers, solvents, and auxiliary agents. In insect repellants, food packaging materials, detergents, lubricants, paints, coatings and other products. With the continuous development of industrial and agricultural production and the widespread use of plastic products. [0003] Phthalate organic compounds are widely used in plastic products, especially in polyvinyl chloride (PVC), which occupies a very high proportion. Phthalate esters in plastics can migrate from plastics to the external environment over time, causing pollution to the ...
