Embodiment Construction

[0013] See the table below, a method for removing the environmental hormone dimethyl phthalate in source water, comprising the following steps:

[0014] First, analyze the content of the environmental hormone dimethyl phthalate in the source water to be treated;

[0015] Secondly, according to the content of the environmental hormone dimethyl phthalate in the source water, the reaction amount of the polydimethyldiallylammonium chloride flocculant is calculated, and the polydimethyldiallyl ammonium chloride flocculant contained in the source water The amount of ammonium chloride is 0.10-20mg / L.

[0016] Third, the removal process is:

[0017] (1) The source water is transported to the reactor, and the flocculant polydimethyldiallylammonium chloride is added to the reactor through the dosing pipe according to the ratio described in Table 1; The water and the flocculant are fully stirred, and the flocculant is fully mixed with the source water by rapid stirring first (stirring ...

Abstract

The invention provides a method for removing environment hormone dimethyl phthalate in water body; the treated water is mainly used for water supplying in towns and cities and being stored in water plants; the method comprises the following steps: (1) flocculating agent-poly-dimethyl diallyl ammonium chloride is added in a reactor with source water, and the source water and the flocculating agent are completely stirred uniformly. (2) The source water treated in the step (1) is placed still for a while, and then the source water is discharged for subsequent treatment after carrying out flocculating settling. In the invention, the poly-dimethyl diallyl ammonium chloride is used as the flocculating agent to adsorb dimethyl phthalate in source water, and then the content of the dimethyl phthalate is effectively reduced through flocculating settling, so as to greatly improve the municipal engineering water supplying safety and hygienic quality. The method has the characteristics of convenient operation, low treating cost, easily-controlled conditions and stable treatment effect and can remove more than 60 percent of dimethyl phthalate organic matters in source water.

Description

technical field [0001] The invention relates to a method for removing the environmental hormone dimethyl phthalate in source water. It is mainly used for advanced treatment of urban water supply and effectively reduces the content of dimethyl phthalate in water source. Background technique [0002] In recent years, with the development of industrial and agricultural production, especially the rapid development of organic synthetic chemical industry, petrochemical industry, pesticide and insecticide industries, more and more organic pollutants have entered water bodies, resulting in a sharp deterioration of drinking water quality. Drinking water safety has become one of the main factors threatening human health. As urban water sources, many lakes, rivers, and reservoirs are seriously polluted, and persistent toxic and harmful substances are constantly being discovered. Dimethyl phthalate is one of the most important trace organic pollutants. Due to phthalic acid The content...
