Abstract

The invention relates to a composite water purifying agent and a preparation method thereof. The water purifying agent contains activated carbon, diatomite, polymeric aluminum, polyacrylamide and polyethylene glycol. The preparation method comprises the following steps: 1, mixing the diatomite with the activated carbon; 2, adding deionized water, and uniformly stirring; 3, after mixing the polyacrylamide with the polyethylene glycol and uniformly stirring, adding into the water solution of the activated carbon and diatomite mixture; 4, dissolving the polymeric aluminum into the deionized water, then slowly adding into a mixture obtained in the step 3 for stirring to obtain a composite water purifying agent semi-finished product; 5, removing water in the composite water purifying agent semi-finished product to obtain the composite water purifying agent. The water purifying agent prepared according to the method combines the diatomite with the activated carbon, retains the adsorption capacity to organic small molecules in water of the activated carbon, and can also adsorb macromolecular organic matters in water due to the addition of the diatomite. The polyacrylamide and the polymeric aluminum can quickly flocculate granular dregs to achieve the action of purifying water.

Description

technical field [0001] The invention relates to a water purifier in the field of water purification, in particular to a composite water purifier and a preparation method thereof. Background technique [0002] At present, with the rapid advancement of my country's industrialization process, environmental pollution, especially water pollution, is becoming more and more serious, seriously affecting people's health and living environment. Coagulation treatment of industrial wastewater and urban sewage with water purifier is one of the most commonly used methods in water treatment, and it is also an important means to eliminate pollution and protect the environment. [0003] In recent years, extensive investigation and research have been carried out abroad on the endocrine disrupting activity of environmental chemicals. A large number of animal epidemiological data show that many environmental chemicals can interfere with the endocrine function of animals, which are clinically c...
