Problems solved by technology

[0005] The inventors of the present application found by searching the prior art that although a single metal active substance can reduce the pollutant index in the sewage, the post-treatment process is difficult and easily causes secondary pollution; even if there are composite materials, the stability Poor, resulting in short actual use time and need to be replaced regularly, which increases the cost on the one hand, and increases the difficulty of handling on the other hand

Abstract

The invention discloses a preparation method of an environment-friendly river and lake water treatment composition. The method comprises the following steps: weighing a carrier and a metal active matter according to a mass ratio of 1: (0.1-0.5), uniformly mixing, and calcining at 1000-1500 DEG C for 6-10 hours to obtain a first composition; adding a thermoplastic polymer and graft-modified polyolefin according to a mass ratio of 1: (0.5-1), uniformly mixing, calcining at 200-600 DEG C for 2-4 hours, cooling to 80-100 DEG C, adding 2, 2 '-methylene bis-(4, 6-di-tert-butylphenyl) aluminum phosphate and an organic acid, fully mixing, and continuously reacting for 30-60 minutes to obtain a second composition; and selecting a flaky solid material as a matrix, uniformly mixing and stirring the first composition, the second composition, an adhesive and a stabilizer, coating the surface of the matrix with the mixture, airing, carrying out drying in a drying oven at 40-60 DEG C overnight, and taking out a product to obtain the environment-friendly river and lake water treatment composition. The river and lake water treatment composition can effectively remove pollutants in river and lake water.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an environment-friendly river and lake water treatment composition and a preparation method thereof. Background technique [0002] my country is one of the countries with serious water shortage and pollution. From the national situation, the water shortage in various industries is serious at present, which has caused serious economic losses and social and environmental problems. Water conservation, sewage treatment and development of new water sources are equally important. Vigorously developing water treatment compositions plays an important role in saving water and treating sewage. At present, due to human life activities and industrial production activities, the pollution of river and lake water is becoming more and more serious. Due to the poor fluidity of river and lake water, its treatment is relatively difficult. [0003] The water treatment compositi...
