Abstract

The invention provides a sewage treatment agent as well as a preparation method and application thereof, and relates to the technical field of sewage treatment, and the sewage treatment agent comprises a component A and a component B. The component A is prepared from the following raw materials in parts by weight: 20-40 parts of biologically modified zeolite powder and 10-23 parts of non-ionic polyacrylamide; the component B is prepared from the following raw materials in parts by weight: 8-18 parts of carbon-doped modified titanium dioxide, 5-10 parts of polyaluminum chloride, 3-8 parts of amino trimethylene phosphonic acid and 8-15 parts of silicate,. The sewage treatment agent has an excellent removal effect on dyes, organic pollutants, ammonia nitrogen, suspended solids, total phosphorus, heavy metals and the like in sewage, the treated wastewater can reach the first-grade discharge standard, and the preparation method is simple and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment agent and its preparation method and application. Background technique [0002] Water resources are one of the important resources for the sustainable development of modern society. The protection of water environment and the sustainable utilization of water resources are the primary environmental resource issues in our country at present. With the rapid increase of economic development and population in the world, the shortage of water resources has become an urgent problem to be solved. At present, many water-scarce countries in the world regard the recycling of water resources as an important strategy to alleviate the shortage of water resources. At the same time, they also control the use of fresh water, which solves the contradiction between water supply and water use to a certain extent. It has obvious social, environmental and economic benefits...
