Abstract

The invention relates to a wastewater and sewage composite water quality treatment material, which is prepared by the following method: S1, performing zeolite pretreatment; s2, preparing zeolite loaded nano titanium dioxide; s3, preparing modified bentonite; and S4, weighing the following components in percentage by mass: 3-5% of pullulan polysaccharide, 5-10% of the zeolite loaded nano titanium dioxide, and the balance of modified bentonite, and uniformly mixing to obtain the wastewater and sewage composite water quality treatment material. The wastewater and sewage composite water quality treatment material provided by the invention has the characteristics of simple preparation method, strong operability, high treatment effect and the like, and can effectively improve the treatment / purification capability of wastewater / wastewater in the prior art.

Description

technical field [0001] The invention relates to a wastewater and sewage composite water quality treatment material. Background technique [0002] In recent years, water pollution is one of the pollution problems that people pay the most attention to. my country has given high attention to water pollution control, and more and more sewage plants have been built. Sludge, as solid or semi-solid waste produced in the water treatment process of urban sewage treatment plants, increases with the increase of sewage treatment volume. In 2015, the discharge of urban domestic sewage reached 53.52 billion tons, accounting for 72.8% of the total wastewater discharge, and the annual discharge of sludge was about 42.82 million tons (based on a moisture content of 80%). With the improvement of living standards, people have higher and higher requirements for water quality, which increases the treatment rate and depth of sewage, and the total amount of sludge produced is increasing at a rate...
