Embodiment 1

[0028] A method for deep purification of waste water and sewage, which uses composite water quality treatment materials to carry out deep purification treatment of waste water or sewage. The specific process is: adding composite water quality treatment materials to waste water or sewage, stirring, static sedimentation, and centrifugal separation After that, the deep purification is completed;

[0029] The composite water quality treatment material is prepared by the following method:

[0030] S1 zeolite pretreatment: Stir the zeolite in hydrochloric acid solution, let it stand, and filter; boil the filtered zeolite in distilled water, wash it with distilled water, and finally put the zeolite in an oven to bake, and cool it for later use ;

[0031] S2 Preparation of zeolite-supported nano-titanium dioxide: Add 10 g of pretreated zeolite and 5 g of coupling agent to 200 mL of titanium dioxide sol, filter out the sieve after ultrasonication and let it stand, dry it at a constant...

Abstract

The invention relates to a deep purification treatment method of wastewater and sewage, namely, the wastewater or sewage is deeply purified by adopting a composite water quality treatment material, and the specific process is as follows: the composite water quality treatment material is added into the wastewater or sewage, and the deep purification is completed after stirring, standing for precipitation and centrifugal separation treatment. The deep purification treatment method 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 the sewage / wastewater in the prior art.

Description

technical field [0001] The invention relates to a method for deep purification of wastewater and sewage. 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 of 10% per...
