Problems solved by technology

Although polyacrylamide plays a very important role in water treatment, the existing methods generally use a single polyacrylamide, which is expensive and inhibits its wider application
[0005] Secondly, there are physical, chemical, biological, comprehensive and other methods to deal with the pollution of water resources, but most of the physical methods have problems of poor treatment effect and unstable treatment rate; the cost of biological methods is too high to be popularized and used; Chemical methods are used to treat sewage, but the existing sewage treatment agents have secondary pollution problems in their reagent components, which will also have a certain impact on the environment

Embodiment Construction

[0013] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any way except mutually exclusive features and / or steps.

[0014] Any feature disclosed in this specification (including any accompanying claims and abstract), unless expressly stated otherwise, may be replaced by other equivalent or alternative features serving a similar purpose. That is, unless expressly stated otherwise, each feature is but one example of a series of equivalent or similar features.

[0015] A new type of sewage treatment agent is prepared by the following parts by weight: 20-30 parts of polyacrylamide, 12-15 parts of polyethyleneimine, 20-25 parts of activated carbon, 2-5 parts of titanium dioxide, dodecylsilyl group 5 to 10 parts of sodium sulfate.

[0016] Further, it also includes 20-30 parts of bentonite and 10-20 parts of polyaluminum ferric chloride.

[0017] Further, 25 parts of the polyacrylamide, 13 parts of polyethyleneimine, 2...

Abstract

The invention relates to a novel sewage treatment agent. The novel sewage treatment agent is prepared from, by weight, 20-30 parts of polyacrylamide, 12-15 parts of polyethylene imine, 20-25 parts of activated carbon, 2-5 parts of titanium dioxide and 5-10 parts of sodium dodecyl sulfate. By controlling and changing the addition sequence of inorganic polymer and organic polymer substances with different functional groups and the conditions under which reactions happen or not happen in the compounding process, good form distribution and stability of the components are kept before the components are added, and very quick form transformation and efficient coagulation and flocculation are achieved after the components are added.

Description

technical field [0001] The present invention relates to a novel sewage treatment agent. Background technique [0002] Due to population growth and economic development, the over-exploitation and unreasonable development and utilization of resources have resulted in a series of problems affecting the quality of resources, which have directly threatened the survival of us and future generations. [0003] my country is also faced with these problems. my country is a country with a shortage of water resources. How to alleviate the problems of water shortage and pollution has become an urgent issue. [0004] There are many methods of sewage treatment, but the common ones are physical method and chemical method. Among them, chemical treatment of sewage is the most used by people. Polyacrylamide is the most commonly used water treatment agent in chemical methods. The application of polyacrylamide in the water treatment industry mainly includes three aspects: raw water treatment,...
