Problems solved by technology

Although my country's research in this area has made some progress in recent years, it is still far from meeting the actual needs.
In addition to the organic cationic flocculants produced by the Mannich reaction of polyacrylamide, there are almost no water-soluble organic cationic polymer flocculants that can be truly industrialized and have industrial potential, and the organic cationic flocculants produced by the Mannich reaction are due to the single Toxicity of the body, can not be used for water treatment, its development is limited

Embodiment 1

[0034] Embodiment 1: The production method of a compound used for sewage treatment of the present invention adopts the following process steps: its component ratio is calculated in parts by weight:

[0035] 30 parts of concentrated hydrochloric acid were charged into a 5-liter round-bottom three-neck flask and stirred with a mechanical stirrer, and the concentration of concentrated hydrochloric acid was 37.5%. The three-necked flask was cooled to below 5°C with an ice bath, 28 parts of allylamine were added dropwise to the stirring hydrochloric acid to prepare a solution, and the temperature of the solution was kept below 10°C. Add 2 parts of water, stir evenly, add 2 parts of azobis(amidinopropane) dihydrochloride as a 20% aqueous solution, add azobis(amidinopropane) after stirring for 15 hours at 60°C ) 2 parts of dihydrochloride were added as a 20% aqueous solution, when the temperature was kept at 60°C and stirred for 48 hours, cooled to room temperature and added 10 parts...

Abstract

The invention relates to a chemical compound for sewage treatment, which is characterized in that acid is filled in a container and is stirred up; the container is cooled in ice bath; allyl amine is added in the acid which is being stirred up to make into solution; water is added in the solution which is then stirred up evenly; initiator is added in the solution which is then stirred up evenly; more initiator is added in the solution which is then stirred up evenly and cooled to room temperature; water is added in the solution which is then stirred up evenly and filtrated; filtrate is added in organic solvent and is mixed into white solid; the white solid is added in ice water and stirred up until completely dissolving; cross linking agent is added which is reacted in room temperature; water is added in the solution which is then stirred up and filtrated; filter cake is then added in the organic solvent which is then stirred up and filtrated; the chemical compound can be got by vacuumdrying. The chemical compound can increase the quantity of cation, can combine with a great many of anion hydrophilic groups to play the role of flocculation, has low production cost and simple technology, is convenient to be used, can be used for urban sewage treatment, can remove the phosphorus in the sewage effectively, and can improve the efficiency of sewage treatment.

Description

technical field [0001] The invention relates to a compound for sewage treatment, in particular to a cationic polymer, a phosphorus removal compound for sewage treatment, and belongs to the technical field of sewage treatment. Background technique [0002] In the mid-1970s and 1980s, most of the urban sewage treatment processes were traditional activated sludge methods, which mainly aimed to remove chemical oxygen demand (COD), and did not require high nitrogen and phosphorus indicators in the treated effluent. In recent years, with the development of industrial production and the improvement of people's living standards, the amount of industrial sewage and urban domestic sewage is increasing at an alarming rate. These sewage have or are polluting the rivers, rivers and lakes that human beings rely on. , has become one of the reasons that threaten the living environment of human beings, and the treatment of sewage has become one of the most important issues in environmental p...
