Problems solved by technology

The current sewage purification treatment technology is mainly to introduce sewage into sewage treatment facilities, and carry out purification treatment through flocculation, sedimentation, separation and other processes, but the above-mentioned polluted water bodies cannot be treated by sewage treatment facilities due to limited conditions or huge quantities
[0003] At present, in the known technical field, the deodorization effect of domestic sewage is mainly achieved by adding nano-silver ions or quaternary ammonium salt ions, but the application of the above-mentioned method has a large safety hazard, and if there is any residue, it will bring harm to the human body
At present, there is no inquiry about the sewage antibacterial deodorant made of tea as a natural functional additive

Abstract

The invention discloses an antibacterial deodorant for sewage. The antibacterial deodorant is prepared from, by weight, 200 parts of acrylic acid, 65-80 parts of sodium hydroxide, 200-300 parts of deionized water, 0.02-2 parts of initial cross-linking agent, 10-200 parts of tea powder or tea extract, 0.05-0.6 part of initiator, 0-5 parts of dispersing agent and 0.2-4 parts of compound cross-linking agent. The antibacterial deodorant for the sewage can be widely used in sanitary absorbent articles, the natural food-grade tea and the extract thereof are selected as function materials, compared with other chemical antibacterial agents, the antibacterial deodorant has the advantages of being good in compatibility, high in safety and the like, excellent antibacterial and deodorant effects are achieved, and the significant inhibiting effect on bacteria such as escherichia coli, staphylococcus aureus and candida is achieved. According to the antibacterial deodorant for the sewage, the raw materials are easy to obtain, the cost is low, the effect is significant, and huge economic benefit, social benefit and environmental benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage antibacterial and deodorant. Background technique [0002] With the increase of urban population and the development of industrial and agricultural production, the amount of sewage discharge continues to increase, and water pollution damages the ecological environment, seriously threatening human survival and health. Therefore, the problem of sewage purification treatment has been paid more and more attention. However, due to the constraints of economic conditions and many objective conditions, only part of the urban and rural sewage has been treated, and there is still a lot of sewage, especially some domestic sewage, which cannot enter the sewage treatment plant for purification treatment, and is directly discharged into ditches and rivers, forming a large number of sewage rivers, smelly Ditch phenomenon; non-point source pollutants such as a large amount of ...
