Problems solved by technology

[0003] The existing natural energy mainly includes water energy, wind energy, solar energy, tidal energy, biomass energy, etc. Among them, water resources occupy most of the earth's area and are one of the energy sources we rely on for survival. With the continuous improvement of living standards There is more and more domestic sewage, but the treatment capacity of wastewater cannot keep up with the rapid expansion of water consumption, and cannot effectively realize the scientific recycling of water resources

Abstract

The invention relates to a nano polymer hydroxymethyl chitosan domestic sewage treatment agent and a treatment method, and relates to the technical field of wastewater treatment. The sewage treatmentagent comprises the following components in parts by weight: 15-25 parts of hydroxymethyl chitosan, 5-10 parts of sodium alginate, 5-10 parts of porous sponge graphene, 25-30 parts of furfural acetoneformaldehyde resin, 15-20 parts of modified alginate based fibers, and the like. According to the modified chitosan-based solution provided by the invention, the fibers are adopted as carriers for forming a modified chitosan-based solution, nano titanium dioxide is grafted on the surface for increasing the surface area ratio of the fibers, inorganic cationic poly silicon fluoride is used on the outer layer with a large surface area, and an electrostatic adsorption is carried out with the organic anionic polyalkene amide, so that the stability and the firmness of the material are ensured on the basis of the large surface area ratio. Through the method, the agent is added for carrying out multi-stage sewage treatment on the domestic sewage, the effect is obvious, and the recycling of waterresources is realized.

Description

field of invention [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a nano-polymer hydroxymethyl chitosan domestic sewage treatment agent and a domestic sewage treatment method. Background technique [0002] With the increase of sewage treatment rate and treatment depth, sludge discharge is increasing at a rate of more than 10-15% per year, but supporting sludge treatment and disposal has not made great progress. Due to technical and policy reasons, most domestic urban sewage sludge is disposed of by landfill without harmless treatment, and the secondary pollution of sludge is extremely serious. The massive landfilling of sludge with high moisture content leads to the occupation of valuable land resources, so that many cities cannot find landfills. Sludge leachate has become a source of groundwater pollution in many areas, landfills have become mosquito breeding grounds, and landfill gas has become a source of atmosph...
