Problems solved by technology

For high-concentration inorganic salt sewage, since the salt is not easy to volatilize, if a single-effect evaporator is used to recover inorganic salt by evaporating water, it will consume a lot of energy, resulting in the problem of high sewage treatment costs
[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 discloses a polymer nanoscale sewage treatment agent and a treatment method and relates to the technical field of wastewater treatment. The polymer nanoscale sewage treatment agent comprises the following components in percentage by weight: 20-25 parts of polyvinylidene fluoride, 10-15 parts of DMAC solvent, 3-8 parts of PVP pore forming agent, 3-6 parts of nanometer titanium dioxide, 5-10 parts of nanometer alumina fibers and the like. The invention provides the polymer nanoscale sewage treatment agent and the treatment method. By using the method and adding the agent to carry out multistage sewage treatment for domestic sewage, the effect is obvious, and the cyclic utilization of a water resource is realized.

Description

field of invention [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a polymer nanometer sewage treatment agent and a domestic sewage treatment method. Background technique [0002] There are many kinds of chemical sewage, most of which are highly toxic and difficult to purify. They have a certain accumulation effect in organisms and have obvious aerobic properties in water bodies, which can easily deteriorate water quality. If they are discharged directly, they will inevitably bring about serious environmental pollution problems. Therefore, in the chemical production process, the sewage treatment process has become an indispensable operation unit. For high-concentration inorganic salt sewage, since the salt is not easy to volatilize, if a single-effect evaporator is used to recover inorganic salt by evaporating water, it will consume a lot of energy, resulting in high sewage treatment costs. [0003] The existing natu...
