Background
Sewage treatment refers to the process of purifying sewage to meet the water quality requirement of being discharged into a certain water body or reused. The sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscapes, medical treatment, catering and the like.
Sewage treatment is generally classified into production sewage treatment and domestic sewage treatment according to sewage sources. The production sewage includes industrial sewage, agricultural sewage, medical sewage, etc., and the domestic sewage is sewage produced in daily life, and refers to a complex mixture of various forms of inorganic matters and organic matters, including: (1) floating and suspended solid particles of size; (2) gelatinous and gelatinous diffusers; (3) pure solution.
The water pollution is classified into two categories according to the nature of the water pollution: one type is natural pollution; the other type is artificial pollution, and the current hazard to water is great. Water pollution can be largely classified into three categories of chemical pollution, physical pollution and biological pollution according to the difference of pollution impurities. The pollutants are mainly as follows: (1) untreated industrial wastewater; (2) untreated domestic sewage; (3) A great deal of farmland sewage using chemical fertilizers, pesticides and herbicides; (4) industrial waste and household garbage piled up on river sides; (5) water and soil loss; (6) mine sewage.
In the field of aerospace environment protection, a aerospace nano modified filter material is generally adopted as a main means for sewage environment treatment, and the core of the method is that high-frequency waves are used as energy sources, water is used as an initiator, cavitation effect generated when the high-frequency waves are transmitted in the water is utilized and accompanied by mechanical effect, natural ores are broken through hydrogen bonds and chemical bonds under the action of the cavitation effect, atomic ring atomic groups of unpaired electrons are separated, free radicals induced in a cracking groove are not immediately combined to generate new substances, then the new substances are removed by the waves, and the natural ores are modified and reamed. Compared with the traditional rubbing, grinding and drilling technology, the technology is a nano filter material produced by carrying out nano-scale processing on raw materials on a microscopic level.
