Description

Domestic sewage collecting and treating facility

Technical Field

The invention relates to a sewage treatment facility, in particular to a domestic sewage collection and treatment facility.

Background

Ecological civilization construction is one of the important topics in the present generation. The Yangtze river economic zone needs to be protected and developed greatly. Yangtze river, yellow river, etc. all have pollution of different degrees. One important aspect of pollution prevention and control is sewage treatment. The urban domestic sewage is an important component of sewage, has large volume and is directly discharged to pollute the water environment. The bio-sewage may contain solid impurities, liquid impurities and gaseous impurities, various microorganisms, various ions, water, and the like. How to separate water molecules from other impurities in domestic sewage? If the water purifier is used for drinking, the water purifier is very expensive and too high in cost, and is suitable for scientific research and drinking water manufacture. How to realize the purification of domestic sewage and then discharge the domestic sewage into the environment with the least cost? In the prior art, urban domestic sewage collection and treatment facilities are lacked, impurities and water are difficult to separate, and dirt is difficult to collect.

In common words: the running water is not rotten. The size of the water molecule is about 0.4 nanometer, and the size of small molecules such as ammonium ions, sodium ions, chloride ions and the like is not greatly different from the water molecule. The protein is a biological functional molecule, the molecular weight of the protein is 6000 to millions, and the average diameter of the globular protein is about 10 nanometers. The viral particles have a size, for example, the size of a new coronavirus particle is about 100 nm. Bacteria vary in shape, for example, unicoccus have a reference diameter of about 1000 nanometers, and for example, E.coli cells have a size of about 500 nanometers by 2000 nanometers. Mold spores, yeast cells, etc. are about 5000 nanometers in size. The semipermeable membrane is permeable to water molecules and small molecular ions, but impermeable to proteins, but is fragile, expensive, slow in dialysis, and suitable for hemodialysis and the like. Volcanic eruption, gas and solid are mixed together to form magma, after cooling, the gas is evaporated, the solid is cooled to form volcanic rock with the same honeycomb shape, and the volcanic rock has certain strength and good water permeability and can be used as a new material for filtering rough impurities in sewage. If the ceramic is not subjected to waterproof polishing, the size of the gaps is about 2000 nm, fungal cells and substances larger than the fungal cells can be blocked, the strength of the ceramic is high, a certain adsorption effect is achieved, and the gaps of the porous ceramic are slightly larger than those of the ceramic. Sand is characterized by its ability to allow water to leak, but prevent water from flowing too quickly, and it also acts as a substrate for the plant roots to settle. The vegetation can absorb small molecular nutrients in the water body, such as ammonium ions and the like. Volcanic rock, ceramic, sand and the like all have certain adsorption effect.
