According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., and domestic sewage is sewage produced by daily life. It refers to a complex mixture of various forms of inorganic and organic materials, including: 1 floating and suspended solid particles; 2 glue Shape and gel-like diffuser; 3 pure solution.
According to the nature of water pollution, there are two types of water pollution: one is natural pollution; the other is artificial pollution. At present, the most harmful to the water body is man-made pollution. Water pollution can be divided into chemical pollution, physical pollution and biological pollution according to different pollution impurities. The main pollutants are: (1) industrial wastewater discharged without treatment; (2) domestic sewage discharged without treatment; (3) farmland sewage using a large amount of chemical fertilizers, pesticides and herbicides; (4) stacked in the river Industrial waste and domestic garbage; (5) soil erosion; (6) mine sewage.
There are many methods for treating sewage, which can be generally classified into physical methods, chemical methods, and biological methods.
Sewage treatment plant: Some people surveyed more than 100 large treatment plants, half of which were sun-baked, and there were insufficient funds, high cost and low efficiency. The general efficiency was less than 70%, and the low was only 40%.
Sewage treatment cost energy consumption: basically high energy consumption / low efficiency.
At present, urban domestic sewage discharge is the main source of urban water pollution in China. Urban domestic sewage treatment is the top priority of current and future urban water conservation and urban water environmental protection work, which requires us to treat the construction of domestic sewage facilities. The important content of urban infrastructure is catching up, and it is an urgent matter.
The direct use of sewage is now: With the advancement of human society, the development of science and technology, the direct use of sewage has become possible, using sewage source heat pump system to utilize urban sewage.
The so-called raw sewage directly discharges untreated living or industrial wastewater in the city. At this stage, the use of raw sewage directly enters the sewage source heat pump system for heat exchange, and consumes a small amount of electricity to heat indoor heating of urban buildings. There are several technical difficulties in wastewater reuse that need to be overcome: blockage, corrosion, and heat transfer efficiency.
The sewage source heat pump system is composed of a sewage heat exchanger and a sewage source heat pump. After the urban raw sewage directly enters the sewage heat exchanger for heat exchange, the heat exchanged is transferred to the indoor by the heat pump inside the sewage source heat pump.
The advantages of recycling the city's primary sewage are: energy saving and environmental protection, no pollution.
