There are a lot of organic matters in the sewage of railway station, such as cellulose, starch, sugar, fat and protein. It also contains pathogens, viruses and parasitic eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium, etc. It is characterized by high content of nitrogen, sulfur and phosphorus. Under the action of anaerobic bacteria, it is easy to produce malodorous substances.

organic compound

Organic compounds are referred to as organic compounds. Carbon containing compounds (except carbon monoxide, carbon dioxide, carbonic acid, carbonate, bicarbonate, metal carbide, cyanide, thiocyanate, etc.) or hydrocarbons and their derivatives. Inorganic compounds usually refer to compounds without carbon elements, but a few compounds containing carbon elements, such as carbon dioxide, carbonic acid, carbon monoxide, carbonate, etc., do not have the nature of organic matter, so such substances also belong to inorganic substances. In a word, all organic compounds are carbonaceous compounds, but carbonaceous compounds are not necessarily organic compounds.
 

sewage

Definition: the general term of water discharged in production and living activities. Sewage: the water that has lost its original function is called sewage. Sewage is due to the water mixed with new substances or because of changes in external conditions, resulting in water deterioration, can not continue to maintain the original use function.

Working principle of sewage treatment equipment

The railway station sewage mainly removes organic pollutants and ammonia nitrogen, which mainly depends on the Ao biological treatment process in the equipment. At this time, the concentration of organic matter in the pool is higher than that of the organic matter, so the concentration of organic matter in the pool is still in a high level, so the microbial load is still in a certain degree.

In order to further oxidize and decompose organic matter, and nitrification can proceed smoothly under carbonization, aerobic biological oxidation tank with low organic load is set at O level. There are mainly aerobic microorganisms and autotoxic nitrifying bacteria in the o-class pool. Among them, aerobic microorganisms decompose organic matter into CO2 and H2O; autotrophic (nitrifying bacteria) uses inorganic carbon produced by organic matter decomposition or CO2 in the air as nutrient source to convert NH3-N in sewage into no-2-n and no-3-n. part of the o-class pool is returned to the pool to provide electron acceptor for the pool, and final nitrogen pollution is achieved through denitrification.

 Equipment piping

The sewage treatment equipment of railway station has the following characteristics:

(1) it is not easy to produce sludge bulking, especially when the sewage enters the biochemical treatment device, it keeps in the anaerobic state, which reduces the sv1 (sludge index) and saves the power cost of aeration.

(2) the structure of the treatment structure is simple, and the equipment cost and operation management cost are also less than those of the continuous type.

(3) in most cases, the flow regulating tank is not needed.

(4) the volume of aeration tank is smaller than that of continuous tank.

(5) if the operation is proper, the water quality can be better than that of continuous treatment, and the purpose of biological nitrogen and phosphorus removal in single tank can be realized.
