Pacakge underground mining sewage wastewater treatment plant 

Hotels, restaurants, nursing homes, schools, troops, mining, building, factory of life such as sewage and industrial organic wastewater, similar to the processing.

Characteristic features:
1.The aeration biological fluidized bed as the main treatment process, the built-in stereo cylindrical hollow packing, specific surface area is big, can maintain a higher per unit volume of the microbial biomass, and microbial activity is good, can quickly remove organic pollutants.
2.Stereo cylindrical hollow packing keep the independent and oxygen bacteria coexistence of microbial environment, with a "simultaneous nitrification and denitrification" nitrogen function, ammonia nitrogen lower than ordinary water contact oxidation process.
3.The sediment basins filtration ponds alternative second pond, the filter medium for low density materials, dirt intercept volume is high, outlet water quality good.
4.Equipment can be ploughed back: basic don't cover surface area, no houses, heat preservation, the surface can go green car.
5.Management and maintenance easy.
6.For minor impact on the environment.

Process description:
WSZ series equipment is mainly used for sewage and similar industries organic wastewater treatment, and a aeration biological fluidized bed instead of the conventional of biological contact oxidation process and the efficient filter, has the cover an area of an area small, investment is low, the removal rate higher notable features. The water by 100-250 BOD5 mg/l plan, water more than 20 mg/l to design.

Technology introduction:
A, the necessary pretreatment parts
1, heavy sand traps
The pool of equipment is mainly is to strengthen the pretreatment function, its function has the following three aspects: one is a larger share of the inorganic particles precipitate impurities, facilitate sediments of cleaning, extend the follow-up regulation ponds of effective volume; 2 it is through the hydrolysis acidification,, the organic wastewater to solid and not easily biodegradable organic matter into small molecular soluble organic, and facilitate the follow-up biological treatment, shorten the biochemical time, improve the removal efficiency; 3 it is to lie between water and oil slick except scum, reduce the follow-up processing the load. The pool setting two way baffle, will sink sand pool is divided into three squares. The flow holes are H pipe, tube velocity and low, and can be effectively every except floating oil and scum.
2, regulation ponds
Because water water quality and quantity, fluctuation range is very large, so set up regulation ponds to adjust water, water quality, according to the normal for equipment rated flow processing provided protection.

Second, sewage treatment equipment parts
1, sewage pump
Used to improve sewage, design USES diving type sewage pump, so it is not the need to build pump room, and at the same time, no noise. The pump selection has anti-clogging tear function, can effective improve sewage and not be jammed, prolong the life. Sewage pump equipped with radio 2, a with a ready. Sewage pump by liquid level control, and by microcomputer control cabinet program run by the regulation.
2, the aeration biological fluidized bed
Aeration biological fluidized bed is a new type of aerobic treating method, the pool with stereoscopic cylindrical hollow packing for the carrier filling. Through the aeration make sewage to certain velocity and flow to make the carrier in fluidized state. Sewage in the biochemical pool circulate constantly, in order to make the packing 16 to 20 times (with the unit volume), so in the pool can keep the higher biomass, achieve high speed the purpose of organic pollutant removal. At the same time because its packing special structure, the internal biological and oxygen state, so has the good synchronization the phosphating nitrogen effect greatly improve equipment of ammonia nitrogen removal.
Through the method of microbe treatment to reduce pollution index to reuse degree, is the common international, is also the most economic a treatment. To ensure that the more excellent outlet water quality, can be in aeration biological fluidized bed level after dosing flocculating agent, strengthen the chemical flocculation effect.

3, precipitation filtration ponds
Water flows into traps the fluidized bed, fall off in biological membrane and by tiny suspended solids. The pool precipitation and the filter set in a body, the processing water into the center for first canister spate separation, into foam filter layer filter. Filtration ponds with foam filter in the filter material, foam filter bead size 2-3 mm, water drainage cap by the water. Pool setting a reverse wash suction pump, the wash water into water sink sand pool processing. Design filter filter speed of 2 m/h.
The filter has SS large flow, filtering effect is good, simple operation and other characteristics, instead of the conventional technology of the second pond, greatly reduced the equipment volume, and make water get effective guarantee.
4, sterilization tank
Selection of organic chlorine, dichloroisocyanuric disinfectant trichloroisocyanuric acid. Direct contact with the way the dissolved, because the chlorine piece has the characteristics of saturated dissolved, and therefore, can according to the change of water treatment and automatically change the dosage. Sterilization tank outlet direct emissions.
If you need the chlorine dioxide disinfection, can be separately designed
