Description

with economic and population growth, nature pollution is more and more valued by people, based on summary of domestic sewage treatment equipment operation experience at home and abroad ,combine our company’s scientific achievements and engineering practice, designed a whole set of organic wastewater treatment equipment which can be buried underground, which adopted the advanced technique and manufacturing technology at home and abroad 1n late of 1990s,produed the LHC series of sewage treatment equipment, which main raw material is fiberglass, stainless steel, its main purpose is make the domestic sewage and similar industrial organic sewage to achieve user's emissions standards after disposed by this equipment. This equipment mainly used in treating domestic sewage in Residential area (including villa district), senior hotel ,complex office and various of public hospital buildings, the water quality can achieve national emission standard after treated by the equipment. A full set of equipment can be buried in the ground, is also known as "integrated waste water treatment equipment."
our integrated wastewater treatment equipment adopt international advanced biological treatment processes, set to remove BOD5, COD, NH3-N in one, with the advantage of Technical performance stable and reliable, good treatment effect, save investment, small occupy area, and easy maintenance.

Characteristics
1, lay underground or ground, above the surface can be used as green or other land, no housing and heating, insulation.
2, contact oxidation process are the use of plug-flow bio-contact oxidation, the treatment is better than completely mixed or two series completely mixed biological contact oxidation pool. And small size than the activated sludge tank, the water quality of adaptability, resistance to shock loading performance, effluent quality and stability, does not produce sludge bulking. Pool using the new flexible three-dimensional packing, large surface area, microbial and easy to hang film, stripping, in the same organic load conditions, high removal rate of organic matter, oxygen in the air can increase the solubility in water.
3, biochemical use of biological contact oxidation pool, its relatively low volume loading of filler, microbial oxidation stage in their broken, less sludge production, only three months (90 days) above a row of mud (using suction truck or dehydration cake transport out).
5, fully automatic equipment control systems and electrical equipment failure alarm system, safe and reliable operation, usually does not require expert management generally, only timely maintenance and repair of equipment.

Scope of Application

1. Hotels, restaurants, nursing homes, hospitals.

2. Residential areas, village, town,Villa etc

3. Stations, airports, port terminals and ship.

4. Factories, mines, military, tourist, scenic.

5. All kinds of industrial wastewater similar with domestic sewage.

Technics processing:

The sewage will first flow into equalize tank, its function is equalize sewage volume and quality, make the sewage enter into the integrated sewage treatment equipment by lifting pump.

Aerobic tank, its rely on Autotrophic type bacteria finish treatment, they adopt Organic decomposition producing inorganic carbon source or carbon dioxide in air as nutritional sources, make the ammonia nitrogen in sewage convert into . In first settling tank and aerobic tank all equip padding, the whole Biochemical process rely on many microbes attached on the padding, some effluent water from aerobic tank back flow into equalize tank proceeding internal Circulation, so achieve denitrification purpose, another parts will flow into settling tank, proceeding solid-liquid separation, the effluent water will be discharge.

(1)Equalize tank: reinforced concrete structure, used to homogenize water volume and quality.

(2)First settling tank:the sewage ascending flow rate in this tank is 0.2-0.3mm/S, the settling sludge will lifting to sludge storage tank by Solid air lift.

(3)Anoxia tank: the anoxia tank can use nitrate taken by the backflow mixed liquid and organism in influent water to make denitrification, to make the NO2-,NO3- convert into N2, to realize the denitrification purpose, reduce ammonia nitrogen when remove organism.

(4) Aerobic tank:

Sewage after treatment in anoxia tank, flow into contact oxygen tank, it is aerobic treatment , contact oxygen tank is biological treatment processing unit which mainly bio-membrane combine activated sludge , by supplying oxygen source, after pass by fully filled oxygen sewage, immerse total padding and flow pass padding in some speed, the padding grew bio-membrane fully contact with sewage, the organism in sewage will be adsorb ,degrade by micro-organism, to make the water quality purified.

(4) Second settling tank: the sewage after biochemical treatment will flow into second settling tank, ascending flow rate 0.1-0.15mm/s,surface loading less than 1.0m3/m2.h, discharge sludge using air lift to sludge storage tank.

(5) cleaning water tank: used to storage the treated water, the effluent water can be reused or discharge.

(6) Pump room: it set up above the sterilization tank, its inlet adopt two layer sound-proofing, the air intake has muffler ,fan filter, no noise when operation, air blower adopt two units L type roots blower , which can automatic replace operation, unit blower operation life about 30000h.
