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, can set on the ground or underground, if underground, above the surface can be used as green or other land, no housing and heating, insulation.
2, two biological contact oxidation process are the use of plug-flow bio-contact oxidation, this 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).
4, the integration of deodorizing sewage treatment facilities in addition to the conventional way of high-altitude exhaust, coming with a soil deodorization measures.
5, the entire processing system is equipped with 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.

3. Stations, airports, port terminals and ship.

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

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

Main equipments:

 

 

(1)Grilling well: remove branch,plastic etc Larger impurities.

(2)Regulating tank: homogenize water volume and quality.

(3)Primary settling pond: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.

(4) Contact oxidation pond: the primary settling sewage will flow into here proceeding biochemical treatment, it can divide three-level, the total retention time is 4-6h, padding is novelty elastic padding, easy to membrane, no blocking, padding/surface area is 160m2/m3, gas-water ratio is about 12:1.

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

(6) Disinfection pool

(7) Sludge storage pond: all sludge in the primary settling pond and second settling pond need air lifting to sludge storage pond, then proceeding aerobic digestion, the supernatant liquor in sludge storage tank backflow into contact oxidation pond reprocessing , the surplus sludge is very little, it need clean 1 time every 1-2 years usually, cleaning manner can be use fecing suction truck stretch into sludge tank bottom from manhole of sludge storage tank sucking it and transport outward.

(8) Fan 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.
