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.

Features:

*This system with containerized package function: make the anoxia tank,MBR bio-reaction tank,sludge tank,cleaning water tank and operation room integrated into a big tank body, compact structure, process concise, small occupy area ( only traditional process 1/3-1/2) ,increment expansion convenient, high automatic degree, operating maintenance conciseness, it can move at anytime and anywhere, it can move to treatment goal location, direct large-scale to make proceed treatment, no need make twice construction.
*Gather sewage treatment and water purification process into one system, it shallow buried underground or ground; the treatment basic no sludge generate, hasn’t influence to surrounding; better operation effect,high reliability,effluent water quality steady,little operation cost.
* In treating municipal sewage, impact resistance,high remove efficiency to pollutant, strong nitration ability, it can make nitration,denitrification, both nitrogen and phosphorus removal function, suitable for treat municipal sewage,distributed sewage, the effluent can be reuse or can be discharge after reach standard, it can meet different users of different water quality.
* cleaning disinfection tank equip with packing which made of new type environmental protection active ion material, it has disinfection function and can effective remove the heavy metal ion in water, it can overcome medication washing disinfect caused secondary pollution and reduce the heavy metal content in effluent, greatly improve the recycle water quality.
* The aeration pipeline of membrane bio-reactor divide two parts, 1 part is make aeration to surrounding activated sludge , another part is make aeration to membrane module.

Its advantage is to make the membrane module mutual flap by aeration membrane module produce scour force, thus it can shake off the calcified sludge adsorb in the membrane fenestra surface, make the membrane flux greatly extend the membrane service life, thus reduce operation cost.

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.

Description of thesystemstep by step:

Sewage through the sewage pipe network to sewage treatment station, the first through the screen canal, skimming large particlesof suspended solids and impurities; and then into the sewage Equalization tank, homogenizing sewage, water regulation in the Equalization tank, the sewage from the sewage lift pump up to anoxic tank.

Sewage in the anoxic tank, denitrification process, to achieve further nitrogen removal.Anoxic tank effluent into the aeration tank, the treated effluent into the MBR reaction tank after the level of aerobic treatment.

MBR reaction tanks loaded hollow fiber membrane, microbial reaction vessel sewage biodegradability of pollutants in the assimilation and alienation.Most alienation productinto harmless CO2 and H2O, assimilate an integral substance of microorganisms. Film unit primarily to solid-liquid separation, the solid can be effectively microbes trapped in the reactor, to ensure the stability of water quality.

Sludge in the MBR tank part intosludge digestion tank, part back into the aeration tank.

Part of the aeration tank water back to the anoxic tank, providing nitrate and nitrite as anoxic, achieve the purpose of denitrification.
MBR reaction tank effluent directlyinto the clean water tank, after the water qualitystandard indicators, stay or return directly into the pipe network were Reuse.
Sludge collected sludge tank, and the supernatant back into the equalization tank.

Main treatment unit

(1) Front pretreatment tank:

In front of this device is anoxia tank, in one end of anoxia tank set water inlet, another side top set water weir tank and outlet water, can make the sewage stable nature flow into membrane reaction tank, equip floating packing and anoxia sludge, the sludge in anoxia tank HRT is 3-8h, give oxygen by interval, to make acidify,nitration and denitrification function, make the organism gradate translate into inorganics remove.

(2)MBR bio-reaction tank:

It has set water inlet in one side, and the immersed flat membrane module set in reaction tank, accommodate activated sludge, around aeration and membrane unit aeration pipeline connect with air blower, the matched collecting pipe in membrane module connect with suction pump, the untreated sewage enter into MBR biochemical reaction tank by water inlet, sewage HRT is 5h in reaction tank. After degrade by activated sludge in reaction tank, by resistance pollutant flat membrane module, then enter into cleaning water disinfection tank by suction pump. There set sludge lifting pump in aeration, it can lift the surplus sludge to sludge digestion tank interior; there has overflow in reaction tank top, it can make the sewage backflow into tank outside equalize tank; in below side open vent , in order to convenient for tank interior maintenance, cleaning.

(3) Sludge tank:

there are set sludge collecting hopper and sludge pipeline in sludge tank bottom, in order to convenient for sludge concentration, set weir water tank in top, there open mud discharge inlet in bottom, rely on static pressure automatic discharge mud.

(4)Cleaning water tank:

(5) Operation room:

It set 2 pcs air blower in operation room, operate 12h automatic shift 1 time, air blower equip with silencer damping measures; suction pump 2pcs, electric control cabinet 1pc, lighting system; in the top, equip with rain-proof air vent and ventilate convection device.

The above treatment unit integrated in a tank body, electric control cabinet automatic control each power plant operation.
