Package Domestic Sewage Treatment Plant

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, produced the YMSZ 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, NH3in one, with the advantage of Technical performance stable and reliable, good treatment effect, save investment, small occupy area, and easy maintenance.

Feature:

1, can install ground level or underground ,above the plant 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, 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 threedimensional 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 Sinotrans).

4, the integration of deodorizing sewage treatment facilities in addition to the conventional way of high-altitude exhaust, comes 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,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.

Main treatment unit:

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

(2)Primary 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) Contact oxidation tank: 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.

(4) Second settling tank: 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.

(5) Disinfection tank:

(6) Sludge storage tank: all sludge in the primary settling tank and second settling tank 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 12 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.

(7) Air blower 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.

Technology process:

The effluent water from septic tank will first flow into grilling well , the grilling can remove bigger suspended matter, seston and ribbon in sewage, then flow into equalize tank, the equalize tank function is equalize sewage volume and quality, make the sewage enter into the

integrated sewage treatment equipment by lifting pump.

The sewage first enter to the primary settling tank of integrated sewage treatment , In the primary settling tank , due to organic matter content is high, Microbes in anaerobic condition, at this time, microbes is facultative microbes, they make the organic nitrogen into ammonia nitrogen in sewage ,

Use of organic carbon source as electron donor, make convert into N2 ,and adopt parts of organic carbon source and ammonia nitrogen synthesis new cells material. So the primary settling tank has the function of organic matter removal, reduce organic loading of subsequent three level biochemical tank, good for proceeding nitrification ,

and rely on high content organic matter in sewage ,finish denitrification, final eliminate nitrogen eutrophication pollution. after pass by primary settling tank biochemical action,

the sewage still contain some organic matter and higher content ammonia nitrogen. in order to make the organic matter further oxygenolysis, at the same time, carbonation tend to be completely, nitrification can proceeding smoothly, so set contact oxidation 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 primary settling tank and contact oxidation tank all install padding,

the whole Biochemical process rely on many microbes attached on the padding. The dissolved oxygen in primary settling tank is control around 0.5mg/L, but in contact oxidation tank the dissolved oxygen is above 2mg/L,some effluent water from contact oxidation tank back flow into equalize tank proceeding internal Circulation,

so achieve denitrification purpose, another parts will flow into secondary settling tank, proceeding solidliquid separation, the effluent water after separated will enter into disinfecting tank, the effluent water after disinfection treatment by chemical agentia will reach to standard and reuse in irrigation.
