Buried integrated sewage treatment equipment
First, the buried sewage treatment equipment applications:
Field of application suitable: for hotels, restaurants, nursing homes, hospitals, schools, shopping malls, residential quarters, villages and towns, port, railway stations, airports, military units, factories, mines, sewage treatment and other scenic areas.
Integration of buried sewage treatment equipment based on A / O biochemical process based, biodegradable sewage sedimentation, oxidation and disinfection processes in one sewage and industrial waste similar to domestic sewage, compact structure, small footprint, all set in the ground, running economy, impact concentration ability, high efficiency, easy management and maintenance by the user, the performance of the equipment are in line with the relevant requirements, the product has been recognized by the State Environmental Protection administration. These products will protect the human living environment to bring the gospel.
Second, the device characteristics
1, may be buried below the surface, the upper planting equipment, lawn, may be provided in the room.
2, no effect on the surrounding environment, the sludge produced less noise than the standard second-class areas.
3, automatic control, without professional management.
4, simple operation, easy maintenance, new technology, the effect is good, long life.
5, the device according to the standard layout, but also with the terrain requires special arrangements.
Third, the scope of equipment
1. Dealing with water: Standard for the 1.0 ~ 80.0 (m3 / h), is greater than 80.0 (m3 / h) required to be designed.
2, raw water concentration: BOD5: Standard ≤250mg / L, reinforced ≤400mg / L, Chaoguo 400 mg / L required to be designed.
3, the device is mainly applied to residential areas, hotels, docks, airports, shopping malls, nursing homes, schools, factories, mines and other industries sewage and similar industrial crap water.
Fourth, the sewage treatment equipment material selection
1, stainless steel structure
2, A3 steel structure
3, (Q235) steel, glass fiber reinforced plastic (FRP) composite structure
4, glass fiber reinforced plastic (FRP) Round
5, reinforced concrete structure
Fifth, the equipment process description
The design of the equipment mainly for industrial and domestic sewage and organic wastewater treatment. Its main processing means is the use of more mature biochemical treatment technology contact oxidation pond. Quality of design parameters by sewage influent BOD5 was 250mg / L, the effluent BOD5 of 20mg / L calculations. A total of seven parts: First ⑴ clarifiers; ⑵ anoxic tank; ⑶ contact oxidation pond; ⑷ secondary clarifier; ⑸ pool disinfection, disinfection means; ⑹ sludge tank; ⑺ fan room components.
⑴ sedimentation tank: the primary settling tank for the vertical flow sedimentation tank, sedimentation tank sewage upflow velocity of 0.3 to 0.4 mm / sec, sludge settling down to enhance the sludge tank. WSZ-5 and type the following equipment is not provided primary sedimentation tank.
⑵ anoxic: anoxic denitrification process is provided, the pool set YDT-type three-dimensional elastic filler, as a carrier of denitrifying bacteria, nitrification liquid ammonia and nitrate-back sub-acid oxygen under the action of denitrifying bacteria, reduced to nitrogen, the purpose to achieve nitrogen removal, anoxic tank effective residence time of 2.5 ~ 3.5h, dissolved oxygen control in ≤0.5mg / L.
⑶ contact oxidation pond: gravity sewage biochemical treatment pond to the contact, the contact is divided into three pools, a residence time of 8h, (enhanced equipment contact oxidation time up to 8 ~ 12h) elastic filler filler novel, easy conjunctiva, non-blocking contact oxidation tank gas-water ratio of 15: 1 or so.
⑷ secondary settling tank: biological wastewater flows after secondary settling tank, secondary sedimentation pool for vertical flow sedimentation, surface load of<1.0m3 / m2.h, mud up to the sludge tank.
⑸ pool disinfection, disinfection devices: disinfection tank according to specifications: "TJ14-74" standard of not less than 30 minutes, if the hospital sewage, pool disinfection residence time can be increased to 1 ~ 1.5h.
Disinfection using solid chlorine tablets dissolve in contact disinfection, disinfection of water the size of the device can not following the dosage change, to be more drugs and more water, less water and less dosing purposes, require additional disinfection means may be separately prepared according to the.
Sewage treatment equipment system for the automatic computer control, and fault alarm indicator.
wsz type equipment installation, use and maintenance
1, the device is placed in the form of two kinds: one floor above; Second, the floor or less.
2, requiring an average base pressure> 5t / m2, the foundation must be level. Equipment installed in the floor under the foundation and floor is relatively level with the device at the same height. Place equipment on-site sewage facilities in the passing of which is filled with water to prevent the groundwater floating equipment.
3, sewage treatment equipment must be checked before using the device's electrical system is normal, the fan motor oil meets the requirements until fully qualified.
4, sewage treatment equipment must establish a regular maintenance system, fans can not be reversed, regularly check the oil fan, fan air intake frequent cleaning. Fans, pumps each run 5000h maintenance time.
Buried apparatus main parameters:August 17, 2012, Feng total for the city television interview. On urban and rural integration to promote industrial restructuring across the development.
Note: The above parameters and equipment are for reference only, please refer to our actual parameters and the design sheet size prevail!
