Introduction:

With economic and population growth, increasing pollution of nature by human attention, the paper simply summarized the sewage treatment plant on the basis of operating experience, combined with my company's own scientific research and engineering practice to design a species can be buried complete set of organic wastewater treatment plant, the equipment used in the late nineties advanced technology and manufacturing techniques to produce glass steel, stainless steel as raw materials LHC series of sewage treatment equipment. The main purpose is to make life with similar sewage and industrial organic wastewater treated by the device to the user requirements of emission standards. The equipment is mainly used for residential quarters (including villas), luxury hotels, hospitals, office building and various public buildings sewage treatment, water treatment equipment by the water quality meet the national emission standards. Complete set of equipment can be buried in the ground, so also known as "buried sewage treatment equipment."
    The company buried sewage treatment equipment with international advanced biological treatment processes, set to remove BOD5, COD, NH3-N in one, with the technical performance, reliable, good effect, investment, small footprint, easy maintenance, etc. advantages. Our company also can be customized at the same time supporting water reuse facilities.
Second, product characteristics
1, buried in the ground below the equipment above the surface can be used as green or other sites, do not need housing and heating, insulation.
2, two biological contact oxidation process are used for plug-flow biological contact oxidation, the treatment is better than completely mixed or two series completely mixed biological contact oxidation. And small size compared with 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 easy to hang film, film, organic load in the same condition, and the organic removal rate was high, can increase the oxygen in the air solubility in water.
3, biochemical and biological contact oxidation pond with its relatively low filler volume loading, micro-organisms at this stage, their oxidation, producing less sludge, only three months (90 days) above a row of mud (or the use of night soil collection vehicle suction Sinotrans dehydration and cake).
4, the buried life of sewage treatment equipment, deodorizing way than conventional high-altitude exhaust, reprovision and soil deodorization steps.
5, the equipment handling system with automatic electric control systems and equipment failure alarm system, safe and reliable operation, usually by professionals generally do not need, just timely maintenance of equipment and maintenance. 
buried several sewage treatment plant to use 
Comprehensive system to deal with life, similar to the organic waste water and sewage; 
Glass steel, stainless steel, corrosion resistant, anti-aging properties such as excellent, the service life up to 50 years; 
Complete installation simple construction, easy operation, automatic control of all machinery and equipment are all devices can be set on the surface to; 
buried sewage treatment plant of the scope of
1, hotels, restaurants, nursing homes, hospitals;
2, residential district, village, town;
3, stations, airports, port terminals, ship;
4, factories, mines, military, tourist sites, scenic areas;
5, and domestic sewage of similar kinds of industrial organic wastewater.
