First, an overview
With economic and population growth, pollution of nature become more and more human attention, summarized and sewage treatment plant based on operating experience, combined with my own scientific research and engineering practice to design a buried set complete set of organic wastewater treatment plants, their equipment late at home and abroad in the 1990s advanced technology and manufacturing technology to produce as the main raw material of glass, steel, stainless steel ZWF series of sewage treatment equipment. Its main purpose is to enable the user requirements of emission standards for sewage and similar industrial organic wastewater treated by the device. The equipment is mainly used for residential quarters (including villas), luxury hotels, hospitals, office buildings and various types of public buildings, sewage treatment, water quality processing by the device, the national emission standards. The full set of equipment can be buried in the ground, it is also known as "buried sewage treatment equipment.
This company adopts the international advanced biological treatment processes buried integrated sewage treatment equipment, set removal of BOD5, COD, NH3-N in a, with a stable and reliable technical performance, better handling, investment, small footprint, easy to maintain and so on. I also can according to customer requirements while supporting water reuse equipment.
Second, product characteristics
■ 1, buried below the surface, the surface of the device above can be used as green or other land, no housing and heating, thermal insulation.
■ 2, two biological contact oxidation process using a plug-flow bio-contact oxidation, its better than dealing with a completely mixed or two series of completely mixed biological contact oxidation tank. Than the small size of the activated sludge, water quality, adaptability, resistance to shock loading performance, water quality and stability will not result in sludge bulking. Pool, new flexible three-dimensional packing, a large surface area, microbial easy to hang the film, stripping, the same organic loading conditions, can improve the solubility of oxygen in the air in the water, the organic removal efficiency.
■ 3, biochemical pool with biological contact oxidation method, FORM. The relatively low volume loading of filler, the microorganisms in their oxidation this stage, less sludge production, only three months (90 days), more than row once mud (truck pumping or dehydration as cake Sinotrans).
■ 4, buried sewage treatment equipment, deodorant in addition to conventional high-altitude exhaust, comes with a soil deodorization measures.
■ 5, the entire device processing system with a fully automatic electrical control systems and equipment failure alarm system safe and reliable operation, usually does not require special management in a timely manner, just the equipment maintenance and repair.
Third, the use of
■ be able to handle living systems integrated wastewater and similar organic wastewater;
■ glass, steel, stainless steel structure, has excellent corrosion resistance, aging characteristics, and service life of more than 50 years;
■ the construction of a full set of device is simple and easy to operate all machinery and equipment are automatic control, all devices can be set below the surface.
Fourth, the scope of
■ 1, hotels, restaurants, nursing homes, hospitals;
■ residential district, village, town;
■ 3, stations, airports, port terminals, ship;
■ 4, factories, mines, military units, tourist spots, scenic areas;
■ 5, similar to the sewage of a variety of industrial organic wastewater.

■ 1, Foundation: ZWF device placed on the floor above, just to prepare an equipment shape concrete floor as a basis. The basis of pressure must be greater than 4T/m2 also require the level of formation. Equipment buried in the floor below the foundation level must be less than or equal to the equipment elevation and to guarantee the rains not water, is generally based on the plain concrete (reinforcement depending on local geological conditions).
■ 2 installation: place according to installation diagram, each box in turn place the location of the box, the direction can not misplaced, mutual spacing must be accurate, and piped. Water in the device, check the pipe for leaks, if not then the box around the casing, until the equipment inspection holes, and flat ground. Control line and the pump of the electrical control box connected to the electronic control box connected to the mains wiring, pay attention to fans, motors turn, must be referred to with the fan in the same direction.
◎ underground type sewage treatment plant construction
■ equipment, all piping using PVC pipe or stainless steel tube, pipe connection with PVC adhesive bond or stainless steel welding.
■ filler suspended biological filter media for biological carrier, biological capacity, easy to hang the film, no cabbage, no blocking.
