Overview
With the growth of economy and population, the pollution of nature has attracted more and more attention from mankind. On the basis of summarizing the introduction of foreign domestic sewage treatment equipment, combined with its own scientific research results and engineering practice, a complete set of organic sewage treatment equipment that can be installed underground is designed. The equipment adopts the technology and manufacturing technology introduced in the 1990s to produce glass fiber reinforced plastics as the main raw material.WSZ-FSeries sewage treatment equipment. Its purpose is mainly to make domestic sewage and similar industrial organic wastewater meet the discharge standards required by users after being treated by this equipment.
How to use
1, the equipment is generally installed underground, and the upper part of the equipment can be used as a green belt, parking lot, road, etc.
2, the equipment can also be placed in a semi-buried type, and the depth of the buried type can be determined according to your needs.
3, the equipment can also be placed above the outdoor surface.
4. If the equipment is used in cold areas, the inspection hole can be heightened so that the equipment can be buried below the frozen soil layer.
5, This equipment can not be arranged according to the standard layout, but can be arranged according to the needs of the terrain.
Features
1, capable of treating comprehensive wastewater from living systems and similar organic wastewater.
2, adopts fiberglass structure, has excellent characteristics such as light weight, corrosion resistance, anti-aging, etc., and has a long service life.50Years and years.superior.
3, The complete set of equipment is simple to construct and easy to operate. All mechanical equipment is automatically controlled, and all equipment is set below the surface.
4, Management and maintenance are convenient, and the equipment is equipped with a microcomputer fully automatic control system.
5, Perfect equipment tracking and after-sales service.

WSZ-F(A,B,C)Device Description
According to the different requirements of users, local environmental protection bureaus and design institutes, WSZ -FTypes of sewage treatment equipment are discussed as follows:
WSZ-FAType is used for sewage treatment without disinfection requirements.
WSZ-FBType is used for sewage treatment with disinfection requirements.
WSZ-FC type is used for sewage treatment with denitrification, dephosphorization and disinfection requirements.
Walking around
Note: When the equipment is buried in a green belt and only pedestrians are required on the upper part, the uniform load on the equipment foundation is4t/m²Above, the equipment and foundation are connected with anti-floating straps to prevent groundwater from floating the equipment.
Take the model
Note: When the equipment is buried under a road or parking lot, the load on the upper part of the equipment is transferred from the reinforced concrete cover plate back to the columns, and the columns are transferred back to the bottom plate, and the equipment does not bear the load.
Process description
WSZ-FType sewage treatment equipment is mainly used for the treatment of domestic sewage and similar industrial organic wastewater. Its main treatment method is to use currently relatively mature biochemical treatment technology.-Biological contact oxidation method, water quality design parameters are calculated according to general domestic sewage water quality design, according toBOD5average200mg/l, out of waterBOD5according to20mg/ldesign.
WSZ-FThe equipment mainly consists of seven parts
Two grilles are used, one for backup and one for use.
2. Anoxic tank: Anoxic tank is set up for denitrification treatment. The sewage after grid separation flows into the anoxic tank and is mixed with the reflux nitrification liquid in the contact tank. NZP-II type filler is placed in the anoxic tank as a carrier of denitrifying bacteria. The filler has good removal effect on nitrogen, phosphorus and sulfide, and the residence time is 2Hours. They are combined with the sludge tank in the previous process to formA/Otreatment process, thereby achieving the purpose of dephosphorization and denitrification. (onlyWSZ-FCtype equipment has a disinfection pool)
3. Biological contact oxidation tank: divided into three levels, with a total biochemical time of 6 hours, the first two levels adopt NZP-Ⅰtype filler, which has good water flow characteristics and is used in the third stage NZP-Ⅱtype packing, which has a large specific surface area and a processing load of up to14kgBOD/m³.dIt’s a general filler5-10times, the biochemical tank adopts micropore aeration in the central corridor, and the sewage is continuously circulated in the biochemical tank, fully contacting the biofilm on the filler, and achieving rapid degradation of organic matter.
4. Secondary settling tank: The biochemical sewage enters the secondary settling tank. The designed surface load of the secondary settling tank is 0.9-1.2m³/m².dThe secondary sinking tank is a lift-type adjustable liquid level, toothed collecting tank, which has better uniform water collection and sedimentation effect, and the secondary settling sludge is lifted to the sludge tank.
5. Disinfection pool: according to national standard: TJ14-74Production, the residence time of the disinfection pool is30Minutes, the disinfectant uses solid chlorine pills or bleaching powder, usually added once a week.
7. Fan room, automatic control cabinet: The fan room is set up separately, Equipped with two imported fans, the fan room and microcomputer control cabinet are integrated, The air outlet duct of the fan room and the equipment air inlet duct are connected, and their distance does not exceed15rice. Settings before sewage enters the equipment - regulating pool to adjust the quality and quantity of sewage. The effective residence time of the regulating pool is generally 4-8 Hours. A grid cage is installed at the entrance of the regulating pool to intercept large particles of debris in the sewage and ensure the normal operation of the water pump.
