Price of buried medical wastewater treatment equipment——Application areas:

Including residential communities, rural towns, scenic spots, highway service areas, airports, docks, industrial and mining enterprises, and other wastewater.

The entire device is divided into the following processing units:
1The wastewater from the primary sedimentation tank is lifted by a lift pump to the regulating tankSWInside the device, the first step is to enter the primary sedimentation tank, which uses a sloping plate sedimentation tank. Under the action of gravity, the principle of shallow settling is utilized to settle most of the suspended solids and inorganic particles in the wastewater, while also removing some organic matter. In order to facilitate the extraction of a certain inclined plate at any time to clean the attached sludge that is difficult to slide off, the device uses a movable inclined plate. The bottom of the primary sedimentation tank is separated from the anoxic zone to avoid agitation of the mixed liquid in the anoxic tank, which affects the sedimentation effect of the primary sedimentation tank. The sludge in the primary sedimentation tank is regularly removed by a sewage truck.
2The anoxic tank is located in the interlayer between the biological turntable shell and the external box. In this space, the incoming water from the primary sedimentation tank is mixed with the return nitrification solution lifted by the hydraulic lifting rotor and the return sludge from the secondary sedimentation tank, and thoroughly mixed by a submersible mixer to complete the denitrification process. Nitrate nitrogen is treated by denitrifying bacteria Eventually, nitrogen gas is formed and escapes from the water, Ultimately achieving the goal of denitrification.
3The effluent from the anoxic tank in the interlayer of the rotating biological treatment unit after denitrification flows automatically to the rotating biological treatment unit. The rotating biological treatment unit is the core part of the device, which adopts a unique composite biochemical technology and can efficiently degrade pollutants under low energy consumption conditions. The entire rotating biological processing unit consists of three stages of bioreactors, each consisting of a biological rotor and a biological tank. The interior of each biological rotor is composed of multiple stages of biological impellers, each of which is equipped with a large number of spiral shaped biological blades.
Under the drive of the transmission device, three biological rotors rotate synchronously. Air (oxygen) enters through the air-water holes on the end face of the biological rotors and mixes with wastewater. Through the three-phase contact and mass transfer of oxygen, wastewater, and microorganisms, the degradation of carbonaceous organic matter and nitrification of nitrogen-containing organic matter are achieved. At the same time, the rotating biological leaves are washed away by wastewater, the aging biofilm falls off, and new biofilm forms, thus achieving the process of continuous renewal of the biological system. After nitrification, the wastewater is lifted by a hydraulic rotor to the middle distribution tank, which is controlled by a dam gate to control the flow of wastewater to the sedimentation tank and anoxic tank.

4The secondary sedimentation tank adopts an inclined plate sedimentation tank. Under the action of gravity, it uses the principle of shallow settling to precipitate a large amount of shedding and aging biofilm in the effluent of the rotating biological treatment unit. The clarified treated effluent enters the next unit. Part of the settled sludge enters the anoxic tank through the reflux sludge pump, while the other part is regularly transported out by fecal trucks as excess sludge.

The sedimentation tank mainly removes the aging biofilm and some colloids in the biochemical tank, further removing waterCODcr、BODEfficient sedimentation is a sewage treatment facility that integrates coagulation reaction, water distribution, water collection, and sludge discharge, with inclined pipe packing inside. Oblique pipe surface load:1.0—1.2m3/m2.hr

A sludge hopper and sludge pump are installed at the bottom of the sedimentation tank2Platform, used for transporting returned sludge and residual sludge. A sludge discharge device is installed at the bottom of the sludge tank, which regularly pumps the sludge from the sludge concentration tank for external treatment, and the supernatant is discharged to the regulating tank.

Price of buried medical wastewater treatment equipment——main features

WSZThe buried domestic sewage treatment device can be buried below the ground surface, which can be used as green or square land. Therefore, this equipment does not occupy the surface area, does not require building, and does not require heating and insulation.

WSZ-AOThe sewage treatment equipment is composed of steel structures and uses the latest domestic anti-corrosion coatings for corrosion prevention. Has acid and alkali resistance Salt gasoline kerosene is resistant to aging, abrasion, and rust. After applying this coating to the equipment, the anti-corrosion life can generally reach20Years or more.

WSZUnderground domestic sewage treatment plantAOThe biological treatment process adopts a push flow biological contact oxidation tank, which has a better treatment effect than a fully mixed or two-stage series fully mixed biological contact oxidation tank. And it has a smaller volume than activated sludge tanks, stronger applicability to water quality, good impact resistance, stable effluent water quality, and will not cause sludge expansion. At the same time, a new type of elastic three-dimensional material is used in the biological contact oxidation tank, which has a larger actual specific surface area, microbial biofilm formation, and convenient membrane removal. Under the same organic load conditions, it has a higher removal rate of organic matter than other fillers. Can increase the solubility of oxygen in water.

Due toAOIn the biological treatment process, a biological contact oxidation tank is used, which has a relatively low volume load of fillers and microorganisms are in the self oxidation stage, resulting in less sludge production. In addition, the moisture content of the sludge produced by the biological contact oxidation tank is much lower than that of the sludge produced by the activated sludge tank. Therefore, sewage is treated throughWSZThe amount of sludge generated by the series of sewage treatment equipment is relatively small, generally only requiring90Drain the mud once every day.

WSZIn addition to conventional measures such as vibration isolation pads and silencers, the buried domestic sewage treatment device also uses new sound-absorbing materials on the inner wall of the blower room to reduce the noise level during operation50Decibel reduces the impact on the surrounding environment.

WSZThe buried domestic sewage treatment device is equipped with soil deodorization measures, which utilize the upper space of the reinforced concrete structure pool to set up improved soil and air distribution pipes. When odorous components dissolve in the water contained in the soil through the soil layer, and then transfer into the soil due to surface adsorption and chemical reactions, Finally decomposed by microorganisms to achieve deodorization.

WSZThe buried domestic sewage treatment device is equipped with a fully automatic electrical control system and equipment damage alarm system. The equipment has good reliability, so there is generally no need for dedicated personnel to manage it, only monthly or quarterly maintenance and upkeep are required.

Price of buried medical wastewater treatment equipment——Foundation installation of buried water treatment equipment,use,maintenance
1,Basics:JHYSeries equipment placed above the floor,Just prepare a concrete floor with the same appearance as the equipment as the foundation. The basic pressure must be greater than4T/m2,At the same time, it also requires a certain level of proficiency,smooth.
If the equipment is buried below the floor,The basic elevation must be less than or equal to the equipment elevation and ensure that there is no water accumulation during rain,The foundation is generally plain concrete (whether reinforcement is required depends on the local geological conditions).
2,Installation: Position according to the installation diagram,Each box is positioned in sequence,Position of the box,The direction cannot be misplaced,The distance between each other must be accurate,And connect the pipeline properly.
