Small Integrated Sewage Treatment Equipment
Product Description
Product Description
Principle and technology of small integrated sewage treatment equipment-The whole device is divided into the following treatment units:
1. The wastewater from the primary sedimentation tank is lifted into the SW device through the lifting pump. The first sedimentation tank enters the primary sedimentation tank. The primary sedimentation tank adopts an inclined plate sedimentation tank. Most of the suspended solids and inorganic particulate matter settle down, and at the same time some organic matter can be entrained and removed. In order to facilitate the extraction of a certain inclined plate at any time to clean the attached sludge which is difficult to slide, the device adopts a movable inclined plate. The bottom of the primary sedimentation tank is separated from the anoxic zone to avoid the agitation of the anoxic tank mixture and affect the sedimentation effect of the primary sedimentation tank. The sludge in the primary sedimentation tank is regularly removed by a manure pump.
2. Anoxic tank The anoxic tank is located in the interlayer between the shell of the biological turntable and the outer box. In this space, the incoming water from the primary sedimentation tank, the return nitrification liquid lifted by the hydraulic lifting rotor and the return sewage of the secondary sedimentation tank The mud is mixed here and fully mixed by a submersible mixer to complete the denitrification process. Nitrate nitrogen will eventually form nitrogen under the action of denitrifying bacteria, which will escape from the water and finally achieve the purpose of denitrification. 3. Rotating biological treatment unit biological turntable The denitrified effluent from the sandwich anoxic pool flows to the rotating biological treatment unit by itself. The rotating biological treatment unit is the most important part of the device, and it adopts unique composite biochemical technology, which can degrade pollutants under low energy consumption conditions. The entire rotating biological treatment unit is composed of three-stage bioreactors. Each bioreactor is composed of a biological rotor and a biochemical tank. Each biological rotor is composed of multi-stage biological impellers, and each biological impeller is provided with a large number of spirals. Shaped biological leaves.
Driven by the transmission device, the three biological rotors rotate synchronously. Air (oxygen) enters through the air and water holes on the end of the biological rotor and mixes with wastewater. The three-phase contact and mass transfer of oxygen, wastewater, and microorganisms are used to achieve carbon-containing organic matter. Degradation and nitrification process of nitrogen-containing organic matter. At the same time, the rotating biological blades are washed away by the wastewater, the aging biological film falls off, and a new biological film is formed, thereby achieving the process of continuous regeneration of the biological system. The nitrified wastewater is lifted by the hydraulic rotor to the intermediate distribution tank, and the distribution tank is controlled by the weir gate to control the flow of wastewater to the sedimentation tank and the anoxic tank.
4. Secondary sedimentation tank The secondary sedimentation tank adopts an inclined plate sedimentation tank. Under the action of gravity, using the principle of shallow sedimentation, the effluent of the rotating biological treatment unit contains a large amount of fallen off and aging biofilms. The clarified treated effluent enters the next unit. Part of the sedimented sludge enters the anoxic tank through the return sludge pump, and the other part is used as the remaining sludge to be regularly transported out by the manure pumping truck.
