The cheapest PE biological septic tank is Shandong Xinda sewage treatment manufacturer. Features of PE biological purification tank:
The rural sewage purification tank system can be called a simple synchronous denitrification and phosphorus removal process. The total hydraulic retention time is shorter than other similar processes in anaerobic (anoxic) and good conditions. Under alternating oxygen operation conditions, filamentous bacteria cannot add a large amount of value and sludge expansion will not occur. The SVI value is generally less than 100, which is beneficial to the separation of mud and water after biological treatment.
No medication is required during operation. The two A sections only need to be gently stirred to avoid increasing the dissolved oxygen concentration, and the operating cost is low. Since the anaerobic, anoxic and aerobic zones are strictly separated, which is conducive to the reproduction and growth of different microbial flora, the nitrogen and phosphorus removal effect is better. A biological selection section is added to realize the selective requirements of biological activity.
PE Biological Johkasou Installation Requirements:
1. According to the rural sewage Johkasou installation diagram and foundation diagram, prepare the foundation based on the size of the installation plan, and prepare the concrete floor and foundation. The average pressure is required to be 5t/m2, and the foundation must be level.
It should be installed only after the concrete foundation pouring and maintenance period. If the equipment is installed below the floor, the relative elevation of the foundation from the floor shall be based on the dimensions shown in the drawing. At the same time, the surrounding excavation width and length must be away from the foundation. The edge is above 500mm to facilitate pipeline installation.
2. Pipeline installation and connection should be considered when the equipment is in place. When the equipment is in place, the self-weight of the equipment must be according to the instructions, and the tonnage of the crane must be matched. The installation sequence must be in place according to the on-site comparison diagram. The position of the cylinder, The orientation cannot be wrong and the spacing between each other must be correct. According to the installation diagram, connect the pipes. After the equipment is in place, tighten the connecting pipes with rubber pads to prevent leakage at the connections.
4. After the rural sewage purification tank is installed, the equipment and the basic floor must be connected and fixed to ensure that the equipment does not flow and float. At the same time, sewage must be injected into the equipment (when there is no sewage, use other water sources or tap water instead) , the fullness must reach more than 70% to prevent the device from floating.
5. After the rural sewage purification tank is installed without any problems, you can use soil to fill in the surroundings and gaps of the equipment, compact it, and level the ground. When filling the soil, please note that the equipment manhole cover must be higher than the floor. About 50mm. Do not allow soil to block the air inlet on the manhole cover.
6. Connect the control line of the electric control cabinet to the equipment. When wiring, pay attention to the direction of the underwater aerator and submersible sewage pump motor. For example, the basement control cabinet should be placed in a ventilated place and kept dry. Generally The control cabinet cannot be placed in the open air. Must be protected from the sun, rain, etc. This prevents the control board and terminals from leaking electricity and burning the control board.
