Price of rural domestic sewage treatment equipment in Sichuan

Price of rural domestic sewage treatment equipment in SichuanIt is a specialized equipment for treating domestic sewage in rural areas, aimed at solving the environmental pollution caused by the discharge of rural domestic sewage. These devices usually adopt an integrated design, integrating various processes such as physical treatment, biological treatment, chemical treatment, etc., and have the characteristics of small footprint, high processing efficiency, stable operation, and easy maintenance. The equipment is equipped with treatment units such as grilles, sedimentation tanks, biological reaction tanks, sedimentation tanks, disinfection tanks, etc. Through the synergistic effect of each unit, organic matter, suspended solids, nitrogen and phosphorus pollutants in sewage are effectively removed, ensuring that the effluent quality meets relevant discharge standards or reuse requirements.

Grille pool: responsible for intercepting floating miscellaneous goods in sewage, ensuring the normal operation of subsequent disposal equipment

● Conditioning tank: used to regulate water quality and quantity. The capacity of a regular conditioning tank is 6-10 times the hourly disposal capacity, and it is lifted to the anoxic tank by a lift pump.

● Anoxic tank: The anoxic tank is designed for denitrification treatment. The sewage separated by the grid is pumped into the anoxic tank by the sewage lift pump in the conditioning tank and mixed with the reflux nitrification liquid in the tank. NZP-II type packing is placed in the anoxic tank as a carrier for denitrifying bacteria to control nitrogen; Phosphorus; The removal effect of sulfides is good, with a residence time of 2 hours. It is separated from the sludge tank in the previous process to form an A/O treatment process, thereby achieving the purpose of phosphorus and nitrogen removal.

● Biological contact oxidation tank: It is divided into two stages with a total biochemical time of 6 hours. The first stage uses NZP-I type packing, which has excellent water flow characteristics. The second stage uses active carrier packing with Japanese technology, which is more conducive to microbial growth than external building blocks. The physical load of this packing reaches 30kg BOD/M3. d, which is more than 7 times that of ordinary soft packing. The biochemical tank adopts a central gallery microporous explosion, and the sewage circulates in the biochemical tank from time to time, fully contacting the organisms on the packing and achieving rapid degradation of organic matter.

Secondary sedimentation tank: The sewage after biochemical treatment enters the secondary sedimentation tank, which is designed to have an external load of 0.9-1.2M3/M2. h. The secondary sedimentation tank is an adjustable liquid level tank with a tooth shaped collection tank, which has a good horizontal water discharge effect. The sludge from the secondary sedimentation tank is lifted to the sludge tank.

Disinfection pool: manufactured according to national regulations TJ14-74, with a retention time of 30 minutes in the disinfection pool. The disinfectant used is solid chlorine pills or bleach powder, or aerospace sterilization stone. (Only QK-DM equipment has a disinfection tank).

● Sludge tank: The pollutants intercepted by the grid and the sludge from the secondary sedimentation tank enter the sludge tank, which is equipped with a sludge digestion system. The clear liquid on the sludge tank flows back to the conditioning tank.

The fan and distribution cabinet are both installed in the equipment room. In the ordinary equipment room, two fans are installed to alternate operation. When one fan malfunctions, the other can start the equipment on its own and continue to operate; When the sewage is cut off, the fan can automatically stop running to maintain the normal growth of organisms.
