2. Adjustment pool: used to regulate the water quality and quantity, the general volume of the adjustment pool is 6-10 times the hourly treatment capacity, with lifting pumps to the anoxic pool.
3. Anoxic tank: anoxic tank for denitrification treatment and set up, after separation of sewage grating through the sewage lifting pumps in the regulating tank pumped into the anoxic tank and the pool of reflux nitrification liquid mixing, anoxic tank placed in the NZP-II-type filler as a denitrifying bacteria carriers, nitrogen; phosphorus; sulphide removal effect is good, the retention time of 2 hours with the continuation of the process of sludge pools combined with the formation of the A/O method treatment process, so as to achieve the purpose of dephosphorization and denitrogenation.
4. Biological contact oxidation tank: *** divided into two levels, the total biochemical time of 6 hours, before the first level of NZP-I-type filler, the filler water flow characteristics are very superior, the second level of flow carrier filler (Japanese technology), the filler than the surface area of wood, conducive to the growth of microbial treatment load up to 30kgBOD / m3 ?d is the general soft filler 7 times more than the biochemical tank using The center of the corridor microporous air explosion, sewage in the biochemical tank continuously circulating, fully in contact with the biological phase of the filler to achieve rapid degradation of organic matter.
5. Two sinks: after the biochemical sewage into the two sinks, two sinks designed surface load 0.9-1.2m3/m2?h two sinks for the lifting adjustable level, tooth-shaped water collection tank, the tank collection of water uniformity of the water effect is better, the two pools of sludge gas lift to the sludge tank.
6. Disinfection pool: according to national standards: TJ14-74 production, disinfection pool residence time of 30 minutes, the disinfectant using solid chlorine pills or bleach, or the U.S. bactericidal stone. (Only BZHC-C type equipment has a disinfection tank)
7. Sludge tank: the dirt intercepted by the grid and the second sedimentation tank sludge into the sludge tank, sludge tank with a sludge digestion system, sludge tank supernatant reflux to the regulating tank.
8. fans and distribution cabinets are set up in the equipment room, Rundle purification experts introduced the general equipment room is equipped with two fans running alternately, when a fan failure, the other can start their own equipment can be run continuously; when the sewage breaks down, the wind machine can automatically rest run to protect the normal growth of organisms.
