Domestic sewage treatment equipment supplier in Hefei, Anhui, I believe that Wohua professional manufacturer
r .>/
r . type equipment is mainly designed for the treatment of domestic sewage and similar industrial organic sewage. Its main The treatment method adopts the currently relatively mature biochemical treatment technology < <> contact oxidation method. The water quality parameters are designed according to the general domestic water quality, inlet water < B<>/< <>, and outlet water < B<>/< <> indicators. There are a total of It consists of six parts: (< <>) Primary sedimentation tank (< <>) Contact oxidation tank (< <>) Secondary sedimentation tank (< <>) Disinfection tank and disinfection device: (< <>) Sludge tank (< <> ) Fan room, fan
r : > r . : r are discussed separately as follows
r . : r
r . : r < <>, primary sedimentation tank: equipment initial stage The sedimentation tank is a vertical flow sedimentation tank. The upward flow rate of sewage in the deep sedimentation tank is <..<> mm/second. The settled sludge is lifted to the sludge tank by air. (Note:
r . : /
r . : r .<>/< <>There is no primary sedimentation tank)
r . : r
r . : r < <>, contact oxidation tank: after initial sedimentation, the water flows to the contact tank for biochemical treatment. The contact tank is divided into [banned words], and the total residence time is < <> hours or more. The contact oxidation time of the enhanced equipment can reach < <> hours, and the filler is a novel filler, which is easy to form film and will not block. The specific surface area of the filler is < <>/< <>, and the air-water ratio of the contact tank is around < <>: < <>. (

r . : r < .<>/< <>, the contact pool is secondary)
r . : r
r . : r < <>, Secondary sedimentation tank: The biochemical sewage flows to the secondary sedimentation tank. The secondary sedimentation tank is two vertical flow sedimentation tanks, which operate in parallel. The upward flow velocity is < ..<> mm/second. The sludge is lifted to the sludge tank by air.
r : > r . : r < <>, disinfection pool and disinfection pool installation. The disinfection pool is according to the specification: < r<> The standard is < <> minutes. If it is hospital sewage, the residence time of the disinfection pool can be increased to < . <> hours, use the disinfection method of solid chlorine tablets contact and dissolution. The disinfection device can continuously change the amount of medicine added according to the amount of water output, so as to achieve the purpose of more water output and more medicine added, and less water output and less medicine added. Other disinfection devices can be prepared separately.

r . : r < <>, sludge tank: primary sedimentation All sludge from the pond and secondary sedimentation tank is lifted by air to the <> sludge tank for aerobic digestion. The clear liquid from the sludge tank returns to the heat exchange oxidation tank for reprocessing. There is very little residual sludge after digestion, and it is generally cleaned once a year. The cleaning method is to use a fecal suction truck to extend from the inspection hole of the sludge tank to the bottom of the sludge for suction and transportation. (

r . : /
r . : r The fan is located above the disinfection area. The entrance adopts double-layer sound insulation, and the air inlet has a muffler and a fan filter. , so there is no noise when running. The fan adopts two rotary fans, which can run automatically alternately. The operating life of a single fan is < <>about hours
