Zhejiang buried domestic sewage equipment, Zhejiang sewage reuse equipment, Zhejiang chemical industry sewage equipment
Application scopes of buried domestic waste water equipment:
Residential communities, restaurants, hotels, sanatoriums, schools, mines, factories etc. domestic waste water treatment equipment and other similar industrial waste water treatment, there are more than 30 kinds specifications, such as the capacity is 0.5~, depth of ground 50m3/h.
I. Technology instructions
The design of buried domestic waste water equipment is aiming at the treatment of domestic waste water and similar industrial organic waste water. The main treatment methods is to adopt the mature biochemical treatment technology— contact oxidation method, the general water quality parameters are that the feedwater is bod20mg/l, effluent is bod20mg/l, there are six parts: (1). Primary sedimentation tank; (2) contact oxidation pool; (3) secondary sedimentation tank; (4) disinfection pool, disinfection device; (5) sludge pool; (6) fan roon, fan;
there are the following descriptions:
Primary sedimentation tank: the primary sedimentation tank is the vertical flow sedimentation tank, the rising rate of waste water on the sedimentation tank is 0.6-0.7mm/s, the settled sludge is risen by air to sludge pool.(notes: no primary sedimentation tank for 0.5-5m3/h)
Contact oxidation pool: water after primary sedimentation will flow to the contact oxidation pool to have a biochemical treatment, contact oxidation poll has been divided into three grades, the total retention time is more than one hour. Contact oxidation time of strengthen equipment is about 6 hours, the filling material is the new trapeziform filling material, which is easy to have a conjunctiva, difficult to block. The gas is contrast to water in the contact oxidation pool is about 12:1.(notes: contact oxidation poll is the second grade.)
Secondary sedimentation tank: the waste water after biochemistry will flow to secondary sedimentation tank, secondary sedimentation is the double vertical flow sedimentation tanks , which are operating in parallel. The risen flow is 0.3-0.4mm/s. Sludge discharge will be risen by air to sludge pool.(notes: 5-5mt/h, sludge will flow to the sludge pool automatically.)
Disinfection pool and disinfection device: “tji4---74”standard is 30min, if the hospital sewage, disinfection pool can add the retention time to 1-1.5 hour, take use of solid chlorine contact dissolving to disinfect, the disinfection device will change the adding drug quantity based on the output, if there is more effluent, there will be more drugs, if there is less effluent, there will be less drugs. Other disinfected devices can be prepared separately.(notes: no need of disinfection pool and disinfection device for industry sewage)
Sludge tank:all the sludge of primary sedimentation tank and secondary sedimentation tank will be risen by air to the sludge tank to have the aerobic digestio
