Remove parts of oil and grease
2.Screen channel
Main used to intercept big block floater in sewage, to guarantee follow-up processing structures normal operation and effective
reduce load, supply guarantee for system long term normal operation,
3. Equalize tank
Due to each time water quality.volume is different, the peak flow rate of average flow rate 2~8 times, thus sewage treatment
system steady operation, equalize water volume and homogenize water quality, build-in sewage pump and backflow measure, equip with aeration system to proceed pre-aeration, to guarantee certain rated flow rate lifting to integrated sewage treatment equipments and follow-up treatment steady, sewage lifting pump 2pcs .
4.Anoxic tank
In order to control the dissolved oxygen in oxic biochemical tank about 0.5mg/l, adopting interval aeration. the padding in
anoxic tank adopting new type elastic padding, height is 2.0m. such padding with the advantage of no easy blocking.light weight.
big specific surface area, treatment effect steady etc, easy to maintenance and change , retention time >>3.5hours.
5.Oxic tank(two grade)
In oxic tank equip with columnar biology carrier padding, this padding specific surface area is big, is 16-20 times comparing with
common biological padding, keep higher biomass, to reach the purpose of removing organic pollutant, aeration device adopting air blower and micropore aerator, the oxygen utilization rate is above 30, effective save operation cost. Retention time >>7 hours,
air water ratio about 12:1.
6.Secondary Settling tank
The sewage still contain large number of suspended solid after treated by oxic biochemical, in order to make the effluent water SS meet up discharge standard, adopting vertical settling tank to make solid liquid separation, the sludge will pump to sludge tank, at the same time, according to actual condition to make part of sludge backflow to anoxic tank to proceed sludge backflow,
increase the sludge concentration in oxic tank, improve removal efficiency.
7.Cleaning water tank
To storage cleaning water.
8.Sludge tank
The supernatant backflow to oxic tank to further treatment, few sludge after digestion. clearing manner can sucking and transport
out from sludge tank bottom using dung-cart.
9.Control room
Control room set in the air blower,uv sterilizer,filters,electric control carbinet
