(1)Equalize tank: reinforced concrete structure, used to homogenize water volume and quality.

(2)First settling tank:the sewage ascending flow rate in this tank is 0.2-0.3mm/S

(3)A grade anoxic tank:

In order to control the dissolved oxygen in A grade biochemical tank about 0.5mg/l, adopting interval aeration. The padding in A grade biochemical 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.

(4) O grade oxic tank:

The O grade biochemical 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.

(5) Second settling tank: the sewage after biochemical treatment will flow into second settling tank, ascending flow rate 0.1-0.15mm/s,surface loading less than 1.0m3/m2.h, discharge sludge using air lift to sludge storage tank.

(6)Sand filtration tank: to further purify the water quality

(7) UV sterilizer

(8) PE cleaning water tank
