Product description: (Qingdao) environmental engineering co., LTD. In the intermittent active sludge method (SBR) process is developed on the basis can make up for the deficiencies SBR sewage processing technology and equipment associated with; Can be widely used in various sewage treatment plant construction. Integrated equipment of sewage treatment principle is based on using activated sludge microbial organic knot method and biological membrane method and way of wastewater biochemical treatment. On the processing technology, a large number of microbial growth in fixed and floating biological carrier biofilm formation, with the impact of moisture in the wastewater of turning, bacteria and bacteria film of update, when the aeration using biological carrier, microbial with the pollutants in wastewater and improve the contact efficiency of oxygen. Overall processing equipment produced by the anaerobic anoxia aerobic three kinds of environmental effect in turn, increases the different kinds of sewage purification ability of microbial groups, strengthen the organic matter in sewage removal and the effect of nitrogen and phosphorus.

Scope: industrial and urban sewage treatment and other fields.

The main technical content

1. fundamental

Pool material made with high and new technology, make the sewage treatment equipment of whole set to advanced technology, reasonable configuration, excellent performance, good corrosion resistance, convenient maintenance, beautiful appearance. Pool material according to different reactor in the form of anticorrosive prefabricated steel plate, special sealing material leak proof, this kind of prefabricated steel plate form a protective layer can not only prevent the corrosion of tank, and has the function of strong acid, strong alkali resistance. Short build period; Corrosion resistance is strong; The sewage plant expansion to less investment and put into production soon

2. Technological process:

Regulating pool ­ - gas fugitive dust fall pool - YanYangChi - biological aerobic pool - the second pond - filter - water recycling pool

Process description:  

The design of the equipment is mainly for domestic sewage and industrial organic wastewater treatment. The main processing method is to use the relatively mature contact oxidation pool biochemical treatment technology. Water quality design parameters according to the sewage water is 250 mg/L BOD5, effluent BOD5 calculation for 20 mg/L. At the beginning of a total of seven parts: pond; Anaerobic pool; Contact oxidation pool; The second pond; Pool disinfection, disinfection device; The sludge pool; The wind of computer room.

(1) the early pond: early pond for vertical flow sedimentation tank, sewage in the rising velocity of settling basin is 0.3 ~ 0.4 mm/SEC, settle sludge to sludge pools. SFW - 5 pond, early and the following equipment is not set.

(2) anaerobic pool, anoxic pool Settings for nitrogen treatment, pool YDT stereo elastic filler is installed inside, as the carrier of denitrifying bacteria, nitrifying back into nitrate and ammonia and acid in liquid state under the action of denitrifying bacteria, oxygen reduction of nitrogen, achieve the goal of denitrification, anaerobic pool effective retention time was 2.5 ~ 3.5 h, dissolved oxygen control in 0.5 mg/L or less.

(3) the contact oxidation pool: complete wastewater biochemical treatment, to touch the touch the three levels, the residence time is 8 h, (enhanced equipment contact oxidation time up to 8 ~ 12 h) novel packing for elastic filler, conjunctiva, non-clogging, gas-water contact oxidation pool than about 15:1.

(4) the second pond: biochemical sewage flows into the second pond, the pond for the vertical sedimentation precipitation, surface load is < 1.0

3.Key technology 

The key to the high and new technology is:

1, the overall design the reasonable structure of the reactor tank;

2, prepare special anticorrosive coating process;
