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.basic principle

 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 as < 1.0 m

3.Key technology 

The key to the high and new technology is:

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

2, the equipment of special anticorrosive coating process;

3, advanced processing technology. 
The main technical indicators and conditions

Technical indicators,

1, suitable for the situation of low investment, low cost and low energy consumption of air flotation - UASB hydrolysis - aerobic treatment process;

2, through the new technology, new materials and new construction technology will invest to a minimum.

3, through the use of advanced technology workers and advanced automatic control technology increase, decrease the cost of sewage treatment, the treatment cost in 0.3 yuan/m3.

The technical requirements

Strict and standardized operation and management.

Main equipment and operation management

1.The main equipment According to the requirement of the wastewater treatment process, to determine the specific requirement of equipment, general main equipment for the anaerobic USAB truss with aerobic SBR reactor. 

2.The operation and management This set of equipment operation is simple, easy to operate, as long as Ann normal operating procedures for operation and maintenance.

investment-benefit analysis

Economic benefit analysis

Adopt integrated wastewater treatment equipment technology, with considerable economic benefits, mainly displays in:

1, save raw material: is made of the steel plate welding and bolt connection each other to form the assembly. With the aid of computer aided design makes the overall design is reasonable.

2, improve the service life of equipment, through special craft processing, in the standard plate coated with glass fiber reinforced plastic coating inside and outside (or other forms of corrosion). Pretreatment of plate cylinder form a protective layer can not only prevent corrosion, and has the function of strong acid, strong alkali resistance. Life in more than 20 years.

3, low investment, because of less dosage of materials, fabricated structure installation is simple, less personnel requirements. This makes low investment. Its quality and much higher than the normal welded steel structure of the reactor, anticorrosion performance and service life can reach and exceed reactor made of stainless steel material, the price is only 1/2. Assembly of the reactor than the concrete unilateral cost can save more than 10%.

Environmental benefit analysis

Integrated wastewater treatment reactors used in organic wastewater treatment compared with the other bioreactor, has the advantages of low construction investment, short construction period, the characteristics of flexible installation, improve the overall treatment efficiency of the wastewater.

Electric control

Sewage treatment equipment for fully automatic computer control system, at the same time have the function of fault alarm indicator.

Equipment installation, use and maintenance:

Device is placed in the form of two kinds: one, above ground level ground, Second, the floor below. Requirements based on average pressure > 5 t/m2, foundation must be level. Equipment installed under the ground level ground, foundation and ground level ground of relative elevation and equipment of the same height. Site equipment in place is filled with water in the sewage equipment, qualified to prevent groundwater float the equipment. Sewage treatment equipment must be checked before using the equipment system of electric equipment is normal, the fan motor oil is in line with the requirements, until fully qualified. Sewage treatment equipment must be established a set of regular maintenance of system, fan cannot be reversed, regularly check the fan motor oil, fan inlet often clean up. Fan and water pump once every 5000 h operation maintenance.
