First, the main technical content
(1) the basic principles of
Smart water reuse equipment is a set of sewage treatment and water reuse as one of the intelligent processing unit, the combination of activated sludge and membrane separation technology, and to the membrane instead of the traditional biological wastewater treatment process in two sedimentation tanks, the efficient retention of the membrane under the mud completely separated. Due to the diversion effect of the membrane to maintain the system's high concentration of activated sludge, is conducive to growth and reproduction of nitrifying bacteria, biochemical reactions and the denitrification rate, reducing the excess sludge production to solve the traditional biological treatment processes prevalent instability of the water quality, large area, operation and maintenance of complex, prone to sludge bulking causes the deterioration of water quality, and outstanding problems.
(2) key technology
A. Use of integrated design, equipment and technology is highly integrated, small footprint system;
Two. PLC automatic control system;
3. Composite aeration;
4. Built-in chemical membrane cleaning method.
(3) typical scale
The gold medal water daily treated water classification, the total processing capacity of 30m3 / d, 50m3 / d, 100m3 / d, 200m3 / d, 300m3 / d, 400m3 / d of the series model.
Second, the main technical indicators
Water quality and stability after the device processing to achieve and better than the national urban wastewater recycling for urban miscellaneous water quality "GB/T18920-2002 standard, the specific water quality objectives in Table 1:
Table 1 and out of the water quality indicators

Major equipment and operation management
(1) major equipment
Integrated intelligent water reuse equipment, as well as fans and other ancillary equipment.
4, operation and management
All PLC automatic control, so that the whole system has simple operation run management, management of professional and technical and not ask for much, etc., easily in a variety of conditions to achieve better management of the entire processing system to ensure the normal operation of the system.
Fifth, the scope of
Schools, residential areas, tourist scenic spots, the new rural construction, highway service areas, enterprises (organic industrial waste water), docks, hotels, airports, railway stations, business services areas, golf courses, small enterprises and units distributed sewage, organic industrial wastewater treatment and reuse.
Six, investment benefit analysis
(1) investment
A. Tons of water investment: 3000 ~ 3500 yuan;
Two. Tons of water covers an area of: 0.15 ~ 0.20m2;
3. Tons of water consumption: 0.25 to 0.6 degrees;
4. Tons of water supplies: 0.20 to 0.25 yuan;
5 Tons of water running costs: 0.50 ~ 0.70 yuan.
Analysis of economic benefits
Reuse of water can save the water fee, and have good economic benefits.
Higher north of the price of water, Beijing, for example, to calculate a processing capacity of 100m3 / d of complete sets of equipment, the device can be realized annual water consumption 3.65 million tons, saving water of 179,000 yuan, the annual run The cost is only 25 600, can be achieved an annual economic benefit of 153,400 yuan, equipment investment recovery period is 19 months.
Environmental benefits.
Water reuse wastewater will reduce emissions, reduce pollution of the city receiving water body, opened up a second water source for urban wastewater reuse, reduce the dosage of urban fresh water to take to alleviate the shortage of urban water supply pressure and burden, sustainable development of cities to bring great environmental benefits.
