Mud and dirt in air substance can directly be mixed into flowers in scale removal process and be used as fertilizer with greening.Most terminal outlet,
The water body for leaving the system reaches in line standard, need not again be handled into municipal sewage pipe network.The technique
Suitable for food processing factory, the enterprise of degradable Chinese medicine or the processing of other natural animal-plants.Waste water has toxic
Factory or heavy metal enterprise are not suitable for this technique, when on-site has largely recycled water more than needed, can lead to water body nearby and occupy
It is used in the square of people accumulation regions or market landscape water body, aeration least significant end reaches discharge standard.But need reinforced pipe
Reason adds warning sign, illustrates not allow to be in direct contact water body.
The main energy consumption of this system is analyzed as follows in the comparative analysis of the part of water power according to practical engineering experience：
1,1 yuan of electricity Unit Price often spends calculation, and there are three 0.75 kilowatt of motors in whole service system.Industrial water unit price is
3.5 yuan per ton.
2, it is calculated with 80 tpds of waste water total amount, the electricity charge are 18 yuan daily, 8 tpds of toilet cycle saving water, factory
Water-saving about 1 tpd of area's green area irrigation, water-saving 31.5 yuan altogether.The utilization rate that this system can generate regeneration water is 100%,
Facilitate periphery to use, therefore may be implemented to get a profit.
3, when the amount through excessive reclaimed wastewater reuse increases, enterprise has an opportunity completely in the case of profit may be implemented, operation
Sewage treatment facility.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., be all included in the scope of protection of the present invention.
