Description
Technical field:
The invention belongs to sewage treatment area, particularly to a kind of ecological garden formula sewage water treatment method and be
System.
Background technology:
Owing to large amount of sewage treatment plant of China built up in " 95 ", Tenth Five-Year Plan Period, discharge mark
Alignment request is relatively low, and urban wastewater treatment firm carries mark and transforms: State Environmental Protection Administration's environment-development
In [2005] No. 110 " about the notices of strict implement " urban wastewater treatment firm pollutant emission standard " "
" for preventing waters from eutrophication occurring, the water outlet of town domestic sewage treatment plant enters country in proposition for the first time
With save the major river valley that determines and lake, reservoir etc. are closed, semiclosed waters time, " standard " should be performed
The A standard of middle primary standard ".No. 21 bulletin in 2006 proposition has reiterated this problem, and this is real
In regulation aspect, the scope of application of GB18918-2002 primary standard A standard is directly expanded to absolutely on border
Most of urban wastewater treatment firms, urban wastewater treatment firm one-level A proposes mark transformation in many basins and provinces and cities
A large amount of enforcements.
Traditional waste water treatment process has a following drawback: 1) traditional wastewater treatment plant is because sewage treatment facility
In profile the most unsightly, abnormal smells from the patient is big, is generally positioned in the large-scale production capacity concentrated water outside city scope
Mud groups of building；2) the universal nitrogen of water outlet, phosphorus concentration are processed the most up to standard；Along with the change of people's living habit,
Traditional handicraft is difficult to remove refractory organic compounds in water so that water outlet is difficult to meet one-level emission standard A；
3) concentrated treatment facility is again such that dirty water reuse becomes an intensive capital business, needs
Building a large amount of auxiliary equipment (piping network) from reality with producing, incity resident and commerce area will
Sewage causes treatment plant；4) operation cost is higher；The big process of mud generation amount is relatively costly.
In country and the area of great attention sustainable development of some water resources shortages, find alternative
Property sewage disposal scheme is the matter of great urgency already.
The information being disclosed in this background section is merely intended to increase the reason of the general background to the present invention
Solve, and be not construed as recognizing or imply in any form that this information structure is for this area general technology
