Description
Technical field
The utility model is related to sewage treatment field more particularly to sewage water denitrification process fields, are a kind ofly specifically
Buried AO techniques denitrification processing device.
Background technology
With development, the pressure of city water resource shortage is increasing, investigates the basic reason of Urban Water Crisis, people
It is becoming increasingly recognized that, is that society's cycle of water has exceeded the range that the Natural Circulation of water can carry.Therefore, water is only respected fully
Natural movement law, reasonably use water resource, make upstream area with water cycle do not influence downstream water domain function of water body,
The objective law that society's cycle does not damage Natural Circulation is only to maintain or restore the good water environment in city or even basin
The effective way of sustainable utilization of water resource.This requires us from the unidirectional style of opening of " water intaking-water delivery-user-discharge "
Water-use model be changed into the reaction type circulation process of " temperately water intaking-water delivery-user-recycled water ", improve the utilization of water
Efficiency.Realize the transformation of this great water-use model, it is crucial to reinforce reuse of wastewater.With the progress of science and technology, city
City's sewage has no longer been waste water, but a kind of resource of preciousness.Since being a kind of resource it is necessary to utilize to the greatest extent.It improves
The regeneration rate of municipal sewage, first, pollutant emission can be reduced, second is that having saved limited water resource.Big by Tsing-Hua University
It learns in " the 2010 urban water sector strategy forum " done with China Water host, expert points out, China's shortage of water resources, urban water shortage is asked
Topic protrudes, and waste water treating and reutilizing is strategic choice, significant.Municipal sewage treatment reuse subtracts while substituting cleaning water source
Lack quantity of wastewater effluent, reduced urban sewage load, has had the characteristics that water is stable, water delivery is apart from short, water producing cost is low, it can
It is the strategic choice for solving Urban Water Shortage Problem of Cities to provide safe and reliable replacement water source.Waste water treating and reutilizing work is promoted to fill
Divide and embody the people-oriented requirement of the Scientific Outlook on Development, reflects the eager desire of broad masses of the people, be that Promoting Urbanization is built
If desirability, be realize reasonable allocation of water resources, scientific conservation, the important means recycled, to Resources for construction saving
Type, friendly environment society are significant, significant to China's sound and rapid economic growth.
