Description
Technical field
The invention belongs to the technical field of sewage in environmental project, and in particular to a kind of unpowered high load capacity underground infiltration
Filter sewage treatment composite system and method.
Background technique
In recent years, the attention of protection of the water environment and investment are continued to increase with national and local governments, water environment
Prevention and treatment achieves certain effect, and still, water pollution serious situation in China's does not obtain essence containment yet.For example, China it is industrial,
Agricultural and domestic pollution discharge load are big, and National Chemical oxygen demand total emission volumn is 2294.6 ten thousand tons, and ammonia nitrogen total emission volumn is
238.5 ten thousand tons, remote hyperenvironment capacity；In national earth's surface land that abounds in rivers and lakes control section, still there is 9.2% forfeiture water body (to be inferior to V using function
Class), 24.6% emphasis lake (reservoir) is in eutrophic state；The river irrigation canals and ditches for much flowing through cities and towns are black smelly etc..
For the severe situation of China's water pollution, State Council is formal in 2015 to have issued " water prevention and cure of pollution action meter
It draws ".This document highlights the importance of science and technology support, encourages to accelerate research and development foresight technology, including sanitary sewage low cost
High standard processing technique.Therefore, the good sanitary sewage disposal technology of research and development low cost, environmental benefit is the Strategic Demand in China,
Have great importance to the water environment pollution control in China.
Waste water soil treatment system reduce processing cost on have unique advantage, mainly include sewage slow rate,
Quickly diafiltration, overland flow and underground are percolated five seed types.Wherein, subsurface wastewater infiltration system does not give an offensive smell, no because being embedded in underground
Landscape is influenced, is widely used in European and American developed countries.But traditional subsurface wastewater infiltration system takes up a large area, and is difficult to push away in China
Wide application.The patent of invention that Authorization Notice No. is CN103641270A and CN102432105B is mentioned by intermittent pump, power is logical
The sewage load and effluent quality of subsurface wastewater infiltration system, Er Qieyu is greatly improved in the multiple means such as wind and structure optimization
Traditional biological technology is compared, and energy consumption is very low, and management service is easy, therefore is suitable for the place of the sanitary sewages such as village, town, holiday resort
Reason.But when (or when handling several tons of sanitary sewages day) sanitary sewage for handling a family, a few family residents, due to needing to purchase
The equipment such as submersible sewage pump, Middle pressure draught fan, control system are set, cause ton water investment too high, therefore and be not suitable for.In addition, in mountain area etc.
Topography has the place of drop, power supply instability, and unpowered technology is obviously more favourable.
Since system for anaerobic treatment is without being aerated oxygen supply, it is highly convenient for being designed to unpowered sewage disposal device, therefore, very
It is multiple it is bright in this way, such as notification number be CN101613169B patent of invention.However, due to organic matter, ammonia nitrogen
Removal is required to consumption oxygen, therefore the effluent quality of anaerobism unpowered sewage disposal device is poor, is unable to qualified discharge.
The oxygen delivery capacity of unpowered sewage disposal device is the key that decision systems success or failure.If traditionally lower diafiltration is not adopted
It is exactly unpowered device, but due to oxygen limitation, load-bearing capacity is very low (generally less than 5cm/d) with pump hoisting way water distribution.
Compared with continuous water distribution, intermittent water distribution helps to build the environment of alternation of wetting and drying inside underground is percolated and improves its reoxygenation energy
Power, to improve system to the removal effect of aerobic pollution.The developed countries such as America and Europe use siphon side in subsurface wastewater infiltration system
The intermittent water distribution of formula reduces system energy consumption and failure rate, but sewage load is not significantly improved.
Siphon water distribution also has application in artificial swamp.The utility model patent that Authorization Notice No. is CN201272717Y is logical
Setting inverted U and L-type siphon pipe are crossed, the intermittent unpowered water distribution of vertical current constructed wetland is realized.With traditionally lower diafiltration
System is similar, only leans on intermittent water distribution, reoxygenation ability is limited, still cannot increase substantially sewage load.Authorization Notice No. is
The patent of invention of CN101671092B has been invented a kind of combined tidal flow artificial wetland sewage disposal system, has been realized by siphon
Intermittent loading and draining, the oxygen intake in filtrate evacuation procedure increase the reoxygenation ability of system.But it is negative in height
Under the conditions of lotus, such offering oxygen way still may be insufficient, in addition, bottom denitrification zone may lead to denitrification because lacking organic carbon source
Effect is poor.
