Description
Technical field
The invention belongs to environmental monitoring technology field more particularly to it is a kind of simulation rural area septic tank draining experimental provision and
Its application method.
Background technology
The Taihu Lake basin area one of the most flourishing as regional economy, in recent years, it is fast that rural people occupies living standard
Speed improves, life style increasingly urbanization, and the discharge of a large amount of untreated sanitary sewages causes rural environmental pollution horizontal
Greatly improve, rural scattered domestic sewage has become the important sources of Taihu Lake basin nitrogen and phosphorus pollution, as a result, Taihu Lake basin by
Step has carried out domestic sewage in rural areas improvement and treatment facility construction, with biochemistry --- and eco-treatment technology is main stream process technique,
Common technology include artificial ecology wetland, capillary infiltration trench, tower earthworm ecological filter tank, buried microkinetic oxidation ditch and
Integrated biochemical treatment reactor based on SBR, MBR etc. etc., currently, conventional process treating capacity accounts for the existing life dirt in rural area
80% or more of water process total amount.However, effective operation of rural domestic sewage treatment facility is a long-term engineering, due to fortune
The problems such as row expense and treatment facility are safeguarded cause existing a large amount for the treatment of facilities can not normal operation, it is happy equal that Taihu Lake is flowed
It is found after the operating condition investigation of 210, domain rural domestic sewage treatment demonstration project, about 8% never runs, remaining engineering
Once there is the phenomenon that being unable to operate normally.Therefore, in the input for establishing rural domestic sewage treatment very well equipped
And before administrative mechanism, adaptation to local conditions, the small sewage disposal technology substantially without follow-up operation input and maintenance management of development investment
It is of great significance in Taihu Lake basin rural area.
It is found in actual observation, for rural area septic tank by using for a long time, cesspool sewage liquid level is constantly in outlet pipe
Road junction lower edge, whenever injecting one sewage mixture, the liquid for just having equal volume flows away from pipeline, therefore, rural area excrement
Pond water outlet is intermittent rather than consistent is constantly discharged.The sewage of septic tank outflow is generally directly injected into Soil Surrounding.
Research in terms of planting industry contamination control has been found that soil has very strong nitrification, the septic tank of ammonia nitrogen in high density dirty
Water is discharged after soil filtration may have higher nitrate nitrogen concentration, therefore nitrify spy using soil filtration water outlet nature
Property, structure, which is subsequently discharged artificial denitrification system, can effectively reduce cesspool sewage nitrogen concentration, compared with existing sewage disposal technology
Cost advantage is notable.
Before scale promotes above-mentioned technology, simulation indoors carries out system characteristic parameters value Optimization Work must can not
It is few, and simulating lab test should follow the natural emission equivalent of cesspool sewage first, currently, simulation sewage discharge generally passes through
It is artificially injected sewage operations, when research, needs to operate multiple experiment duplicated subsystems in intraday different time, people
Work water filling due to each duplicated subsystem inject liquid time differ, and injection rate can not also accomplish it is completely the same, to generate
Experimental bias influences experiment conclusion, and therefore, a kind of experimental provision of simulation rural area septic tank draining of urgent need is to realize experiment draining
Automation, improve experimental precision.
