Device and its application method.
Background technology
Taihu Lake basin is as regional economy one of area of prosperity the most, and in recent years, it is fast that rural people occupies living standard
Speed is improved, the increasingly urbanization of its life style, and the discharge of a large amount of undressed sanitary sewages causes rural environmental pollution level
Greatly improve, rural scattered domestic sewage turn into Taihu Lake basin nitrogen and phosphorus pollution important sources, thus, Taihu Lake basin by
Step carried out domestic sewage in rural areas administer and treatment facility construction, using biochemistry --- eco-treatment technology as 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., at present, conventional process treating capacity account for rural area and lived dirt
More than the 80% of water process total amount.However, effective operation of rural domestic sewage treatment facility is one long-term engineering, due to fortune
The problems such as row expense and treatment facility are safeguarded causes existing a large amount for the treatment of facilities not run normally, and happy waits is flowed to Taihu Lake
Found after the running situation investigation of 210, domain rural domestic sewage treatment demonstration project, about 8% never runs, remaining engineering
Once there is the phenomenon that can not normally run.Therefore, the input of rural domestic sewage treatment very well equipped is being set up
And before administrative mechanism, suit measures to local conditions, development investment is small, sewage disposal technology substantially without follow-up operation input and maintenance management
It is significant in Taihu Lake basin rural area.
Research in terms of planting industry contamination control has been found that soil has very strong nitrification, therefore high strength ammonia
The sanitary wastewater of nitrogen enters irrigation canals and ditches after soil filtration may have higher nitrate nitrogen concentration, by being carried out to follow-up water outlet
Anaerobism disposal, addition are easy to the artificial construction of the denitrification environment such as the carrier of denitrifying bacterium growth, form effective denitrification and take off
Nitrogen place, makes soil be combined the natural attenuation transformation and artificial denitrogenation technology of nitrogen pollutant, so as to be formed because of ground
Suiting measures to different conditions, investment it is small, substantially without follow-up operation input and maintenance management denitrification treatment technology.
Before scale promotes above-mentioned technology, simulation indoors carries out system characteristic parameters value Optimization Work must can not
Few, at present, simulation sewage discharge is general by being artificially injected sewage operations, it is necessary in intraday different time pair during research
Multiple experiment duplicated subsystems are operated, and are so not only bothered, can also be produced experimental error, shadow is caused to simulated experiment result
Ring.Therefore, it is badly in need of a kind of experimental provision of the unpowered denitrogenation of rural area cesspool sewage with water distribution uniformity function and carries out correlation
Experimental study, for formed suit measures to local conditions, invest it is small, put into substantially without follow-up operation and the rural area cesspool sewage of maintenance management is de-
Nitrogen treatment technology provides theoretical foundation and characteristic parameter.
The content of the invention

It is：Comprise the following steps：
Step 1: injecting septic tank former state water into water-locator (1) by water injection pipe (11), due to the interior script of water-locator (1)
Full of septic tank former state water, therefore when injected slurry volume is V septic tank former state water, have the septic tank former state water of suitable volume
Flowed out by water distributor (12), depth, the body peak height all same of each water distributor (12) insertion water-locator (1), therefore note
The septic tank former state water volume for entering each water distributor (12) is identical, and each septic tank former state water test bottle (2) is injected in the same time
The septic tank former state water of same volume, is easy to several experiments to carry out simultaneously；
Step 2: being nitrified in the presence of earth pillar of the septic tank former state water in septic tank former state water test bottle (2), then from water inlet
Mouth (32) is injected into nitrogen rejection facility (3), and liquid flows through the denitrifying bacterium carrier (36) in compartment (35), denitrifying bacterium carrier
(36) denitrifying bacteria on carries out denitrification denitrogenation to liquid；
Step 3: liquid flows through each compartment (35) successively, repeatedly through water hole (37a) and cross water space (37b), fully with
After denitrifying bacterium carrier (36) contact, flowed out by delivery port (33).
