The zeolite-calamus constructed wetland sewage disposal system mainly comprises a tank body, a filler filled in the tank body, aquatic plants planted on the surface of the tank body as well as a water distribution pipe and a water collecting pipe distributed in the tank, the filler is mainly clinoptilolite, Nitrobacter opacus Sack and Nitrosomonas monocella Nelson are put into the filler, and the aquatic plants planted on the surface of the tank body are calami. The system and method adopt clinoptilolite which has good ammonia nitrogen removal effects to serve as the filler of the constructed wetland, in order to improvethe treatment efficiency of zeolite, special nitrifying bacteria under artificial culture are screened to regenerate the zeolite, and the constructed wetland system has advantages of high ammonia nitrogen removal capacity, low investment and running costs and simple operation.
Description
(1) technical field
The present invention relates to a kind of Zeolite-acorus calamus artificial wet land sewage treatment system, and utilize this artificial wet land system to handle the method for sanitary sewage.
(2) background technology
The Treatment for Reuse of low concentration sewage lacks at present a kind of not only economy but also treating method efficiently.If this sewage continues to use activated sludge process or other aerobic biological treatment processes,, and also need second pond precipitation, processing cost height, ammonia nitrogen removal weak effect in addition because of the low processing efficiency that makes of its organic loading is lower.
Artificial swamp (Constructed Wetland) is the nearly two a kind of wastewater treatment new technologies that grow up during the last ten years.Since preceding West Germany at first built artificial swamp, this technology was developed rapidly the domestic artificial swamp sewage disposal experimental project of also having built up before more than ten years in the U.S., Europe and some developed countries of Australia.
It is extremely complicated that wetland is removed mechanism of pollutants, is not to realize by single factors, but combines the factor of physics, chemistry and biological each side.The physics that artificial swamp is purified waste water, chemistry and bioprocess are except primitive reaction and interactional general utility functions with soil processing, the more important thing is in the wetland place that the flourishing root system of the long waterplant that has provides a large amount of breedings, perched for microorganism, the interaction of plant, microorganism, pollutent is the key point that wetland is removed pollutent.
Domestic similar techniques:
(1) 3 people's such as Deng Futang patent of invention " is the polluted water land disposal method of main stuffing with the light ceramic " (application for a patent for invention numbers 200510011013, publication number CN1765769A), be to be the polluted water land disposal method of main stuffing with the light ceramic, sanitary sewage enters ecological soil by water distribution system and handles bed after handling through equalizing tank.
(2) 5 people's such as Hu Hongying of Tsing-Hua University patent of invention " a kind of strengthened artificial wet land sewage water treatment method and system " (application for a patent for invention number 03150053.6, publication number CN1475448A), a kind of artificial marsh sewage treatment system that this invention provides, it is characterized in that: this system comprises the bottom and is covered with the rectangle pond body of impervious barrier all around, at pond body front end and 1/3rd punishment water distributor and water distributing area be not set, header and catchment area be set at the afterbody of pond body; In the body of pond, fill compounded mix by slag, red soil and soil ulmin preparation; The pond body first three/one section the plantation root system secrete the strong waterplant of oxygen ability, 2/3rds sections increments are big behind wetland, nitrogen, the waterplant that the phosphorus sorption is good.The structure water pipe that this invention relates generally to artificial swamp distributes and the floristics of plantation and the state of distribution thereof.
Also there is not at present document to relate to the relevant report of the bio-regeneration of the ammonia nitrogen removal of the specific nitrobacteria of artificial screening and zeolite.
(3) summary of the invention
The object of the invention provides a kind of economy, Zeolite-acorus calamus artificial wet land sewage treatment system, and the method for utilizing this artificial wet land system processing low concentration sewage efficiently.
The technical solution used in the present invention is:
A kind of Zeolite-acorus calamus artificial wet land sewage treatment system, mainly comprise the pond body, be filled in the intravital filler in pond, plant and be distributed in water distributor and header in the pond in the waterplant of surface, pond, described filler is mainly clinoptilolite, throw in Nitrate bacteria Nitrobacter opacusSack and Nitrite bacteria Nitrosomonas monocella Nelson in the filler, the waterplant of surface, pond plantation is a calamus.Used two kinds of autotrophy nitrobacterias are the known bacterial classification that bibliographical information is crossed, Nitrobacter opacus Sack, and its bacterial classification Chinese translation is opaque bacterium nitrobacter; Nitrosomonasmonocella Nelson, its bacterial classification Chinese translation is the unit cell Nitrosomonas.
Main points of the present invention are: adopting clinoptilolite is that the filler main component (accounts for the filler cumulative volume more than 50%, also can add the common filler that is used for artificial swamp in this area, as grit, gravel, red soil, soil ulmin etc.), and in conjunction with the very capable nitrobacteria of removal ammonia nitrogen---Nitrate bacteria Nitrobacter opacus Sack and the Nitrite bacteria Nitrosomonas monocella Nelson that filter out, improve processing efficiency, its internal structure adopts this area common structure to get final product, pond body with different shape that conventional artificial swamp has, water distributor, header, and the waterplant or the pleuston of the plantation of surface, pond; Clinoptilolite of the present invention has absorption preferably and the ability that exchanges ammonia nitrogen, after clinoptilolite absorption ammonia nitrogen reaches capacity, can't adsorb again and the exchange ammonia nitrogen, then can be by growing plants and microorganism in the wetland, consume the adsorbed ammonia nitrogen of zeolite, make zeolite obtain regeneration, go round and begin again like this, improve the ability of artificial swamp ammonia nitrogen removal.
Under aerobic conditions, NH
4 +Effect through Nitrite bacteria and Nitrate bacteria is converted into nitrite and nitrate, and under anaerobic, denitrifying bacterium is a nitrogen with reducing nitrate radical, and denitrifying bacteria belongs to the heterotroph facultative anaerobe.In fact, nitrification and denitrification can occur in wet land system simultaneously, not only has aerobic zone but also have hold concurrently oxygen and anaerobic zone in the wet land system under the water logging condition.Denitrifying bacterium then is the nature spontaneous growth, because of NH in the artificial swamp
4 +Effect through Nitrite bacteria and Nitrate bacteria is converted into nitrite and nitrate, has nitrite and nitrate to exist, and then denitrifying bacterium can the raised growth breeding.In artificial swamp as do not throw in the advantage nitrobacteria of artificial culture, the microorganism of occurring in nature growth then, the survival of the fittest, which type of microorganism all may breed, and wherein nitrobacteria does not form advantage, causes the efficient of removing ammonia nitrogen not high.
Packing volume consists of in the described artificial wet land system: clinoptilolite 65～75%; Red soil 15～25%; Soil ulmin 5～15%.Artificial swamp zeolite filler height is generally 1～1.5m, and the exchange capacity of ammonia nitrogen is 5～10kg/m
