Description
Technical field
The utility model relates to sewage treatment area, is specifically related to a kind of continuous water inlet vertical current and surface stream series connection plant deep denitrogenation device.
Background technology
Country begins nitrogen control to be included in the master control target from Eleventh Five-Year Plan, and water pollutant has increased ammonia nitrogen on the basis of chemical oxygen demand (COD), and topsoil has increased sulfur oxide and oxynitride on the basis of sulfurous gas.In " 12 ", need to carry out primary study to total amount and the regularity of distribution of nitrogen.
The polluted by nitrogen that face source agricultural fertilizer and sanitary sewage cause becomes the main nitrogen pollution sources of storehouse, lake body eutrophication gradually.To the improvement of sanitary sewage, the method that developed country generally adopts is centralized sewage work.Japan has carried out from 1977 since the rural sewage treatment plan, and the nearly 7,000,000 cover dispersed miniature purification tanks in the whole nation are using, and the purification tank that wherein uses after 1999 is paid attention to denitrification functions, but the manufacturing cost of purification tank is higher.Australia has developed " FILTER " system, and this technique nitric efficiency is not high, and exists the pipe drainage system cost higher, uses inconvenient shortcoming in the higher area of ground water table.In the American-European countries stabilization pond technology is applied to sewage disposal, but nitric efficiency is not high.
Biological
-The ecological property measure is to utilize hydrobiological vital movement, and the nutritive substance such as nitrogen, phosphorus in the water and other pollutents are carried out migration, conversion, degraded and the metabolism of artificial-strengthening, thus the method that water body is purified.At present research mainly concentrates on the preliminary study of engineering Application Research and denitrogenation dephosphorizing performance.It is one of focus of water treatment field research that plant and ecological engineering technology combine.Waterplant is the most obvious biological characteristic in the ecological engineering, and the purification function of ecological soil system is played an important role.The waterplant kind that artificial swamp is selected comprises floating plant, emergent and submerged plant.Different waterplant, its contaminant removal capacity is different.Floating plant is mainly used in nitrogen, phosphorus is removed and improve traditional stabilization pond efficient, and the submerged plant system also is in laboratory stage, and its main application fields is the advanced treatment after primary treatment and the second-stage treatment.
In addition, do not advocate the single plant of plantation in the plant denitrification system, in order to prevent owing to the factors such as weather, operation and insect pest cause the death of single plant, adopt the mode of mixed plantation, kind and structure by waterplant in the natural selection decision systems, screening advantage species, the way that improves simultaneously contaminant removal capacity begins to receive publicity.And because single treatment unit nitric efficiency is low, can't guarantee advanced nitrogen, many investigators are in line with the principle of energy-saving and environmental protection, around the efficient denitrification biology for this reason
-The research and development of environmental novel process, carried out the exploration of the aspects such as filler selection, combined system design, crop screening and process simulation, but system's nitric efficiency is low and the problem such as obstruction needs further research, and the aspects such as the stability of actual motion, reliability are still waiting to improve.From China's present case, carry out the further investigation of denitrogenation of waste water technology and the exploitation of application art, walk Sustainable Development Road, provide necessary and effectively technical guarantee for solve from now on the body eutrophication problem from the source, can obtain good economic benefit and social benefit.
Summary of the invention
The purpose of this utility model is to provide a kind of Continuous Flow combined type plant nitrogen rejection facility, can obtain higher nitric efficiency.
For realizing goal of the invention, technical solution adopted in the utility model is:
Continuous Flow combined type plant nitrogen rejection facility is made of surface stream wet land system and vertical-flow wetland system, and wherein, surface stream wet land system adopts ecological canal and brick mix structure, around it with the netted spacing ring of bamboo cane around, its inner gravel and ecological soil of filling; The water inlet of described surface stream wet land system enters with run by gravity by the grid that bamboo cane surrounds, its water outlet access vertical-flow wetland system; Described vertical-flow wetland system comprises waterwall, pod apertures, water-in, water outlet, level pipe, extraneous phase siphunculus and thief hatch, described water-in and water outlet are in respectively the upper/lower terminal of described vertical-flow wetland system, described level pipe is positioned at the inside of described vertical-flow wetland system, and even cloth hole, interval on the level pipe; One end of described extraneous phase siphunculus meets at right angles with described level pipe and communicates, and the opening of its other end is positioned on the wall of described vertical wet land system; Described thief hatch is positioned on vertical wall of described vertical wet land system.
Described vertical-flow wetland system can adopt a plurality of, for example three, is up and down alternating current attitude.
Described level pipe is by extraneous phase siphunculus and system's exterior, and the mouth of pipe place of extraneous phase siphunculus clogs and seals with soft rubber ball, and the soft rubber ball that can pull up extraneous phase siphunculus during obstruction carries out back flushing.Cloth hole, the even interval of level pipe so both had been conducive to the reoxygenation of device and the implantation of microorganism, can avoid again the formation of dead water region in the body.
The utility model has the advantage of the obstruction of effective solution plant nitrogen rejection facility and the problem of reoxygenation difficulty, possess simultaneously the advanced nitrogen function, and the performance ecologic effect.The nitrogen removal rate of the utility model single assembly can reach 75%-85%, and its treatment effect is better than prior art and owing to adopt from stream mode, running cost is low.The utility model relies on National Nature science project " quantification of ecological soil Sewage treatment systems greenhouse gases and generation mechanism research-Taihu Lake basin are example " (No.50908116), also having does not need power, operation is simple, the remarkable advantage that working cost and overhead charges are cheap is the face source sewage deep denitride technology that meets the practical situation of China.
