Description
Technical field
The utility model patent relates to sewage treatment area, is specifically related to a kind of intermittent water inflow soil-plant nitrogen rejection facility.
Background technology
China Environmental State Bulletin shows in recent years, and it is permanganate index, petroleum-type and ammonia nitrogen etc. that national surface water and seven big flood owners want contamination index.Lake, Taihu Lake height manganate index, total phosphorus year, average reached III class, IV class water quality standard respectively, but seriously polluted because of total nitrogen, lake body water quality is bad V class, is in the moderate eutrophic state.Huan Hu river, Dian Chi is serious pollution, and main contamination index is an ammonia nitrogen.Exceeding standard of nitrogen content more and more becomes the restrictive factor that causes or quicken body eutrophication in the water body.
Along with country to industry, the attention that pollutes of enterprise's point source sewage discharge, development climax period has been experienced in the construction of municipal sewage treatment facility, build tens of sewage works every year on average, China's point source waste water control wins initial success, but total amount of pollutants discharged is not seen obvious minimizing.The polluted by nitrogen that is caused by face source agricultural fertilizer and sanitary sewage becomes the main polluted by nitrogen source of storehouse, lake body eutrophication gradually.To the improvement of sanitary sewage, the method that developed country generally adopts is centralized sewage work.For the amount of the pollution substance that reduces the Jiang Huchuan that enters Britain Thames, the European Rhine, U.S. Homewood canal and Mississippi, Japan and river such as Duo Mo river, government has strengthened the construction dynamics of municipal sewage plant.In addition, the country that adopts distributing to handle day by day increases.For example, Brazil, Sweden and North America etc.Japan has carried out since the country sewage processing plan from 1977, the popularity rate that country sewage is handled has reached quite level, the nearly 7,000,000 small-sized domestic sewage purification devices of cover (being called purification tank) in the whole nation are among using, wherein the purification tank that uses after 1999 is paid attention to denitrification functions, but the manufacturing cost of purification tank is higher.Australia has developed " FILTER " system, and it utilizes sewage to carry out crop irrigation, by irrigate land handle after, utilize underground hidden pipe that it is compiled again and discharge.This technology nitric efficiency is not high, and exists the pipe drainage system cost higher, uses inconvenient shortcoming in the higher area of ground water table.The stabilization pond technology is applied to sewage disposal in the American-European countries, but nitric efficiency is not high.
Theory and practice shows that all traditional sewage disposal technology nitric efficiency is low, and the design of treatment facility and operational management depend on existing experience, do not form complete theory, lack perfect mathematical model and instruct construction and production, and capital construction and working cost height.Therefore, seek low cost, high efficiency denitrogenation of waste water technology is extremely urgent with the pressure that alleviates body eutrophication.
The biological-ecological measure is to utilize hydrobiological vital movement, and 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.Ecological engineering denitrogenation approach comprises absorption, absorption, volatilization and nitrated, denitrification etc.Biological-ecological engineering cost comparatively speaking is lower, and is energy-conservation, and non-secondary pollution is one of main research tendency of denitrogenation of waste water.Technology commonly used has: waterplant recovery technique, chinampa technology and preposition storehouse technology etc.At present, many investigators are in line with the principle of energy-saving and environmental protection, research and development around efficient denitrification biological-ecological type novel process, carried out the exploration of aspects such as filler selection, system design, crop screening and process simulation, but system's nitric efficiency is low and problem such as obstruction, need further research, 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 the road of Sustainable development, provide necessity and effective technical guarantee, can obtain good economic benefit and social benefit for solve the body eutrophication problem from now on from the source.
Summary of the invention
The purpose of this utility model is to break out unusually at the routine that exceeds standard and cause thus of nitrogen content in the water body and the algae of unconventional property, a kind of biological-ecological moldeed depth degree nitrogen rejection facility is provided, can be lastingly and progressively bring into play ecologic effect when removing in the water nitrogen safely, promote stream entering lake and lake body to return and recovery to optimum healthy direction, and cost is low, energy-conservation, non-secondary pollution.
For realizing such purpose, technical solution adopted in the utility model is a kind of intermittent water inflow soil-plant nitrogen rejection facility, this device adopts right cylinder, and it is made of cylindrical shell, water-in, water outlet, level pipe, extraneous phase siphunculus and soil sample and interstitial water thief hatch; The water inlet is in the top of cylindrical shell, and water outlet is positioned at the bottom of cylindrical shell, is provided with level pipe in the cylindrical shell, porose on the level pipe, one end of extraneous phase siphunculus meets at right angles with level pipe and communicates, and the other end is opened on the cylindrical shell, also is provided with soil sample and interstitial water thief hatch on cylindrical shell.
Water outlet is positioned at the device bottom, and system's water outlet can insert the surface current artificial wetland as required.
Said level pipe is by extraneous phase siphunculus and cylindrical shell exterior in the utility model, the mouth of pipe place of extraneous phase siphunculus clogs with soft rubber ball, the soft rubber ball that can pull up extraneous phase siphunculus during obstruction carries out back flushing, the even cloth of level pipe hole, so both help the reoxygenation of device and the implantation of microorganism, and can avoid the formation of dead water region in the body again.
Said soil sample and interstitial water thief hatch can be provided with by longitudinal interval 15cm on cylindrical shell in the such scheme, and the mouth of pipe place of soil sample and interstitial water thief hatch clogs with soft rubber ball, and angle is 90 ℃ between extraneous phase siphunculus and the thief hatch.
When device of the present utility model used, filling hypothallus in cylindrical shell, said hypothallus adopted gravel, river sand and flyash etc. to mix by a certain percentage.Plant waterplant on the hypothallus, waterplant is adopted plantation separately or mixes plantation.
The utility model single assembly nitrogen removal rate can reach 70%-80%, and its treatment effect is better than prior art and owing to adopt from stream mode, running cost is low.
Innovation part of the present utility model is the selection of ecological bed design and waterplant and assembled unit, efficiently solves the problem of device obstruction and reoxygenation difficulty, possesses the advanced nitrogen function simultaneously, and the performance ecologic effect.The utility model also has does not need power, and operation is simple, and 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.
