Description
Technical field
The invention belongs to sewage treatment area, be specifically related to a kind of method and system of tide current wetland coupling electrochemical intensified denitrification and dephosphorization.
Background technology
Along with the fast development of economy and improving constantly of living standards of the people, quantity of wastewater effluent also constantly increases, so that the problems such as China's pollution of waterhead, body eutrophication and ambient water quality deterioration are on the rise.At present, the sewage disposal of China mainly depends on traditional centralized activated sludge process, although technology and technique are day by day ripe and perfect, but face the too high problem of Construction and operation cost, many economically underdeveloped areas can not build large-scale wastewater treatment plant at all, and many built sewage works are on the shelf because of the moving funds shortage, so that China only has 24% trade effluent and 4% sanitary sewage to enter after treatment water body.Especially for China vast Rural areas backward in economy, its sewage disposal present situation is more severe: 96% village does not have Sewage treatment systems, 3.2 peasant more than hundred million can not drink cleaning water, only be about 1% sewage and flow into after treatment water body, this ratio is far below developing country's average Rural areas wastewater treatment rate 18% of World Health Organization's report.From Tenth Five-Year Plan Period, the living environment that China just will realize cleanliness of villages and improve the peasant is as one of important goal of building Socialist New, yet passes by for many years, and the wastewater treatment rate of rural areas in our country is still very low.This explanation centralized sewage disposal pattern is effective for the big and medium-sized cities of high human settlements density, but for the Rural areas, the construction that it is high and operation and maintenance cost make it be difficult to promote.Therefore, be the construction process that further promotes the new rural area of Chinese society doctrine, the Sustainable development that ensures Ecological Environment, according to characteristics such as the backward in economy and source of sewage dispersions in Rural areas, the country sewage purification techniques of develop simple and easy to do, efficient economy, beautify the environment, distributing being processed on the spot become promote in China's rural development and the evolution institute must in the face of and the urgent important topic of solution.
The decentralized type sewage treatment technology is because its cheap cost has become the focus of disposing of sewage in present rural area.Traditional decentralized type sewage treatment system has: oxidation pond, septic tank and artificial wet land system etc.The oxidation pond visual aesthetics is relatively poor, and the nitrated removal of organic aerobic decomposition and nitrogen is not good.Septic tank mostly is the pre-treatment of Sewage treatment systems, but water outlet still has suspended substance, biochemical oxygen demand (BOD) (BOD), nitrogen (N), phosphorus (P) and the bacterium of higher concentration, can not directly enter water body.Wastewater treatment is a kind of ecological sewage purification techniques with controllability and through engineering approaches characteristics that artificially designs and build by the simulating nature wetland that has grown up since 20 century 70s, and the characteristics such as, good purification low with its less investment, construction operation cost have been subject to extensive concern in recent years.Especially tidal flow artificial wetland, it relies on the matrix pores suction that the saturated saturated surface periodical change of bed body produces in the operational process that atmosphericoxygen is forced a suction bed body, can strengthen wetland bed oxygen transmission quantity, significantly improve the nitrated clearance of organism aerobic degradation and ammonia nitrogen.Although tidal flow artificial wetland preferably reoxygenation ability can be strengthened the generation of nitrifying process, so that ammonia nitrogen farthest is oxidized to nitric nitrogen, yet this aerobic environment has but directly limited the generation of denitrification process, so that the nitric nitrogen of enriched in the water outlet of wetland bed system has directly limited its thoroughly removing total nitrogen.
The excessive discharging of phosphorus-containing wastewater is one of important factor of eutrophication, so sewage dephosphorization is an important topic of water treatment field always.The removal of phosphorus in artificial swamp is mainly by wetland plant absorption, the biochemical action of wetland microorganism and the processes such as absorption, complexing and precipitation of matrix.Numerous studies have shown that, the absorption of plant and the activity of microorganism are little to the removal contribution of phosphor in sewage, and the absorption of matrix and precipitation account for 70%～80% of dephosphorization total amount.And the main body filler of constructed wetland bed adopts building sand and gravel more, its to the lower adsorptive power of soluble phosphate so that artificial swamp is very low to the clearance of total phosphorus.Although have in recent years the multidigit scholar to screen respectively and researched and developed and multiple soluble phosphate is had filler than high absorption capacity, such as calcite and slag etc., but the problem such as these fillers of Chang Yinwei are difficultly collected, price is high and the life-span is short is so that still be restricted phosphatic removal in the wastewater treatment process.
Artificial swamp mainly relies on microbial process to the removal of organism and nitrogen, and microorganism active is with the differing greatly of season and temperature variation, so that it is larger affected by seasonal variation on the removal of organism and nitrogen in the wastewater treatment process.Therefore, exploitation can move throughout the year and be adapted to extensive weather especially the artificial marsh sewage treatment system of the northern area of China become gradually the focus that present scholars pay close attention to.
