Description

A kind of iron-carbon micro-electrolysis coupling submerged plant module and its application
Technical field
The invention belongs to black smelly/eutrophication waters to repair field, in particular to a kind of iron-carbon micro-electrolysis couples heavy water and plants Object module and its application.
Background technique
Due to the quick extensive style development of industrial or agricultural and the lag of sewage collecting handling rate, at present many rivers in China Stream, lake water quality deteriorate seriously, and a large amount of pollutants enter river, and the pollutants such as COD, nitrogen, phosphorus are exceeded in water body, river water Body pollution is serious, and water body occurs seasonal or black throughout the year smelly." black smelly " in river not only makes one to feel mood to people's stimulus to the sense organ It is unhappy, moreover, gas that black and odorous water distributes (vulcanization oxygen, ammonia etc.) can directly be detrimental to health , ?smelly water body in anoxic State influences fish and other aquatiles, normal growth and development in water body, it is a large amount of to will lead to aquatile when serious Death, river aquatic ecosystem destroy completely, seriously threaten drinking for river and lake itself ecosystem health and nearby residents Water security also greatly hinders the sustainable development of littoral industrial or agricultural.Therefore, black smelly, the improvement city water ring of urban river is eliminated Border quality is very urgent, and research and development are cheap convenient, and safe and efficient quick recovery technique is extremely urgent.
Water body under the comprehensive function of the factors such as physics, chemistry and biology, makes pollutant after being included in certain pollutant Concentration and quantity reduce, and so that contaminated water body is restored to the state before pollution, restore its normal ecological functions, this phenomenon It is called " self-purification of water ".So however, after a large amount of polluter is discharged into water body, water body self-purification ability is far smaller than the amount of being discharged into Afterwards, water body just generates black smelly.It has been that the larger molecular organics such as nitrogenous, carbon are degraded to by feeding microorganism first after water body is contaminated Small organic molecule is finally changed into water and CO2.With further degradation, the dissolved oxygen in water body is further disappeared, and works as water After body tends to anaerobic environment, anaerobe mass propagation.In an anaerobic environment, organic matter is decomposed and is generated greatly by anaerobe Amount contains odour, such as CH4、H2S、NH3Etc. other gases for having peculiar smell, these gases enter atmosphere after escaping the water surface, send out water body It is smelly.In addition, CH4、H2S etc. can carry slightly solubility particulate matter during escaping the water surface and enter water body, so that water body be made to black.Detest Oxygen environment will cause the heavy metals such as Fe, Mn in water body and be reduced, and FeS, MnS etc. are formed in conjunction with S, make water body blackening.At present The smelly mechanism of blackening is still not clear, but generally believes that black and odorous water has high organic pollution load, nitrogen, phosphorus, Fe, S, Mn and low DO, More than low transparency several features.
The current research to black and odorous water processing technique both at home and abroad mainly has physics (cutting dirt, water is changed in dredging), chemistry (to throw Add flocculant, add heavy metal fixative, strong oxidizer), biological (microorganism enhanced technology, biological oxidation of sediment technology, plant Recovery technique).Although single physics, chemistry, biological method can administer black and odorous water to a certain extent, there is such as Regulation effect is undesirable, cost is excessively high, generates the disadvantages of secondary pollution, regulation effect are difficult to ensure chronicity or deficiency.It compares Under, in recent years, bio-ecological process improvement is realized according to the transfer of imitative biological theory, conversion and degradation water pollutant to certainly The reinforcing and recovery of right boundary water body self-purification ability are the stable and long-acting important means for improving quality of water environment, just because of due to Bio-ecological process has high treating effect, and operating cost is cheap, project cost is lower, can improve phase with greening environment and landscape In conjunction with the advantages that, be most promising malodorous black water Treatment process.Structure while repairing black smelly/eutrophication water The aquatic ecosystem with complete nutrition level structure is built, the self-purification capacity and life of black smelly/eutrophication water are fundamentally restored State function, but still remain following problems: first is that bio-ecological process needs are carried out in the case where water body environment gradually improves, For example nutrient concentration, water transparency, pH value, the dissolved oxygen of water body severely exceed, and can seriously affect bio-ecological process pair The repairing effect of black smelly/eutrophication water；Second is that being easy by seasonal effect, plant growth is slow under low temperature, biodegrade effect Rate is very low,；Third is that most of Polluted Urban surface water C/N are lower, and have the COD for being difficult to be degraded by microorganisms, influence Microbial denitrogenation effect.
Summary of the invention
In order to overcome the disadvantages mentioned above and insufficient, the existing black smelly/eutrophied water treatment technology of solution of the prior art Present in regulation effect is undesirable, cost is excessively high, generates the problems such as secondary pollution, regulation effect are difficult to ensure chronicity, is same When overcome bio-ecological process that need to improve habitat, restrict technological deficiency by season and using carbon source, primary and foremost purpose of the invention exists In providing a kind of iron-carbon micro-electrolysis coupling submerged plant module.
Another object of the present invention is to provide the applications of above-mentioned iron-carbon micro-electrolysis coupling submerged plant module.
A kind of iron-carbon micro-electrolysis coupling submerged plant module, including submerged plant system and aerating system, the heavy water are planted Object system includes field planting basket and submerged plant, submerged plant is fixed in the field planting basket, submerged plant root is by iron carbon filler It wraps up and fixes, surrounding is surrounded by haydite after fixing, and the submerged plant is fixed in the field planting basket by haydite；The aeration System is underwater aeration or surface aeration.
