Description
Technical field
The present invention relates to water bloom pollution environmental improvement technology, more specifically, relate to a kind of eutrophication fresh water water body algae hypertrophy that is used for suppressing, prevent and eliminate the plant leaching solution based compound algistat that fresh water bloom takes place.
Background technology
At present, one of natural water body eutrophication great problem of environmental pollution of having become the world and being faced.In China; Freshwater lake, reservoir eutrophication problem are very serious; Except Dian Chi, Yunnan, Taihu Lake, Jiangsu and Chaohu, Anhui three big freshwater lakes have taken place serious blue-green alga bloom pollutes, blue-green alga bloom contamination phenomenon has in various degree also all taken place in many lakes of the Changjiang river, the Yellow River middle and lower reaches and the reservoir in succession and detected the existence of algae toxin.Fishes and shrimps disappear basically in the part lake, and replace the tiny organism monoid of dwelling of all kinds of ends of adapt to polluting, and the color of water body in lake, smell all have deterioration in various degree, and the sewage body is received in part lake even become.The geographical position in many well-known lakes is in big or middle surrounding city, and their pollution causes the urban look quality to descend, and has had a strong impact on these regional residents' physical and mental health.Water pollution causes lake and littoral bio-diversity thereof to descend, more particularly to mankind's loss of species useful or that potential value is arranged.These lake and reservoirs all are important drinking water sources simultaneously, and the algae toxin that discharges after the algae death is degraded slowly in natural water, thereby hidden some dangers for to human health.Therefore, in the face of the natural fresh water body eutrophication degree increasingly sharpens and blue-green alga bloom breaks out more and more frequent situation, water bloom of water body control is very urgent.
The technical method of the growth of control fresh water eutrophication algae, improvement water bloom pollution concludes to get up mainly to comprise: nutraceutical inflows such as (1) control nitrogen, phosphorus at present; (2) physical method is administered; (3) chemical method control; (4) ecological method control; (5) biological method control.Wherein controlling nutraceutical inflows such as nitrogen, phosphorus mainly is to prevent human various unreasonable activities, reduces and cut-out nutritive salt source and passage, thereby reaches control waters algal grown and water bloom pollution improvement.Physics improvement method is that pollutant is transferred to other place, thereby reaches control waters algal grown and water bloom pollution improvement, but pollutant itself does not obtain radical cure, therefore significant limitation is arranged, and cost is very high, should not advocate on a large scale.The chemical harnessing method is with algicides such as copper sulphate, chlorine dioxide the waters algae to be killed; Reaching control waters algal grown, but this method makes the matter worse to the waters sometimes, and can make increases the novel chemical substance that influences healthy fish in the water; Can bring secondary pollution, should not advocate.Ecological treatment method is to reduce the nitrogen phosphorus in the water body through planting aquatic wetland plant; Administer to reach control waters algal grown and water bloom pollution, this method is a kind of effective ways of long-term prevention, but this method enforcement engineering is huge; Consuming time longer; Be difficult to see effect in a short time, and also have the problem of introducing biomass, promptly the bioenergy in a certain how much quantity of specific bodies of water introducing makes water ecosystem be unlikely to be destroyed.Seriously influence because water ecosystem itself is had at the excessive introducing other biological of the specific bodies of water.
The growth of control fresh water eutrophication algae, improvement water bloom pollution, the method for advocating in academia at present is a biological control method.Biological control method not only has the efficient height, cost is low and remarkable advantage such as non-secondary pollution, and the harmony between man and nature development of advocating with the world today is perfectly in harmony, so this technology also becomes the direction of current water environment Study on Technology exploitation.Adopt the public technology of biological method control eutrophic water algal grown, improvement water bloom pollution to have at present:
1, bio-stimulant bioremediation technology.This technology is through the required ferment of aerobic microbiological, oxygen part and vegetative activity stimulant being provided, promoting aerobic microbiological digestion peptizaiton, quicken to remove the organic pollutant in the sewage, promote the water body dissolved oxygen, sewage being handled.Bio-stimulant is a kind of to be a company's production by the U.S., and Taiwan can the agency of scientific & technical corporation of nation be sold in the China's Mainland, and another kind is that the water body purification of the ProbioticSolutions company development of the U.S. urgees to give birth to liquid (Bio-energizer is called for short BE).The composition of two kinds of products is approaching, mainly contains the organic composite nutrient things more than 50 kinds such as amino acid, urea, humus, enzyme, vitamin, yeast extract, does not contain microorganism.This technological weak point is that bio-stimulant also can promote algae photosynthesis when activating aerobic microbiological, though can not form wawter bloom, can make algal grown surpass check sample, causes water transparency to reduce.And effective time is slow, takes usually more than ten days.
2, fermentation straw extract (BFA) algal control.This technology is that the exploitation of the strong Microbial Technics Ltd in Shanghai is accomplished; Fermentation straw extract is formed through biofermentation by discarded rice straw; The biochemical complex liquid that contains the compositions such as amino acid, polysaccharide, multicomponent organic acid and vitamin of phenolic hydroxyl group, carboxyl and methoxyl group isoreactivity group; In order to improve activation of microorganism, strengthen effect to the polluted-water biological restoration.Defective that this is technological and deficiency, the one, only be applicable to the shallow-layer water body, then not too suitable for large-scale waters such as the Yangtze River Gorges.The 2nd, the algal control effect of this zymotic fluid has specificity, and anabena and beads algae are had remarkable inhibition effect, and to the inhibition DeGrain of chlorella, and is still waiting to confirm for the algal control long-term effect of practical natural water body.Experimental study shows in addition; There is not effect of algae restraint after the sterilization of fermentation straw extract; This shows that fermentation straw extract is that its contained microorganism plays main algal control effect, and this that is to say to apply it in the natural water can introduce external microorganism, has bio-safety hidden danger.Existing a lot of biological algae-inhibiting agent (the as above biological algae-inhibiting agent of the auspicious water scenery gardening in Hailin Co., Ltd patented product) commercially available and patented product all contains bacterium, and same problems of ecological security is arranged.
