Abstract
The invention relates to a technology for treating eutrophication pollution of a water body, in particular to a technology for controlling the pollution of blue-green algae, and belongs to the technical field of pollution control of water bodies. According to the technology, water hyacinth is controlled within a certain range of a water surface by utilizing a water body enclosure to control the coverage area of the water hyacinth on the water body, and the water body is purified by utilizing the biological characteristic of the water hyacinth. The technology is not only applied in long and narrow water areas (such as riverways), and but also used in large-area broad water areas (such as lakes); and for later-period recovery, a mechanized recovery mode is used, and only later-period fishing operation is performed effectively by using a professional ship, so that time and labor are saved. According to the technology, the recycling of the water hyacinth at the later period is considered, and the recovered water hyacinth is aired and can be used as high-quality organic fertilizers or methane fermenting raw materials and the like, so the technology is an ecological, environment-friendly and economic method for repairing water ecological environment.
Description
Technical field
The present invention relates to a kind of improvement body eutrophication pollution technology, particularly a kind of blue-green algae Pollution abatement technology belongs to water pollution and administers technical field.
Background technology
Along with the development of industrial society, human lives's aggravation, mankind's activity is increasing to the pollution of water body, and the eutrophication in river, river, lake has been global serious problems.Because industrial point-source pollution, widespread pollution from the overuse of fertilizers and pesticides in rural area and human lives's sewage discharge etc.; Cause a large number of nutrients accumulation in the water body, the numerous life of algae, the dark green muddiness of water colour; Even blackening is smelly; Have a strong impact on landscape effect and HUMAN HEALTH,, generally adopt overshot, physics to receive method, physico-chemical processes, biological harnessing method etc. in order to control algal grown.But these methods all exist in various degree expense high, produce ecological hazard, characteristics such as wayward.The improvement of eutrophication water needs to explore an effective method.
Herba Eichhorniae has another name called Herba Eichhorniae, water lettuce; It is swift and violent in containing organic hydrostatic, to grow, and especially prolificacy is extremely strong in the water body of eutrophication, in the waters that blue-green algae pollutes, cultures Herba Eichhorniae; Can absorb the total phosphorus and total nitrogen in the water body in a large number; And some allelochemicals of root system secretion, thereby the effect of purifying water body is played in the growth of control blue-green algae.
Summary of the invention
The object of the present invention is to provide the biological and ecological improvement method of blue-green algae in a kind of cost improvement eutrophication water low, simple and convenient, easy to implement.A large number of experiments show that water hyacinth has stronger inhibitory action to the growth of blue-green algae, mainly be by with nutrition such as algae competition nitrogen phosphorus and sunlight, and realize that by the allelochemical of root system secretion gram algae the gram algae acts on.In the Herba Eichhorniae whole growth cycle, all can absorb nitrogen phosphorus and the blue-green algae in a large amount of adsorbed water body in the eutrophication water in a large number.
According to technical scheme provided by the invention, adopt the water body enclosure that Herba Eichhorniae is controlled in the certain scope of the water surface, control its area coverage to water body, utilize the biological nature purifying water body of itself.
A kind of method of administering excess nitrogen phosphorus and blue-green algae in the water body, step is:
(1) placement of water body enclosure: the water body enclosure of buying put into needs the water administered, gets multiple spot along enclosure, on each some piling fixing, it is dark that the bamboo stake need be driven in the mud 0.5 ~ 1.5m; After the bamboo stake was fixing, the lateral part was fixed its colligation with steel wire; Carry out purse seine then, net bottom is sunk in the mud with gabion;
(2) plantation of Herba Eichhorniae: in the scope that the water body enclosure surrounds, directly be thrown into Herba Eichhorniae, the area of Herba Eichhorniae breeding is the 30%-70% of water body, and implantation time is selected the fine right up and down dusk; After the first plantation, the portion water cucurbit, according to the situation that becomes to live in the zone, is reseeded in fortnight because of former cause deaths such as transportation, transplantings;
(3) salvage: the Herba Eichhorniae breeding with its whole salvagings, was salvaged and is adopted the mode of mechanize to carry out after 2 ~ 3 months, adopted the ship of specialty to gather, or adopted cut mechanically; Herba Eichhorniae after the salvaging is handled through airing, carries out resource reutilization, as high-quality fertilizer material or biogas fermentation raw material.
When summer temp is too high, in time gather in the step (2) for the part of over growth.
Described water body enclosure is made up of two portions, and the one, the float band on bubbling through the water column, the one, undersurface netted skirt body portion, the counterweight part that the colony lower end is provided with.PVC cloth parcel is adopted on float band top layer, and inside is made up of a plurality of cavitys, is provided with porous plastics as float in each cavity, increases the buoyancy of enclosure, makes it float on the water surface.Netted colony part mainly is made up of fishing net, and design height is 1.5m ~ 2m.Adopt stone in order to counterweight in netted skirt body bottom.Its fixed form adopts timber to fix, and uses the timber multiple spot to fix at the two ends and the middle multistage of enclosure, prevents that stormy waves is excessive and is destroyed.The major function of water body fence device is to guarantee that Herba Eichhorniae does not outwards fly away, and plays the function of isolating hydrosphere relatively, helps the fishing job in later stage simultaneously.
The present invention has following advantage: the present invention no longer is confined to use (like the river course) in the long and narrow waters, in open water field of big area, also can use (like the lake); Gather for the later stage, the mode that the present invention uses mechanize to gather uses professional ship to carry out the later stage fishing job, more saves time, laborsaving, effective; The present invention has considered the recycling in Herba Eichhorniae later stage, and the Herba Eichhorniae of gathering is handled through airing, can be used as high-quality fertilizer material or biogas fermentation raw material etc., is the method that the economic again water ecological environment of a kind of ecological, environmental protective is repaired.
