Abstract
The invention discloses a method for cooperatively controlling microcystis aeruginosa and purifying water quality by using Plagiognathops microlepis, hyriopsis cumingii, Bellamya aeruginosa and calamus, and belongs to the technical field of water quality purification. The method comprises the following implementation steps: 1, selecting a specific eutrophication water area; 2, putting the hyriopsis cumingii into a net bag of a continuous ecological floating bed; and 3, throwing the Plagiognathops microlepis and the Bellamya aeruginosa into the water respectively. The method is simple and practical, can control the microcystis aeruginosa on upper, middle and lower layers of the water and microcystis aeruginosa hypopus in bottom mud and achieves an effect of purifying the water quality; various types of organisms are added, so the biological diversity of the water is improved and balance of a water ecological system is promoted; the hyriopsis cumingii, the Bellamya aeruginosa and the Plagiognathops microlepis are caught, so a certain economic value is achieved; and the calamus can be harvested at fixed period and can be used for feeding animals or serve as paper-making raw materials, so secondary pollution is avoided.
Description
Technical field
The invention belongs to field of water quality purification, specifically, relate to a kind of fish, two kinds of zoobenthos and a kind of emergent and combine control algae and method for purifying water, more particularly, relate to a kind of thin squama silver xenocypris, hydriopsis cumingii, Bellamya Aeruginosa Reeve, calamus Collaborative Control microcystic aeruginosa and method for purifying water, belong to water-treatment technology field.
Background technology
Lake is one of important water resources of China, for the mankind provide irreplaceable ecology and social service function.But China's lake eutrophication is on the rise.The most obvious feature instantiation of lake eutrophication is algae " overgrowing " and algal bloom, and therefore, the excessive algae of removing in eutrophication water is an importance in eutrophication control.Microcystic aeruginosa is the modal algae kind of algal bloom, quantity and the outburst frequency are preponderated (Gao Xueqing etc., Nutrient Energetics of Microcytis Aeruginosa is studied, Peking University's journal, 1994; Metallographic is bright, Chinese Lakes eutrophication (), (two). Chinese Lakes environment, Maritime Press, 1995).Therefore, how to control microcystic aeruginosa and become the difficult problem that vast researcher is solution lake eutrophication.In recent years, non-classical biomanipulation has been widely used in lake eutrophication improvement, and achieves good effect.As China Patent No. 200710071817.8, disclose the patent of invention that a name is called " silver carp, bighead and cladophora united algae control method ", the method of this invention is: in eutrophication water, throw in silver carp and bighead, and in water body, the input density of silver carp and bighead is 60 ~ 100g/m
3, the input ratio of silver carp and bighead is 3:1 ~ 4:1, and single cabrage amount of silver carp or bighead is 60 ~ 200g; The floating net cage that length × wide × height is of a size of 1 ~ 2m × 1 ~ 2m × 1 ~ 2m is placed, apposition growth bristle algae on net cage in eutrophic water body.This invention make use of silver carp and the bighead filter food to eutrophic water algae remove and bristle algae to the removal of water nutrition material, thus reach and control algae content in former water, reduce former water nutrition level, be beneficial to the processed conventionally object of tap water.And for example China Patent No.: 200710144842.4, disclose a name and be called a kind of patent of invention utilizing zooplankton and filter-feeding fish series connection to remove the method for algae, the method of this invention is: be together in series by least two storing facilities of waters, then algae-containing water is flow through each storing facilities of water successively, hydraulic detention time in each storing facilities of water is 1 ~ 3 day, zooplankton or filter-feeding fish is alternately put in a suitable place to breed in adjacent two storing facilities of waters, putting zooplankton in a suitable place to breed is take Microalgae as the Daphnia magna of eating, fish in the storing facilities of water of putting zooplankton in a suitable place to breed are cleared up away completely or throw in predacious fish simultaneously, the storing facilities of water stocked carp of putting filter-feeding fish in a suitable place to breed is silver carp, bighead or only put silver carp in a suitable place to breed, silver carp breeding density is 40 ~ 200g/m
3, the single tail fish of silver carp is heavily 60 ~ 500g, and bighead and silver carp breeding density are than being 1:3 ~ 1:5, and the single tail fish of bighead is heavily 60 ~ 500g.This invention effectively can remove the algae in natural water body.
But by piscine organism algae control technology educational circles exist larger dispute, on the one hand, fish excessively put the eubiosis may destroying water body in a suitable place to breed, the ecosystem of water body is damaged; On the other hand, fish can not control the blue-green algae of each water layer and N, P content reduced in water body.
Summary of the invention
the technical problem that 1, will solve
The problem of disputing on is there is for utilizing the biological microcystic aeruginosa that processes in prior art, the invention provides thin squama silver xenocypris, hydriopsis cumingii, Bellamya Aeruginosa Reeve, calamus Collaborative Control microcystic aeruginosa and method for purifying water, the main body fish of traditional non-classical biomanipulation is replaced with one " environment-protective fishing "-thin squama silver xenocypris by it, and the zoobenthos-hydriopsis cumingii introduced in two kinds of lakes and Bellamya sp and a kind of emergent-calamus, by coordinating the effect reaching high-efficient purification eutrophication water between this, to realizing while the comprehensive control microcystic aeruginosa of water body different depths purification of water quality.
