Abstract
The present invention relates to a method of cooperative control of alga in a water body comprising grass carp, cladophora and daphnia hyaline, which relates to a water treatment method and solves the problem of high operating cost and much of the by-products of the current alga control method. In the present invention grass carp is cultured in eutrophication water body with a culturing density of 20~100 g/m<3> and a single weight of 20~100 g; a floating net cage is arranged in the eutrophication water body, which is an open net cage made from stainless wire net having an aperture of 4~6 mm, besides, the four corners of the upper bottom of the floating net cage are provided with floater, by which the side walls of the floating net cage can overtop the water level by 0.2~0.4 m. The present invention is simple and easy, and can reduce the alga content and the trophic level in raw water of water plant effectively so as to solve the problem of that the eutrophication high algae-laden raw water affects the conventional treatment in current water plant, to reduce the cost and improve the water quality. The present invention make the best of the food habit difference between grass carp and daphnia hyaline, and comparing with the prior art, the present invention is simple and easy, economy and shortcut, and has high efficiency and convenient operation.
Description
Technical field
The present invention relates to a kind of water treatment method, be specifically related to a kind of method of utilizing algae content in the multiple fresh water hydrobiont Collaborative Control water factory eutrophic raw water.
Background technology
Body eutrophication is owing to the excessive water body effect that causes of nutritive substances such as nitrogen, phosphorus input, mainly shows as the hypertrophy of algae in the water, also follows the variation of a series of water quality and water ecology simultaneously, causes water transparency to descend water quality deterioration.Eutrophic raw water greatly influences the ordinary production of waterworks.
In existing algae-removing method, have with strong oxidizer and algicide to be chemical process except that the algae means, also having air supporting is the physico-chemical process of representative, and the physical method of Microfilter and membrane filtration or the like.The common advantage of chemical process, physical chemistry method and physical method is to remove algae efficient height, but deficiency is also respectively arranged.Medicament reaches except that Cutleriales chemical process to add, but may produce harmful by product in removing the algae process, thereby particularly the use of oxygenant causes that frond breaks and causes born of the same parents' intracellular toxin to discharge.Though method such as air supporting and membrane filtration does not have the by product problem, complicated operation, running cost are higher.
Summary of the invention
The objective of the invention is provides a kind of grass carp, bristle algae and daphnia hyaline multi-biology cooperated algae control method for solving running cost height, the by product problem how that existing algae control method exists.Method of the present invention is: throw in grass carp in eutrophication water, the injected volume of grass carp is every cubic metre of water body 20～100g, and the single cabrage amount of grass carp is 20～100g; In the water body of throwing in grass carp, place floating net cage, the aperture of floating net cage is the uncovered net cage that the Stainless Steel Cloth of 4～6mm is made, the length of floating net cage * wide * height is of a size of (1～2m) * (1～2m) * (1～2m), floating net cage upper base Corner Strapped float, make floating net cage sidewall exceed the water surface 0.2～0.4m, two of floating net cage internal fixation and parallel sidewalls, with vertical aperture, the end up and down be the nylon mesh of 1～2cm, about these two nylon mesh with the base respectively with the sidewall of floating net cage with go to the bottom and be stitched together, between two nylon mesh and the distance between the floating net cage sidewall that parallels with it be 30～35cm, apposition growth bristle algae on the wire side of nylon mesh, it is the transparent Magna of 10～50/L that the interior growth of floating net cage simultaneously has density.The transparent Magna of the present invention breeds growth in the floating net cage of manual manufacture, promptly with the symbiosis of bristle algae, thereby avoid ingesting of grass carp; The grass carp bristle algae that only can ingest only can grow the bristle algae, and keeps certain biomass in net cage.The present invention mainly is from ecological angle, utilize hydrobiological feeding habits and the relation of the food chain between them in the physical environment, reach controlling and removing algae, reduce the purpose of water nutrition level, thereby guaranteed the efficient of drinking water treatment, improved the biological safety that supplies water.The present invention united grass carp to the ingesting of bristle algae, transparent Magna to the removal of the filter food of algae, bristle algae to the water nutrition material, thereby reach algae content in the former water of control, reduce former water nutrition level, be beneficial to the processed conventionally purpose in waterworks.The present invention has simple, can effectively reduce algae content and trophic level in the raw water of waterworks, has solved the influence of waterworks eutrophication algae concentrated feeding water to conventional treatment process, has reduced production cost, has improved the advantage of producing water water quality.The present invention has made full use of the feeding habits difference of grass carp, transparent Magna.Compare with existing algae improvement method, the inventive method is easily gone, efficient is higher, economy is quick, be easy to management, can be in large-scale application.Comparatively speaking, by product is stablized, is not had in biological algae control method effect, and biggest advantage is that running cost is low, approaches zero, and this is to be energy derive with sun power because of the biological control effect.Its ultimate principle is to adopt the growth of special organism with the integral part in control algae or other food chains.Adopt multiple biology, utilize different interbiotic synergies to reach the Cutleriales that removes of stability and high efficiency.The index that the present invention reaches is: the water inlet total phosphorous is 0.05～0.1mg/L, and the water outlet total phosphorous is all the time less than 0.02mg/L, and average removal rate is 75.1%.Water inlet algae content is 2,000 ten thousand/L～5,000 ten thousand/L, water outlet algae content all the time 5,000,000/below the L, the algae average removal rate is 77.5%, the chlorophyll a average removal rate is 68.3%
