Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] In an embodiment of the present invention, a method for biologically purifying eutrophic water, the specific steps are:

[0026] (1) Cultivation of microorganisms: the raw materials of the microorganisms include 30-70 parts of microbial flocculants, 10-40 parts of composite enzyme preparations and 10-40 parts of composite microorganism preparations in terms of mass parts.

[0027] The microbial flocculant is prepared in the following way: Inoculate the sterilized ferme...

Abstract

The invention discloses a method for biologically purifying an eutrophic water body. The method particularly comprises the following steps: independently culturing a microbial flocculant, a compound enzyme preparation, and a compound microbial preparation by use of a fermentation tank culture medium; mixing the microbial flocculant, the compound enzyme preparation and the compound microbial flocculant in proportion to obtain a microbe, then adding water with 10 times of weight, uniformly mixing, and restoring the water body into a transparent state by adding a predetermined quantity of microbes to every ton of a target water area; restoring a submerged plant in the target water area to keep the water body in a stable and clear state; and adding an aquatic animal to the target water area to enhance the biological diversity of the water body and keep the ecological stability of the current water body. The method disclosed by the invention can be used for thoroughly improving the water quality and restoring the ecological balance of the water body by forming a multi-stage effect through the combined action of the microbe with a synergistic function, the submerged plant and the aquatic animal and has the advantages of easiness for operation, low cost, no biological side effect and no secondary pollution generation.

Description

technical field [0001] The invention relates to the field of water quality purification, in particular to a method for biologically purifying eutrophic water bodies. Background technique [0002] As we all know, the eutrophication of lake water and the prevention and control of algal blooms are worldwide problems. Generally speaking, there are two technical approaches: one is to reduce the water body pollutants, increase the self-purification ability of the water body, and reduce the nutrient level to an oligotrophic state; Inhibit algae cell aggregation and water bloom occurrence. Judging from the main action process of various technologies, they can be divided into several categories: physical method, chemical method, biological method and comprehensive method. [0003] Physical methods include external source sewage interception, drainage and flushing, sediment dredging, aeration and reoxygenation, mechanical algae removal, manual fishing algae removal, solenoid valve a...
