Problems solved by technology

Especially when the pollutants in the water cannot be completely separated from the water, on the one hand, it will directly affect the transparency of the water, thereby hindering the photosynthesis of aquatic organisms and plants in the water body, affecting the healthy growth of aquatic organisms, microorganisms, plants, etc., and making the number of plant populations in the water body On the other hand, the separated pollutants are difficult to collect and use because they sink to the bottom of the water, and will cause secondary pollution of the water body again. At the same time, with the gradual accumulation of sinking pollutants Affect the water depth, change the original water ecological environment, completely lose the use function of the water body, and affect the landscape and human life and health
[0003] The water ecosystem has been damaged to varying degrees, which will lead to poor self-purification ability of the water environment and a small environmental capacity

preparation example Construction

[0029] A method for preparing a water purifying agent for water body restoration, comprising preparing a carrier-modified green zeolite, and immobilizing composite probiotics in the carrier; the carrier is obtained by intercalating and modifying the green zeolite with a hydroxyl ion solution and then roasting , the above-mentioned hydroxyl ion solution includes zinc ions, zirconium ions, hydroxide ions and metasilicate ions. The preparation method uses the modified green zeolite with a multi-aperture structure as a carrier to immobilize composite probiotics, improve the stability and tolerance of the probiotics, the carrier has a large immobilization capacity and adsorption capacity, and the obtained water purifier can play a role in bacteria Group advantage and carrier adsorption performance, inhibit harmful bacteria, reduce water COD value, waste and heavy metal ion content, etc., high purification efficiency, to achieve the purpose of improving water purification efficiency,...

Embodiment 1

[0055] A water body ecological balance restoration method, comprising:

[0056] (1) transplant aquatic plants water lily, hornwort and foxtail algae in the water body;

[0057] (2) Prepare water purifying agent for water body restoration, and add 12kg / m to the water body 3 The amount of the water purifier should be sprayed once every 8 days;

[0058] (3) Mix volcanic ash and activated carbon with a weight ratio of 2:3.5 to prepare a deodorizing and decolorizing agent, and then add it to the water body at a rate of 6kg / m 3 Put the deodorizing and decolorizing agent in the dosage.

[0059] The preparation method of the water purifying agent for above-mentioned water restoration is as follows:

[0060] (1) Choose green zeolite with a particle size of 0.5-2cm, then place it in 75wt% ethanol solution and soak it for 30 minutes, then place it in pH 5 hydrochloric acid and soak it for 30 minutes, take it out, wash it twice with deionized water, and dry it ,spare;

Embodiment 2

[0068] A water body ecological balance repairing method, differs from embodiment 1 in that:

[0069] Step (1) transplanting aquatic plants hydrilla, water hyacinth and foxtail algae in the water body;

[0070] Step (2) The amount of water purifying agent used in water body restoration is 10.5kg / m in the water body 3 The preparation method of the above-mentioned water body repairing water purifying agent differs from Example 1 in that:

[0071] Step (2) in the hydroxyl ion solution, in terms of zinc ion, zirconium ion, hydroxide ion and metasilicate ion, the molar ratio is 1:0.2:1.9:0.3;

[0072] Step (4) Calcining the green zeolite obtained by intercalation modification at a temperature of 500° C. for 2.5 hours;

[0073] Step (6) selects photosynthetic bacteria, saccharomycetes and nitrifying bacteria, prepares and obtains thalline concentration and is 3.5 * 10 9 cfu / mL bacterial suspension, the concentration ratio of the above-mentioned photosynthetic bacteria, yeast and n...

Abstract

The invention provides a water ecological balance restoration method, which belongs to the technical field of ecological restoration, and comprises the following steps: transplanting aquatic plants into water, and adding a water purifying agent and an odor and color removing agent for water remediation into the water. The preparation method of the water purifying agent for water remediation comprises the following steps: preparing carrier modified green zeolite, and immobilizing composite probiotics in the carrier, wherein the carrier is prepared by performing intercalation modification on green zeolite by using a hydroxyl ion solution and then roasting, and the hydroxyl ion solution comprises zinc ions, zirconium ions, hydroxyl ions and metasilicate ions. According to the preparation method of the water purifying agent, the carrier can be promoted to form a multi-aperture structure, the adsorption capacity of the carrier and the immobilization amount of probiotics are increased, and the stability and tolerance of the probiotics are improved. The restoration method can inhibit the development of harmful flora, reduce the content of pollutants in the water body, improve the purification efficiency, improve and restore the ecological balance and self-purification function of the water body, increase the water environment capacity, reduce water body pollution and restore the ecological balance of the water body.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a water body ecological balance restoration method. Background technique [0002] With the continuous development of society, ecological and environmental issues have attracted increasing attention. Among them, water bodies are resources that human beings rely on for survival, mainly including lakes, rivers, oceans, and groundwater. The water quality is directly related to the survival of all living things. With the continuous development of industry and social economy and the continuous improvement of the level of urbanization, industrial wastewater, aquaculture wastewater, domestic sewage, etc. have directly or indirectly entered the major water body systems, resulting in increasingly serious water pollution in my country, resulting in such things as blue-green algae pollution and water quality. Nutritization and other serious pollution phenomena. Esp...
