Problems solved by technology

However, the current biological carrier method still has the following problems: 1) affecting the lake water landscape; 2) the application process has a certain impact on the structure and use of the water ecosystem, such as the carrier used in polluted water will affect the water storage of the lake and flood discharge; 3) Biofilm technology requires relatively high costs in terms of infrastructure and operation
[0020] 1) High cost and great impact on the environment
Such as chemical remediation, sediment dredging, etc. are prone to produce secondary pollution, causing damage to the lake ecosystem
[0021] 2) The repair effect is difficult to last
Although microbial and chemical methods can quickly improve water quality, the repair effect is often unsustainable because they fail to substantially improve the self-purification ability of lake water. When pollutants enter the water body, the water environment is damaged.

Embodiment 1

[0053] Test fish tank: After cleaning the fish tank with boiling water, lay 7cm high lake bottom mud or fine sand on the bottom.

[0054] Composite ecosystem construction method:

[0055] a. Preparation of submerged plants: Take bitter grass seedlings, clean them, cut off the long roots of the plants, leave a little root of the plants, rinse with distilled water, mix with crushed kitchen waste, 5% EM compound bacterial solution, 3% seaweed The GA3 of Sodium Oxide and 75mg / L is mixed and made into the gel that comprises the bottom of the rhizome of Chickweed;

[0056] b. Put the gel containing the bottom end of the rhizome of Erythrina balsamicus into the hollow conical artificial reef made of volcanic rock, then put the conical artificial reef into 2wt% calcium chloride solution for curing reaction, and stop the reaction after curing That is, the body of bitter grass reef is obtained;

[0057] c. Insert the tip of the cone-shaped bitter grass reef body into the bottom mud; t...

Embodiment 2

[0061] Field test site: about 1.5m deep, with an area of ​​15m 2 In the pond, the water body is eutrophic, the initial concentration of total phosphorus is 1mg / L, and the initial concentration of ammonia nitrogen is 5mg / L

[0062] a. Preparation of submerged plants: Take bitter grass seedlings, clean them, cut off the long roots of the plants, leave a little root of the plants, rinse with distilled water, mix with crushed kitchen waste, 5% EM compound bacterial solution, 3% seaweed The GA3 of Sodium Oxide and 75mg / L is mixed and made into the gel that comprises the bottom of the rhizome of Chickweed;

[0063] b. Put the gel containing the bottom end of the rhizome of Erythrina balsamicus into the hollow conical artificial reef made of volcanic rock, then put the conical artificial reef into 2wt% calcium chloride solution for curing reaction, and stop the reaction after curing , to get the body of bitter grass reef;

[0064] c. Insert the tip of the cone-shaped bitter grass r...

Abstract

The invention discloses a eutrophic water body repairing compound ecosystem construction method and an artificial reef. In construction, a tip of the artificial reef with submerged plants is insertedinto water body bottom mud, alga organisms are put into a water body after the submerged plants grow stably and appropriate oxygen exposure is performed, biological compound bacteria are put into after the alga organism population is stable, and appropriate maintenance is performed until a system is complete. The artificial reef comprises a hollow artificial reef body made of volcanic rock, wherein gel containing plant root stem bottom ends is added into the hollow position of the artificial reef body, the surface of the artificial reef body is coated with a solidified layer of a sodium alginate gel solution, the hollow artificial reef body is optimally in a conical shape, and the conical tip is inserted into the bottom mud. The compound ecosystem disclosed by the invention has the advantages of simpleness in construction operation, short period, low cost, strong applicability, ability in keeping the water body clear to the bottom for a long time, certain kitchen garbage treatment capability and certain capability in ecologically breeding loaches with high nutritional value.

Description

【Technical field】 [0001] The invention relates to a method for constructing a complex ecological system for repairing eutrophic water body and an artificial reef, belonging to the technical field of environmental protection. 【Background technique】 [0002] Eutrophication of water body refers to the enrichment of nitrogen and phosphorus nutrients in water body under the influence of human activities, causing the rapid reproduction of algae and other plankton, the decrease of dissolved oxygen in water body, the mass death of fish and other organisms, and the deterioration of water quality. Phenomenon. Since the 1980s in my country, due to rapid economic development and relatively lagging behind in environmental protection, many lakes and reservoirs have entered a state of eutrophication, or even severe eutrophication, such as Dianchi Lake, Taihu Lake, West Lake, East Lake, South Lake, and Xuanwu Lake. , Bohai Bay, Laizhou Bay, Jiulong River, Huangpu River, etc. In 2014, a sur...
