Embodiment 1

[0023] (1) Get 200 grams of montmorillonite, 110 grams of kaolin, and 110 grams of zeolite powder, and stir for 8-12 minutes under the stirring state of a 500r / min motor;

[0024] (2) After the appeal step is completed, add 2 grams of Bacillus subtilis and 2 grams of Rhodopseudomonas palustris, and stir for 25-30 minutes;

[0025] (3) After completing the above steps, add 110 grams of polyaluminum chloride, add 40 grams of polyacrylamide and stir for 15 minutes to prepare a compound water purification material for removing eutrophication from water bodies by blue-green algae.

[0026] Appeal is being implemented

Embodiment 2

[0028] Practical steps for the removal of cyanobacteria in water eutrophication and elimination of biological compound water purification agent: Take the cyanobacteria removal in water eutrophication and elimination of biological compound water purification agent prepared in the example of the appeal and dilute it into a water agent at a ratio of 1:30, and wait until it is completely dissolved After that, stir continuously at 80-100r / min for 15-20 minutes without interruption. After completing the appealing steps, a bio-composite water purifying agent for removing eutrophication from water bodies to be used for blue-green algae is prepared.

Embodiment 3

[0030] Cyanobacteria removal in water eutrophication elimination biological compound water purification material flocculation experiment on cyanobacteria bloom: 1000ml cyanobacteria bloom (absorbance after 30 times dilution is 0.538) is added in different amounts of cyanobacteria to remove water eutrophication elimination agent, in Samples were taken at 2cm below the liquid surface, and the absorbance of the samples was measured at a wavelength of 600nm to calculate the removal rate of cyanobacteria blooms. In the following table 1 data, the amount of cyanobacteria remover increases with the increase of the usage rate, and the removal rate increases. When the usage rate is 170ppm, the removal rate reaches a maximum of 99.58%, and the removal rate tends to be stable as the usage rate increases.

Abstract

The invention discloses a biological compound water purification material for removing natural water eutrophication by blue-green algae. The removal rate of bloom-forming blue-green algae by the biological compound water purification material for removing natural water eutrophication by blue-green algae is up to 99.7%, the degradation rate of total phosphorus is up to 98.1%, and the degradation rate of ammonia nitrogen is up to 74.36% after placing for 17 days. The total phosphorus ammonia nitrogen degradation effect is good, the application range is wide, bio-degradation is easy, and secondary pollution to the environment is avoided. Blue-green algae is removed, necessary growth elements required by growth of the blue-green algae are degraded, the problem of blue-green algae outbreak is solved, the inhibition effect on secondary development of blue-green algae after fading is achieved, the ecological environment of the whole water area is improved, and the environmental stability is maintained.

Description

technical field [0001] The invention relates to the technical field of purifying natural water bodies, and specifically designs a compound water purification material for removing eutrophication of natural water bodies by cyanobacteria. Background technique [0002] Along with human survival activities, excess nutrients such as nitrogen and phosphorus enter natural water bodies every year, resulting in eutrophication of water bodies. Eutrophication of water body will lead to algae blooms, which will cause algal blooms or red tides under suitable temperature conditions. In recent years, large freshwater lakes such as Dianchi Lake in Yunnan, Taihu Lake in Jiangsu, Chaohu Lake in Anhui, East Lake in Wuhan and Dianshan Lake in Shanghai have suffered serious cyanobacterial bloom pollution, and many lakes and reservoirs in the Yangtze River, the Yellow River and the middle and lower reaches have also occurred in succession. degree of cyanobacterial blooms. [0003] The main haza...
