Embodiment 1

[0045] An industrial ecological park model for intelligent supervision of cyanobacteria resource utilization. The invention uses GPS technology and N, P sensors and other technologies to quickly monitor the concentration of N, P and chlorophyll in the water quality of Chaohu Lake. At the same time, GPS technology can be used to locate each algal water separation Stations and blue-green algae transport vehicles to understand the whereabouts of blue-green algae resources, and through the establishment of mathematical models to grasp the water quality of Chaohu Lake, and early warning of blue-green algae outbreaks, online assessment, analysis and decision-making of Chaohu Lake environment.

[0046] The industrial ecological garden mode of the present invention includes the following contents:

[0047] (1) Factory for extracting phycocyanin and polysaccharide;

[0048] (2) Biogas projects that process raw materials such as cyanobacteria, livestock and poultry manure, and agricultu...

Embodiment 2

[0143] Experiments on the production of selenium-enriched organic fertilizers from cyanobacteria, fungus residues, and rice husks

[0144] 1 Preparation of selenium-enriched Bacillus subtilis Add 0, 15, 30, 45, 60, 90 mg / L of Na to the LB medium respectively 2 SeO 3 And 2%, 4%, 6% strain inoculum were cultivated. Utilizing the biotransformation ability of Bacillus subtilis to convert toxic and low utilization Na 2 SeO 3 The results show that the optimal concentration and inoculation amount for cultivating Bacillus subtilis are 30mg / L and 4%, respectively, and the organic selenium conversion rate reaches 80.57% under the optimal conditions.

[0145] 2 Mix the cyanobacteria, fungus residue, and rice husk in a ratio of 1:10:1, adjust the moisture content to 55-60%, and the final carbon-nitrogen ratio to 22-25, then put it into a 30L self-made compost bucket, compost The center and bottom of the barrel are drilled into the perforated PVC pipe and connected with an elbow. A blo...

Abstract

The invention provides an industrial ecological garden mode for intelligently supervising blue algae resource utilization, relates to the field of blue algae resource utilization, and aims to fully excavate and develop blue algae resources, purify and utilize blue algae in a graded manner, extract polysaccharide from salted-out supernatant and prepare pig feed from crude protein subjected to preliminary salting-out. Protamine obtained after secondary salting-out is used for purifying reagent-grade phycocyanin, and algae residues generated in production are used for biogas engineering. According to the method, the problem of pollution of residual algae residues after phycocyanin and polysaccharide are extracted can be solved, the problem of pollution of agricultural solid waste, livestock and poultry excrement, domestic sewage and the like can be solved, meanwhile, clean energy such as biogas can be generated, and biogas residues of biogas engineering can also be used for producing selenium-rich organic fertilizer for agricultural production of high-quality selenium-rich organic agricultural products.

Description

technical field [0001] The invention relates to the field of blue-green algae resource utilization, in particular to an industrial ecological park model for intelligent supervision of blue-green algae resource utilization. Background technique [0002] The eutrophication of Chaohu Lake is serious, and the frequent occurrence of cyanobacteria blooms has not been effectively curbed, and pollution control has a long way to go. The algae-water separation station located at the estuary of Tangxi River handles 3360t / d of blue-green algae and about 20t / d of blue-green algae mud. It is estimated to produce 2000t of algae mud per year, with a water content of about 95%, which is equivalent to 100t of dry algae. As far as Chaohu Lake is concerned, if 40,000 tons of blue-green algae dry powder is extracted every year as an example, it contains about 3,700 tons of nitrogen and 500 tons of phosphorus, which is equivalent to removing a huge amount of N and P from the lake, which is of gre...
