Problems solved by technology
[0004] In order to follow the basic principle that microalgae cultivation does not compete with agriculture for land, we usually choose to cultivate algae and refine oil on marginal lands such as beaches, saline-alkali lands, and sandy wastelands. However, these areas often lack electricity and heat, and no carbon dioxide industrial waste gas can be used.

Abstract
The invention relates to the fields of biomass electricity generation and heat supply, microalgae cultivation engineering, biodiesel refining and environmental protection, in particular to a production method of electricity generation and heat supply of algae cultivation and oil refining coupled with grass growing. The production method uses the marginal land with surrounded water source to plant energy grass which is used as main fuel to generate electricity and supply heat, and the generated electricity and heat are used for microalgae culture and processing, biodiesel refining and so on; and then biomass boiler flue gases and eutrophication water bodies are used as main raw materials to culture oil-bearing microalgae on a large scale, and the microalgae oil is used as a raw material to refine biodiesel. The production method is characterized in that electricity generation and heat supply of the grass growing ensure the electricity and heat required by the algae culture and oil refining, and self-sufficiency industrial waste gas of carbon dioxide, and the 'three wastes'( waste gas, waste water and industrial residue) and waste heat generated during electricity generation and heat supply and biodiesel refining are used as fertilizers of energy grass and as the raw materials and heat sources of microalgal culture, thereby reducing production cost and realizing clean production of biodiesel and treatment on the polluted water bodies.
Description
[technical field] [0001] The invention relates to the field of biomass power generation and heat supply, the field of microalgae cultivation engineering, the field of biodiesel refining and the field of environmental protection, and specifically relates to a production method for algae cultivation and oil refining coupled with grass planting for power generation and heat supply. [Background technique] [0002] Biodiesel is fatty acid methyl ester, which is clean and renewable energy. It uses oil crops such as soybean and rapeseed, oil palm, jatropha and pistachio and other oil forest fruits, oil aquatic plants such as "engineering microalgae" and animal oil , waste cooking oil, cottonseed oil and other liquid fuels are high-quality substitutes for petrochemical diesel. Biodiesel is a typical "green energy", with excellent environmental protection performance, good safety performance, good combustion performance, good lubrication performance, etc., and biodiesel itself is als...
