An open microalgae cultivation pond

Abstract

The invention relates to an opening type microalgae culture pond. Horizontal water discharging grooves are formed in upper parts of pond walls at two sides of the culture pond; horizontal water inlet grooves are formed in bottoms of the pond walls at two sides of the culture pond; channels are casted on outer walls at two sides of the culture pond; the channels are communicated with the water discharging grooves and the water inlet grooves in the culture pond; the culture pond is internally provided with a horizontal separation plate; an outer side edge of the separation plate abuts against the pond walls of the culture pond and is located between the water inlet grooves and the water discharging grooves; a plurality of through holes are formed in the separation plate; a plurality of conical flow guide seats are fixed on an upper end face of the separation plate; conical flow guide holes are formed in the flow guide seats and are communicated with the through holes in the separation plate; a plurality of oil cylinders are fixed on a lower bottom surface of the culture pond; piston rods of the oil cylinders penetrate through the pond bottom of the culture pond and are fixedly connected onto the separation plate. The opening type microalgae culture pond can realize automatic exchange of microalga at the upper part of the culture pond and microalga at the middle and lower parts of the culture pond, so that sufficient photosynthesis of the microalga at the middle and lower parts of the culture pond can also be realized.

Description

Technical field: [0001] The invention relates to the technical field of biological culture devices, and more specifically to an open microalgae culture pond. Background technique: [0002] Microalgae can effectively use light energy, CO2 and inorganic salts to synthesize proteins, fats, carbohydrates and a variety of high value-added biologically active substances. Microalgae can be cultured to produce health foods, food additives, feeds and other chemicals. Especially in recent years, with the development of bio-energy technology, certain oil-bearing microalgae have high oil production capacity (generally accounting for 20-60% of dry cell weight), high photosynthetic efficiency and short growth cycle. They can be used in saline soil, desert, Aquaculture in the sea has the huge advantages of not competing with food for land and people, and the characteristics of using carbon dioxide in factory exhaust gas as a carbon source. Countries around the world have regarded it as a very i...

AI Technical Summary

Problems solved by technology

The cells of most algae in the middle and lower parts are in weak light or dark areas, unable to obtain sufficient light, and the photosynthesis of cells is weak
