The algal cultivating system of claim 1, wherein: annular scraper blade (32) include arc scraper blade (321), spacing arch (322) and spacing bolt (323), wherein annular scraper blade (32) constitute jointly by four arc scraper blade (321), single mid-mounting has spacing arch (322) under annular scraper blade (32), arc scraper blade (321) slide through spacing arch (322) and set up on annular plate (31), evenly seted up guide way (324) on annular scraper blade (32) lateral wall.

6. The algal cultivating system of claim 1, wherein: the upper end face of the base (2) is provided with a collecting tank (21) corresponding to the spray head (33), and a pressing block (22) is arranged inside the collecting tank (21) and on the outer wall of the breeding box (1).

7. The algal cultivating system of claim 1, wherein: adjacent from top to bottom link (44) and keep away from the one end of axis of rotation (43) and install cleaning plate (441) jointly, cleaning plate (441) keep away from the one end of link (44) and set up to the arc surface, and the arc surface of cleaning plate (441) supports and leans on breed case (1) inner wall.

8. The algae cultivation system according to claim 1, wherein: the method for cultivating the chlorella by the algae organism cultivating system comprises the following steps:

the first step is as follows: seedling throwing: pouring the prepared nutrient solution into the culture box (1), and putting artificially cultured chlorella seedlings into the nutrient solution in the culture box (1);

the second step is that: air supply: the rotating motor (42) is started to be matched with the connecting frame (44) through the rotating shaft (43) to drive the feeding circular tube (45) to rotate in the circumferential direction, and in the circumferential rotation process of the feeding circular tube (45), air is pumped into nutrient solution through the first groove (47) and the second groove (48) through the existing air pump to be used for photosynthesis of chlorella;

the third step: cleaning treatment: the existing drive drives the annular plate (31) to move upwards so as to scrape sundries such as chlorella on the outer side wall of the culture box (1) through the annular scraper (32), and the existing drive drives the annular plate (31) to move downwards after the scraping work is finished so as to wash the outer side wall of the culture box (1) through the spray head (33);

The fourth step: and (3) recording data: after the outer wall of the culture box (1) is cleaned, the chlorella is observed manually, and data recording is carried out on the growth condition of the chlorella until the culture of the chlorella is finished.
