The invention discloses a loop reactor, comprising photobioreactors and a stirring device, wherein the photobioreactors contain a microalgae nutrient solution and form an annular shape, the stirring device is used for stirring the microalgae nutrient solution to allow the microalgae nutrient solution to circularly flow in the annular photobioreactors. According to the invention, since impeller stirring is cooperatively used with an annular runway-like flexible plastic bag to compose a microalgae nutrient solution container, disadvantages of great energy consumption and complex pipeline arrangement of aeration stirring are overcome, and production cost is reduced; a circulation flow loop is composed by the stirring device and the flexible plastic bag, so adherence of microalgae on a wall is effectively prevented, and the problem of difficult cleaning of the reactor is improved.

The invention discloses a garden drainage mechanism capable of preventing clogging and a construction method thereof. The garden drainage mechanism comprises a drainage pipe with a water-permeable plate and a cache box located on one side of the drainage pipe; positioning rods are arranged on two sides of the upper end of the drainage pipe; waist-shaped holes are formed in the two ends of the water-permeable plate; a first positioning table and a second positioning table for fixing the positioning rods are arranged at the two ends of the drainage pipe respectively; the height of the first positioning table is lower than the height of the second positioning table; the positioning rods on the first positioning table and the second positioning table are sleeved with elastic members which arecompressed at the upper ends and are tightly pressed against the lower end surface of the water-permeable panel; a limiting plate for positioning the water-permeable plate is arranged at the top end of the drainage pipe; a discharge pipe communicating with the cache box is arranged on the drainage pipe on one side of the first positioning table; the lower end of the cache box communicates with thedrainage pipe through a water through pipe. The garden drainage mechanism has the advantages and effects that the water-permeable plate is dynamically mounted in the drainage pipe through the elasticmembers, so that automatic removal of foreign matter of the water-permeable plate can be realized, and the occurrence of water accumulation in a garden due to the clogging of the water-permeable plate is avoided.
