NOVELTY - Rapid infiltration bed of sunlight greenhouse for improving matrix temperature comprises an infiltration bed, a matrix temperature raising system and a sunlight greenhouse. The infiltration bed and the matrix temperature raising system are arranged in the sunlight greenhouse. The infiltration bed comprises a main body filled with soil, a water distribution tank and a water collection tank distributed in the soil of the main body. The water collection tank is set below the water distribution tank. Two sides of the water distribution tank are provided with reinforced water distribution material.    USE - The rapid infiltration bed of sunlight greenhouse is useful for improving matrix temperature.    ADVANTAGE - The rapid infiltration bed: improves matrix temperature; enables the matrix temperature to be not affected by seasons; improves sewage treatment capacity in winter; has high purification efficiency, high effluent quality and simple structure; and can be operated in a stable and continuous manner.    DETAILED DESCRIPTION - Rapid infiltration bed of sunlight greenhouse for improving matrix temperature comprises an infiltration bed, a matrix temperature raising system and a sunlight greenhouse. The infiltration bed and the matrix temperature raising system are arranged in the sunlight greenhouse. The infiltration bed comprises a main body filled with soil, a water distribution tank and a water collection tank distributed in the soil of the main body. The water collection tank is arranged below the water distribution tank. Two sides of the water distribution tank are provided with reinforced water distribution material. A water distribution pipe is arranged in the water distribution tank. Fillers are arranged on the four sides of the water distribution pipe in the water distribution tank. The ground of the main body is planted with plants. The matrix temperature raising system comprises a fan and a pipeline. The fan is arranged on one side of the ground infiltration bed. The pipeline is arranged in the main body of the infiltration bed and the two ends of the pipeline extend out of the surface of the main body. One end of the pipeline is connected to the fan and the other end is connected with the atmosphere. The pipeline in the infiltration bed main body is arranged below the water distribution tank and above the water collection pipe. The sunlight greenhouse comprises a framework, a film and a straw mat. At least one layer of the film is paved on the framework, and one layer of straw mat is coated on the film. An INDEPENDENT CLAIM is also included for operation of the rapid infiltration bed of sunlight greenhouse, comprising: (a) covering the sunlight greenhouse above the infiltration bed from 8th October to 24th October until the weather is warm from 5th, April to 1st May in the next year, (b) turning on the fan at 10 am on a sunny day, such that the high temperature air in the sunlight greenhouse is introduced underground after blasted by the fan, circulating the high temperature in the pipeline in the infiltration bed, completely exposing to the matrix, such that the temperature of the matrix is constantly raised, turning off the fan at 4 pm, maintaining the infiltration bed at a specific temperature to prevent the plant from cold injury, to improve the activity of the enzyme, and to purify the sewage under comprehensive purification function of soil-microorganisms and plan system, (c) turning on the fan at 11 am on a cloudy day, and turning off the fan in the afternoon, and (d) covering the straw mat without turning on the fan during snowy and rainy day.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of the rapid infiltration bed of sunlight greenhouse for improving matrix temperature.
