When in use, PVC / PPH plastic particles, biological organic matter with uniform particle size (rice husk, bark, bamboo fiber, sawdust, etc.) and inorganic porous filler with uniform particle size (activated carbon, zeolite, ceramsite, calcium carbonate, etc.) are respectively placed in the inner cavity of the hopper body (105), and the PVC / PPH plastic particles are uniformly added into the interior of the heated conveyor mixer (2) at a mass ratio of 30% to 50%, the biological organic matter with uniform particle size (rice husk, bark, bamboo fiber, sawdust, etc.) is uniformly added into the interior of the heated conveyor mixer (2) at a mass ratio of 5% to 30%, and the inorganic porous filler with uniform particle size (activated carbon, zeolite, ceramsite, calcium carbonate, etc.) is uniformly added into the interior of the heated conveyor mixer (2) at a mass ratio of 10% to 50%, wherein the inorganic materials are activated carbon and zeolite, wherein the fruit shell activated carbon accounts for 15% to 20% and the zeolite accounts for 25% to 30%; S3, further in a heated conveyor mixer (2), the PVC / PPH plastic particles, the bio-organic matter and the inorganic porous filler are stirred and mixed uniformly and heated to soften the plastic to form a melt, and then the melt is processed into a ball ring, a Raschig ring or other filler shape by injection molding with an embossing mold (6) under the action of an extruder (5), and after cooling and hardening, the melt is demolded to form a primary product, and the wall thickness of the ball ring, Raschig ring or other molded product is controlled to be 1.1-2.6 mm, which is consistent with the conventional size on the market, and the processed ball ring, Raschig ring or other primary products are further placed in a sandblasting machine (7) for internal and external surface grinding; S4, exposing the biological organic matter and inorganic porous filler covered or wrapped by the plastic, increasing the filler specific surface area and microbial contact surface, and at the same time increasing the filler's affinity with water and exhaust gas, the polished product enters the inner cavity of the collection box (91), and is protected by the positioning plate (92), the damper (94) and the first spring (93) to prevent it from falling and breaking; S5, mainly controlling the metering of the discharge by setting a quantitative valve (108), storing the material particles by setting a hopper body (105), stirring the material particles by setting a stirring frame (106) to prevent the material particles from being blocked during the discharge, driving the stirring frame (106) by setting a third motor (11), shaking the hopper body (105) by setting a vibration motor (107) to prevent the material particles from being blocked during the discharge, limiting the top cover (102) by setting a limiting slide bar (103) to prevent the top cover (102) from shaking during the movement, blocking the top of the hopper body (105) by setting the top cover (102), and limiting the top of the top cover (102) by setting a second spring (104); S6. By providing a fixing rod (109), it is convenient to connect and fix the heated conveying mixer (2) and the U-shaped seat (110); by providing the U-shaped seat (110), the positioning rod (112) is fixed; by providing a limiting plate (113), the hopper body (105) is limited to prevent the hopper body (105) from shaking during the movement; by providing a third spring (111), the limiting plate (113) is buffered; by providing a positioning plate (92), the product is mainly protected to prevent it from falling directly into the inner cavity of the collection box (91); by providing a damper (94), the positioning plate (92) is buffered and damped, and in cooperation with the first spring (93), the stability of the positioning plate (92) during movement is improved.
