Embodiment Construction
[0039] The present invention is as attached figure 1 The device diagram shown is implemented.
[0040] The raw water tank 1 has a volume of 120L, and is connected to the water inlet pump 2, the water inlet flowmeter 3 and the water inlet valve 4 in sequence along the water inlet direction through pipelines. The water inlet valve 4 is located on the upper part of the water inlet side of the main body 5 of the device. The main body of the device 5 is divided into 4 areas through the partition plate. The effective water volume of the main body 5 of the device is 80L, which is divided into 4 areas. The anaerobic area A is in sequence along the water flow direction. (10L), anoxic zone B (20L), aerobic zone C (40L), precipitation zone D (10L). The suspended filler 8 filled in the aerobic zone C is a hollow ring with a filling rate of 30%, made of polyethylene, with a diameter of 20mm and a density of 0.96g / cm 3 , The porosity is 96%.
[0041] A pusher 6 is set in the anaerobic zo...
