NOVELTY - Physical process and artificial wetland combined processing system, comprises a physical processing device and an artificial wetland processing device, both of which combine to form a sewage water processing system. The water inlet of the sewage of the residential area is arranged in front of the physical processing device and the water outlet of the physical processing device is connected with the artificial wetland processing device. The physical process mainly to carry out the pre-process and the artificial wetland mainly to carry out the precise process to reach the standard.    USE - The process is useful for sewage treatment.    ADVANTAGE - The process: has combined technology of the physical process and artificial wetland processing system; reduces the operating cost of the physical treatment; has high stability for the treatment efficiency of the sewage pollutants of the residential area; has small influence on the water quality; has simple equipment and low operating cost and; is practical and feasible technology for the treatment and recycling of the sewage in the residential area.    DETAILED DESCRIPTION - Physical process and artificial wetland combined processing system, comprises a physical processing device and an artificial wetland processing device, both of which combine to form a sewage water processing system. The water inlet of the sewage of the residential area is arranged in front of the physical processing device and the water outlet of the physical processing device is connected with the artificial wetland processing device. The physical process mainly to carry out the pre-process and the artificial wetland mainly to carry out the precise process to reach the landscape water utilization standard GB/T18921-2002. The physical process, the artificial wetland physical ecological control and optimization combination is carried by adjusting the physical process and completely carrying out the artificial wetland processing capability. The physical processing device is a concrete deposition device and comprises a drug adding unit, a fast mixing unit, a mechanical flocculation unit and a deposition unit connected with each other by pipelines. The artificial wetland is the lateral underflow wetland bed, which comprises a lateral underflow bed and a natural reoxygenation region with multiple stages of downwards gradients, where each lateral underflow wetland bed is internally provided with parallel and crossed separating plates. The space in the bed is divided into s-shaped water flow channels and the channel is internally filled with macadam or ceramic particle fillers, where the filler is 0.45-0.65 m thick and the aquatic plant is planted in it. The work condition matching relationship of the system comprises the hydraulic retention time and powdered activated carbon are respectively equal to 3-3 minutes and 22-26 mg/l, the stirring speed of 100-140 revolutions/minute, and the hydraulic retention time and polyacrylamide of mechanical flocculation unit are respectively 3-5 minutes and 0.07-0.08 mg/l, the stirring speed of 25-35 revolutions/minute. The work condition of the artificial wetland includes a temperature in summer, which is not less than 15 degrees C, the water outlet is satisfied with the urban sewage regeneration and reutilization urban non-drinking water quality GB/t18920-2002 and urban sewage regeneration and reutilization landscape environment water quality GB/T18921-2002. The best load of the artificial wetland is 20.5-21.5 cm/d. The temperature in winter is less than 15 degrees C, the water force load of the artificial wetland is 9.5-11.5 cm/d and the water outlet is satisfied with the standards.
