Experimental Research On FILTER System

This paper is intended to explicate the system of FILTER (Filtration and Irrigated cropping for Land Treatment and Effluent Reuse) by experiment, on the basis of traditional land dispose concerning sewage. FILTER system can use nutritious sewage to irrigate crop, at the same time, it can dispose a large amount sewage with a smaller land, and it can also designed to recollect drainage water for irrigation or other uses through sewage device that is fixed and controlled in the FILTER system. By the reasonable design of the load of sewage device and the rate of drainage, the decontamination rate of filter can be guaranteed and the discharged sewage could reach the requirement of environment department .The contamination in the soil could be absorbed by the plant in FILTER system, then the continuable homeostasis will set up in the system. FILTER system not only dispose the sewage, but also make the output of crop keep steady increasing, thus the charge of construction and operation of the system will be compensated.The experiment show that by using this system, not only sewage resource is made full use, but also the contaminant in the sewage is effectively removed. This technique can be applied in the area of sewage irrigation, sewage disposal and sewage recycle. So it will be excellent and perspective technology involving sewage disposal.
