NOVELTY - Artificial wetland of farm sewage and rain water are disposed and comprehensively utilized by processing collected rain water in pipe-shaped sand sediment tank and farm sewage into pipe-shaped sand sediment trap; subjecting farm sewage to filtering, absorbing, oxidizing, microorganism discomposing and plant absorbing in vertical artificial wetland plant bed; flowing farm sewage into the reservoir of organism; and further purifying farm sewage and rain water through aerobiotic, facultative, anaerobic microorganism.    USE - Method for disposing and comprehensively utilizing artificial wetland of farm sewage and rain water. The farm sewage includes domestic sewage comprising water for bathing, water for washing vegetables, water for washing clothes and water for washing bowls, except the human and animal waste matter. The rain water comprises roofing water and terrace water collected in the village homes (all claimed).    ADVANTAGE - The method combines the farm sewage disposal and water rain disposal and reserves and recycles them; utilizes the advanced pipe-shaped sand sediment trap, vertical artificial wetland plant bed, vertical gravitationally flowing aerator and the reservoir of organism; achieves the requirement of purification; and has less amount of electricity consumption.    DETAILED DESCRIPTION - Disposal and comprehensive utilization of artificial wetland of farm sewage and rain water comprises collecting the farm sewage and rain water; processing the rain water in pipe-shaped sand sediment tank and transferring the farm sewage into pipe-shaped sand sediment trap; transferring the rain water into a reservoir of organism and transferring the farm sewage into a vertical artificial wetland plant bed; performing filtering, absorbing, oxidizing, microorganism discomposing and plant absorbing in the vertical artificial wetland plant bed, and flowing the processed sewage into vertical gravitationally flowing aerator; flowing farm sewage into the reservoir of organism; and further purifying farm sewage and rain water through aerobiotic, facultative, anaerobic microorganism. When the water in the reservoir of organism overflows, it flows into the farm irrigating water system through outlet well and is used as in farm irrigation.
