Study On Garden Water Treatment With Subsurface Infiltration System

Based on the theory of natural ecology, it is a wastewater purified technologywhich is favorable feasibility and developmental foreground in China. As a result of thetraditional subsurface infiltration system has some defects, such as, hydraulic loading islow, using ground-area is large, field condition is strict, climate affect and so on, theapplication of subsurface infiltration system is limited. This paper introduced subsurfaceinfiltration system is a false intensified treatment technology on wastewater ecologicalengineering, Wastewater applied manipulative in soil with some structure, some depthbelowground, and favorable diffusion. Wastewater flew into round under soil soakagecapillary and infiltration. Under synthesize purify by Soil-Microorganism-Plant system,subsurface infiltration system is a land treatment system that wastewater is treated withused need. It conquered some defects of traditional subsurface infiltration system, and itpossessed some advantage, such as, build charge is low, run cost is low, operate is simple,purify is high, drainage quality is well, recycle using, and no bring peculiar smell, noaffect surface sight, effect is little by outsight, and synthesis effect gained improve in abig way. Aim at the characteristic of new subsurface infiltration system, it is investigatedby test in theory and in practice. Main research work has been listed as follows:(1) In theory, some action mechanism has been discussed detailed refer tosubsurface infiltration system, so that it could increase its feasibility probability.(2) In practice, prophase experiments have been carded out with wastewater ofriverway in Suzhou University of Science and Technology. Consequently, it filtrateoptimum subsurface infiltration system it could deal with garden water in the HumbleAdministrator's Garden. This proved new subsurface infiltration system is feasibility.(3) Performance testing on garden water treatment with subsurface infiltrationsystem in the Humble Administrator's Garden has been carried out. Some pollute indexes,such as, Turbidity, COD_Mn, Nitrogen, Phosphorus, and so on, have been analyzed so thatit could display superiority of its performance.(4) The work status in the Humble Administrator's Garden is carried out toinvestigate subsurface infiltration systems, the work effect is analyzed, and it has used inimprove of garden water quality, it is a new attempt. This is very important significancein popularization of subsurface infiltration systems.
