A pretreatment systems is reinforceed to drain for water body remediation

The utility model discloses a pretreatment systems is reinforceed to drain for water body remediation, the system includes the ecological ecological substrate who floats bed, elastic filler bed and hang down of arc, the ecological bed that floats of arc sets up in the drain outside, the elastic filler bed is located the ecological inboard arc that floats the bed of arc and is enclosed the frame inboard. Two -layer inside and outside ecological substrate that elastic filler bed below hung divides, in the aspect by outer in and with the contact of the oxygen attitude formula that tapers off. Theutility model discloses the plant roots and the elastic filler bed of ecological superficial bed cultivation hang the microbial film and the water ecosystem constitution of growing and reinforce pretreatment systems on the carrier, biofilm carrier through floating bed plant root system and the filler surface growth that hangs, can come the organic matter suspended solid of aquatic to hold back the drain, and the water tr
