Embodiment
As accompanying drawing 1, shown in 2 and 3, a kind of improved structure of deflector type internal recycle biofilm reactor, it comprises reactor body 1, it is characterized in that: described reactor body 1 is separated plate 2 and is divided into upper and lower two portions, top is divided into the current turbulent flows district 101 of horizontal flow direction, bottom is divided into bio-reaction zone 102, described bio-reaction zone 102 is divided into water stream channel 4 by least two vertical small baffles 3, small baffle 3 one end are arranged on division plate 2 or reactor body 1 inwall, 2 of the other end and reactor body 1 or division plates are spaced a distance, current from left to right flow at reactor internal recycle according to vertical folding stream mode in water stream channel 4, 3 of described small baffles are equipped with ceramic honey comb 5 as biofilm carrier, bottom between two small baffles 3 at current in the flow state that makes progress is provided with solarization air cap 6, reactor body 1 is connected with water circulating pump 7, water circulating pump 7 water outlets pass into the current turbulent flows district 101 of horizontal flow direction, water circulating pump 7 water-ins are connected to bio-reaction zone 102 and between small baffle 3 and reactor body 1 inwall, water circulating pump 7 water-in pipelines are provided with hole or hole 701, this hole or hole 701 are a vesicular structure, the pipeline of this vesicular structure is set with guard 8 outward, guard 8 can avoid water circulating pump 7 to stop up,
Described solarization air cap 6 can be by regulating the size of its aeration rate to promote current at the dissolved oxygen content of the turbulent flows of biofilm surface or control different zones.
The water-in 103 of described reactor body 1 is located on reactor body 1 wall of bio-reaction zone 102.
