The top of described triphase separator is provided with effluent weir, and the side of described effluent weir is provided with water leg, on described reactor body, is provided with rising pipe by described water leg.
The top of described triphase separator is provided with settling region, and the top of described settling region is provided with skimming plate.
Described skimming plate is downward-sloping spirrillum.
The bottom of described reactor body is provided with slag-drip opening.
Described reactor body is provided with manhole and some thief holes.
The triphase separator of some even circumferentials arrangement is provided with in described three-phase separation area.
Angle bottom described water distributing pipe and described reactor body is 30 ~ 45 °.
The beneficial effects of the utility model are: 1) three phase separation is effective: establish separate chamber and collection chamber in triphase separator, sewage is after separate chamber's three phase separation, gas is discharged through venting port after entering collection chamber, water overflows through effluent weir after skimming plate pushing off the slag, and solid is then settled down to reactor bottom by self gravitation effect; 2) processing efficiency is high: be provided with diving mixer in the mud section of reactor, regularly stir mud, in case the heavy collection of mud, sewage is fully contacted with Sludge Bed, fast reaction speed, improves processing efficiency.

Embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated.
Fig. 1 is an embodiment of the present utility model, comprise reactor body and water inlet system, described reactor body inside is provided with reaction zone and three-phase separation area from top to bottom successively, is provided with Sludge Bed in described reaction zone, is provided with triphase separator in described three-phase separation area;
The arrangement that described water inlet system comprises the surge generator 1 being located at described reactor body top, the vertical tube 2 being located at described reactor body inside and is located at the water distributing pipe 3(water distributing pipe 3 bottom described reactor body as shown in Figure 2), described water distributing pipe 3 is 30 ~ 45 ° with the angle bottom described reactor body, increase the collision of water and reactor body, strengthen flow velocity; Described surge generator 1 is provided with water inlet pipe 101.
Also comprise diving mixer 4, described diving mixer 4 to be positioned at above water distributing pipe 3 and to be positioned at below Sludge Bed.
Separate chamber 5 and collection chamber (in Fig. 1 collection chamber 1 and collection chamber 2 602) is provided with in described triphase separator, the top of described separate chamber 5 comprises the gas skirt 502 that back up pad 501 and cross section are inverted-V-shaped, the bottom of described collection chamber is provided with reflector, and the top of described collection chamber is provided with vapor pipe (in Fig. 1 vapor pipe 1 and vapor pipe 2 702).
The top of described triphase separator is provided with effluent weir 8, and the side of described effluent weir 8 is provided with water leg 801, on described reactor body, is provided with rising pipe 802 by described water leg 801.
The top of described triphase separator is provided with settling region, and the top of described settling region is provided with skimming plate 9.Described skimming plate 9 is downward-sloping spirrillum.
The bottom of described reactor body is provided with slag-drip opening 10.
