The technical problems to be solved in the utility model is achieved through the following technical solutions.The utility model is a kind of pulsed granular sludge bed reactor, its feature is: the reaction tower comprising tubular, triphase separator is provided with in described reaction tower, in funnel-form bottom described reaction tower, forming reactions room, space between bottom described triphase separator and reaction tower, water inlet pipe is provided with bottom described reaction tower, described water inlet pipe is connected with wastewater inlet pipe and backwater water inlet pipe, the lower end of described backwater water inlet pipe is connected with water inlet pipe, the described upper end of backwater water inlet pipe is connected with the top of reaction chamber, described wastewater inlet pipe and backwater water inlet pipe are equipped with stream of pulses generating unit, described stream of pulses generating unit comprises surge generator, the liquid pulse jet pump be connected with surge generator.
In a kind of pulsed granular sludge bed reactor of the utility model technical scheme, preferred technical scheme feature is further: described water inlet pipe comprises left water inlet pipe and right water inlet pipe, described left water inlet pipe is connected with described wastewater inlet pipe, and described right water inlet pipe is connected with described backwater water inlet pipe.
In a kind of pulsed granular sludge bed reactor of the utility model technical scheme, preferred technical scheme feature is further: described left water inlet pipe is connected with bottom reaction tower respectively by some distributive pipes with right water inlet pipe, described distributive pipe is equipped with magnetic valve, described magnetic valve is connected with PLC, and described PLC is connected with described surge generator.
In a kind of pulsed granular sludge bed reactor of the utility model technical scheme, preferred technical scheme feature is further: connected by the pipe connecting of band valve body between described left water inlet pipe and right water inlet pipe.
Compared with prior art, the utility model has following technique effect:
(1) by arranging stream of pulses generating unit on wastewater inlet pipe and backwater water inlet pipe, granular sludge bed reactor is made to produce uneven distribution over time and space at influent waste water and backwater circulation, larger pulse flow is produced in short period of time or local space, hydraulic mixing effect can be improved, strengthen sludge circulation, prevent current dead angle and the susceptible to plugging problem of water distribution mouth, improve the reaction effect of reactor;
(2) the utility model structure is simple, easy to operate;
(3) by arranging the distributive pipe of many provided with electromagnetic valves, can be that water inlet and backwater circulation are arranging different distribution points by PLC, distribute by the regular cycles of setting, larger local pulse can be produced like this at each point, reactor bottom can be made without dead angle, more can reduce the blocking of pipeline, improve the reaction effect of reactor further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is embodiment 2 structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction of its power.
Embodiment 1, with reference to Fig. 1, a kind of pulsed granular sludge bed reactor, comprise the reaction tower 1 of tubular, triphase separator 4 is provided with in described reaction tower 1, forming reactions room, space 10 bottom described triphase separator 4 and reaction tower between 11, bottom described reaction tower, 11 are provided with water inlet pipe 4, described water inlet pipe 4 is connected with wastewater inlet pipe 2 and backwater water inlet pipe 3, the lower end of described backwater water inlet pipe 3 is connected with water inlet pipe 4, the upper end of described backwater water inlet pipe 3 is connected with the top of reaction chamber 10, described wastewater inlet pipe 2 and backwater water inlet pipe 3 arrange water inlet pulse generating unit 21 and recirculated water pulse generating unit 31 respectively, described water inlet pulse generating unit and recirculated water pulse generating unit include surge generator, the liquid pulse jet pump be connected with surge generator.The pulse of surge generator can be arbitrary form, and need to set different Changing Patterns according to technique, can be consecutive variations from small to large or from big to small, also can be non-consecutive variations, can be that the jumping characteristic from certain value to another value changes.
Embodiment 2, with reference to Fig. 2, on the basis of embodiment 1, water inlet pipe is arranged to left water inlet pipe 41 and right water inlet pipe 42, described left water inlet pipe 41 is connected with described wastewater inlet pipe 2, and described right water inlet pipe 42 is connected with described backwater water inlet pipe 3.
