Description
Technical field
The present invention relates to a kind of vertical anaerobic process tank integrated triphase separator, belong to technical field of sewage.
Background technology
In the anaerobic biological treatment process, can produce CH
4, CO
2, NH
3Deng gaseous matter, the micro-bubble that they form can adhere to a large amount of anaerobism cenobiums and rise with current.How to control the loss of anaerobism cenobium, gas-solid liquid triphase separator is designed to key.Getting well with bad of three phase separation effect directly has influence on the anaerobic treatment effect.Triphase separator structure formation is varied at present: the triphase separator that assembly unit is at the construction field (site) arranged; Have in factory and produce, triphase separator module that construction and installation are more convenient or the like.But their structure and anaerobic device body can not form an organic whole, because reasons in structure, what have can not collect the foul smell that produces in the anaerobic treatment fully, what have can not effectively control zoogleic loss, separate the solid that sinks and be back to the anaerobic reaction district, its amount is to regulate with operation condition, and capacity of resisting impact load is poor.
As shown in Figure 1, be the three-phase separating device structural representation in a kind of existing anaerobic treatment technology, described three-phase separating device comprises anaerobic process tank 22, anaerobic process tank 22 tops are provided with venting port 30, anaerobic process tank 22 upper inside are provided with collection chamber 29, collection chamber 29 belows are reaction zone 27, reaction zone 27 bottoms are provided with water inlet pipe 26, anaerobic process tank 22 bottoms are provided with mud discharging mouth 25, and wherein, anaerobic process tank 22 crown centers are provided with triphase separator 21, triphase separator 21 center of top are provided with water leg 20, water leg 20 connects rising pipe 23, and triphase separator 21 inside are settling region 28, and triphase separator 21 bottoms are provided with reflector 24.It is up that waste water enters anaerobic process tank 22 backs from water inlet pipe 26, after handling by reaction zone 27, carries out gas delivery through reflector 24, and the gas after the separation enters collection chamber 29, is discharged by venting port 30 at last; Mud after the separation and the aqueous solution then slit by 21 of reflector 24 and triphase separators enter settling region 28 and carry out solid, liquid and separate, the supernatant liquor overflow is to water leg 20, discharge from rising pipe 23, the isolated mud slit by 21 of reflector 24 and triphase separators once more enters reaction zone 27 and carries out wastewater treatment.The mud that is deposited in anaerobic process tank 22 bottoms regularly effluxes from mud discharging mouth 25.The shortcoming of said apparatus is: 1. the gas in gas, mud, the water mixed liquid can enter the settling region, be that mud and water are before entering the settling region, gas is not effectively separated removal, disturbed the separating effect of mud and water to the settling region owing to gas leakage, make the water outlet muddiness, suspension content is higher, and anerobe is also run off thereupon; 2. at the place, slit of 21 of reflector 24 and triphase separators, the mud and the aqueous solution of rising is arranged, the mud of decline is also arranged, the two forms convection current, thereby has influenced the separating effect of mud, causes the water outlet muddiness, is unfavorable for follow-up unitary operation; When 3. the mud of separation sinking returned reaction zone, its amount can not be regulated with the variation of operation condition, and to keep sludge concentration certain in the anaerobic process tank and long sludge age, capacity of resisting impact load is poor.
Summary of the invention
The purpose of this invention is to provide the incorporate waste disposal plant of a kind of anaerobic device and triphase separator.
In order to achieve the above object, technical scheme of the present invention provides a kind of vertical anaerobic process tank integrated triphase separator, comprise the vertical type anaerobic jar, the top of vertical type anaerobic jar is provided with venting port, the upper inside of vertical type anaerobic jar is provided with collection chamber, the bottom of vertical type anaerobic jar is provided with water inlet pipe, it is characterized in that, the middle part, below of collection chamber is provided with settling tank, the settling tank internal upper part is provided with water leg, and the bottom of water leg connects rising pipe, and the bottom of settling tank connects bucket, the bottom of bucket connects shore pipe, the middle part of settling tank is provided with verticle reinforced gas-liquid separation device, and an end of verticle reinforced gas-liquid separation device connects collection chamber, and the other end connects bucket, thrust-augmenting nozzle one end is located in the verticle reinforced gas-liquid separation device, and the other end is located between settling tank outer side wall and the vertical type anaerobic jar inner side-wall.
Further, be positioned at the position of strengthening the gas-liquid separation device below in the bucket and be provided with reflector.
