Embodiment
Using aeration tank foul waste gas circulating purification system and its technique in sewage disposal of the present invention, the foul gas that aeration tank in certain dyeing Sewage Disposal is produced is handled, foul gas main component is：Hydrogen sulfide, methyl mercaptan, methyl sulfide and ammonia.Aeration tank specification is：Length × width × height=20m × 5m × 4.5m, HRT=2h, processing water 500m3/d。
Wherein, aeration tank seal closure is glass steel material, and piping material is 304 stainless steel tubes, and circulating fan is 25000m from air quantity3/ h centrifugal blower, air exhauster selects 20000m3/ h axial flow blowers, temperature sensor A and temperature sensor B use thermocouple, and on the gas piping at the forward and backward two ends of finned heat exchanger.Pressure sensor is using pressure transmitter and on the seal closure of aeration tank.
The foul gas that aeration tank is produced during processing sewage, forms confined space, with extraneous relative insulation after aeration tank seal closure is installed additional.By gas piping after foul gas generation, thermocouple A, finned heat exchanger, thermocouple B are sequentially passed through.Obtained initial temperature t is detected by thermocouple A0Compared with design temperature scope, control heat exchanger is started working, ensure temperature t after the balance that thermocouple B detections are obtained1In allowed band.When such as summer design temperature scope is 30 ~ 40 DEG C, thermocouple A detects obtained temperature t in real time0When reaching 40 DEG C, finned heat exchanger starts refrigeration, ensures the temperature t that thermocouple B detections are obtained1In the range of 30 ~ 40 DEG C, will finally temperature t after balance be reached1Foul gas will be passed through supplement aerating pipelines gas piping.
Foul gas after overregulating, in the gas pipeline for being passed through supplement aeration unit, constantly worked via circulating fan, foul gas passes through pipeline, in the porous tubular aerator for reaching the distribution of aeration tank bottom, it is aerated by the hole of opening in porous tubular aerator into water.Simultaneously, dissolve dissolved oxygen content in oxygen detection monitoring aeration tank, when dissolved oxygen content is less than 1.5mg/L, the valve opening of flow control valve is controlled, opening degree is 50%, and fresh air is supplemented from external environment, now, foul gas and fresh air composition mixed gas, using mixed gas as the gas source of aeration, reach the agitation to aeration tank and the purpose of aeration.When dissolved oxygen content is more than 3.0mg/L in dissolving oxygen detection detection aeration tank, then the valve of flow control valve is closed, fresh air is not supplemented now.
After constantly circulation, concentration of the foul gas in the seal closure of aeration tank will be lifted constantly, and sealed internal mask pressure and constantly raised.When pressure transmitter gauge pressure shows that the pressure in the seal closure of aeration tank reaches 500Pa, control relief valve, foul gas terminal processing device and air exhauster will start simultaneously.Now, the foul gas of high concentration will be entered by pipeline and handled in low-temperature plasma photocatalysis integrated apparatus.Pass through floss hole qualified discharge after the treatment.When the pressure that pressure sensor feeds back is less than 0Pa, then controls relief valve, foul gas terminal processing device and air exhauster to simultaneously close off, only carry out foul gas circulation.
After foul gas circular treatment in aeration tank in sewage disposal, foul gas discharge capacity greatly reduces, while foul gas terminal processing device operating cost is substantially reduced, implementation result is obvious.
