Principle of work:
The urea industry factory effluent enters frame trough 2 from water inlet pipe 1, flow through mechanical grille 3, the bulk of damming suspended substance, in order to avoid obstruction follow-up equipment, cross grid water and flow into equalizing tank 4 regulating pondages, homogenizing water quality, guarantee the follow-up equipment load evenly, lift pump 10 is pressed the operation of SBR water inlet cycle request, equalizing tank water is sent into sbr reactor device 12, and the sbr reactor device is through water inlet, aeration, precipitation, strain water and operation such as idle is finished a processing cycle successively, enter monitoring pond 35 by the treating water that hydrophone discharges of straining in the sbr reactor device 12, on-line monitoring instrument 38 such as COD are joined by institute in the monitoring pond, under its monitoring, the qualified water discharging, and finish whole water treatment technological process.
Nutrition source replenishes and stirs; Because biochemical processing process requires C/N 〉=3 that biochemical condition preferably o'clock is just arranged, and the ratio of C and N does not often reach requirement in the Ammonia Production waste water, so must add the strong carbon source of biochemical to equalizing tank in good time, carbon source is added in the equalizing tank 4 through hydrocone type measuring apparatus 6 by carbon source jar 7.In equalizing tank 4, be provided with diving mixer 47 and stir in good time, and guarantee that mud does not sink to the bottom and plays suitable biochemistry and gives reactivity.
Air feed system: when sbr reactor device 12 needed air feed, wind regime was sent into sbr reactor device 12 interior air-distributing devices 16 by high pressure positive blower 14 and is carried out aeration.
Outlet system: when sbr reactor device 12 arrives drainage procedure, strain water, supernatant liquor is sent into monitoring pond 35, when 38 monitorings of on-line monitoring instrument are qualified, discharge from water discharge spout 34 up to standard by straining hydrophone 13 execution.
Spoil disposal: when sbr reactor device 12 needs spoil disposal, open electric control valve 20, the mud in the sbr reactor device 12 is collected to enter in the sludge thickener 22 through sludge drainage system 17 and is concentrated.
The accident safeguards system; Accident waste water generally has following three classes: 1) first rainwater, fire-fighting accident water and equipment breakdown or maintenance waste water, these waste water complicated components, concentration height, flow into frame trough 40 by accident wastewater inlet pipe 39, after mechanical grille 41 blocks the bulk suspended substance, flow into accident pool 42, send into equalizing tank 4 through accident pump 43 by the acceptable meteor of water purifying plant again and participate in handling.For homogenizing water quality prevents precipitation, diving mixer 47 is housed in the accident pool 42.2) the disproportionate waste water of urea: NH in equalizing tank
3When-N does not become biochemical ratio with COD, promote, send into accident pool 42 through surmounting valve 45 and surmounting pipe 46 with lift pump 10.3) the defective water of sbr reactor device: when occurring not water up to standard in the monitoring pond 35, send equalizing tank 4 back to or accident pool 42 participates in processing again with monitoring pump 36.
Sludge treating system: after mud concentrates in sludge thickener 22, supernatant liquor flows back to equalizing tank 4, mud promotes with mud lift pump 24, send in the pressure type sewage sludge reactor 26 and add the coagulant aids reaction that case 31, coagulant aids volume pump 30 are sent here from coagulant aids, reaction mud is pressed into sludge drying equipment 28, dried mud transports, and equalizing tank 4 is sent in water outlet back to.
Automatically control: the automatic control of sbr reactor device: the sbr reactor device is the interval type biochemical processing process, and its reaction can be divided into into water, aeration, precipitate, strain water finished with idle five stages, and its operation is mainly controlled automatically with PLC by various instrument monitorings and finished.
Fill phase; After it's the idle stage has been past sbr reactor device 12, enter the next processing cycle, then instruct lift pump 10 to last to 12 water inlets of sbr reactor device, to the time pump trip by water inlet.
Aeration phase: instruction frequency conversion high pressure positive blower 14 lasts air feed by aeration after water inlet; shut down to the time; its wind supply quantity instructs fan frequency conversion by control instruments DO on-line monitoring instrument test oxygen in water; adjust wind supply quantity; other has ORP on-line monitoring instrument to judge the redox ability of aerobic stage; be the processing power of SBR, adjust aeration period with this.
Precipitate phase: this stage is not opened any equipment, lasts by precipitation and carries out.
Bleeding stage: after precipitation finished, instruction was strained hydrophone 13 and is lasted to carry out by draining and strain water, strained hydrophone and can adopt product commonly used at present, and drain discharge and draining last but must regulate automatically.
The idle stage: last by idle, open the diving mixer 47 that is installed in the sbr reactor device 12 automatically, carry out anoxic, anaerobic reaction, after finishing fully in the idle stage, equipment enters the circulation of lower whorl treatment process.
Spoil disposal: MLSS on-line monitoring instrument is housed in the sbr reactor device 12, sludge concentration in the monitoring reaction device, when MLSS＞8000mg/L, mud valve 20 spoil disposals are opened in instruction automatically.Sludge volume MLSS index monitoring is in accordance with regulations determined.
Monitoring pond automatic control: the water outlet of sbr reactor device 12 enters monitoring pond 35, NH in the pond
3When-N and COD on-line monitoring instrument monitoring pool water were defective, instruction monitoring pump 36 was opened automatically, defective water was returned equalizing tank 4 or accident pool 42 participates in handling again, in guarding pump 36, come the hydration lattice till.
Equalizing tank water quality control: PH, COD, NH are housed in the equalizing tank 4
3On-line monitoring such as-N and liquid level sensor instrument 48, come every water quality in the monitoring pool, when pond water monitoring index does not meet SBR12 and handles index, the instruction water outlet electrically-controlled valve 9 that switches off the pump then, open lift pump 10 and surmount valve 45, it is pending that this water is sent into accident pool 42.
Other system: other system as carbon source add, mechanical grille, diving mixer, accident pump, sterilization and the sludge treating system automatic program all can adopting.
