(3) dephosphorization is needed to denitrogenate, treatment tank carries out releasing phosphorus, after reaching the design anaerobism time, start gas blower, and start submersible high-efficiency energy-saving stirring aerator, turn off the blast after reaching anoxic requirement machine, keep submersible high-efficiency energy-saving to stir aerator operation to stir, after reaching design hypoxic exposure, denitrification process completes, and then starts gas blower oxygen supply, keeps submersible high-efficiency energy-saving to stir aerator and runs, carry out nitration treatment, its cycle of operation is depended on and releases phosphorus, denitrification and nitrated design time.
Embodiment 2
Denitrification postpositive disposal operation scheme, according to the design and operation mode that is divided three classes the need of denitrogenation dephosphorizing:
(1) dephosphorization is not needed, but need denitrogenation, when the water level in treatment tank reaches design water level, start submersible high-efficiency energy-saving stirring aerator to stir, after reaching design hypoxic exposure, denitrification process completes, and starts gas blower oxygen supply, carry out nitration treatment, its cycle of operation depends on the design time of nitrification and denitrification;
(2) do not need dephosphorization and denitrogenation, when the water level in treatment tank reaches design water level, start gas blower oxygen supply, and start submersible high-efficiency energy-saving stirring aerator, carry out Wastewater Treated by Activated Sludge Process continuously;
(3) dephosphorization is needed to denitrogenate, treatment tank carries out releasing phosphorus, after reaching the design anaerobism time, start gas blower, and start submersible high-efficiency energy-saving stirring aerator, turn off the blast after reaching anoxic requirement machine, keep submersible high-efficiency energy-saving to stir aerator operation to stir, after reaching design hypoxic exposure, denitrification process completes, and then starts gas blower oxygen supply, keeps submersible high-efficiency energy-saving to stir aerator and runs, carry out nitration treatment, its cycle of operation is depended on and releases phosphorus, denitrification and nitrated design time.
The difference of above-mentioned two macrospecies operation scheme is that denitrification is preposition or denitrification is rearmounted, and it arranges the content that order depends on ammonia nitrogen and total nitrogen in former water.In addition, the equipment that system cloud gray model whole process relates to only has gas blower and submersible high-efficiency energy-saving to stir aerator, can realize fully automatic operation by PLC automatic control.
The investment of this operation scheme is equally divided into technique structures, processing unit, process control system and supporting illumination section with traditional technology.Technique structures: due to this technique novel design structurally and equipment high efficiency, floor space is less, and according to the analog calculation of the various water yield, floor space is the 50-75% of traditional technology.In addition, the operation content due to this technique completes in a pond, do not have function division, so subregion partition wall reduces in a large number.Processing unit: the equipment arranged due to technique is only gas blower and submersible high-efficiency energy-saving stirring aerator, and technique oxygen requirement is lower, more traditional Equipments Setting (gas blower, aerating system, diving mixer, Digestive system reflux pump, settling tank equipment or water decanter etc.) reduces in a large number.Process control system: due to device category and comparatively small amt, electrical cable also reduces thereupon.
Working cost comprises the electricity charge, labor wage, upkeep cost.The electricity charge: this process operation expense mainly electricity charge, and electrical equipment has gas blower and submersible high-efficiency energy-saving to stir aerator.Labor wage: level of automation is high, personnel depaly requires few.Maintenance and repair takes: equipment performance is reliable, and work-ing life is longer, affects less by other external environments, and therefore maintaining number of times is less; And without the need to sewage emptying and more maintenance tool and utility appliance during maintenance, therefore maintenance cycle is short, maintenance cost is low.
More than show and describe ultimate principle of the present utility model; principal character and advantage; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
