Description
Technical field
The utility model relates to a kind of sewage-treatment plant, in particular to a kind of low energy consumption constant flow is discharged MBR device.
Background technique
In recent years, MBR (membrane bioreactor) technique is due to having many advantages, such as that effluent quality is good, and occupied area is small, extensively
The general sewage treatment project applied to numerous different scales.Especially in villages and small towns sewage treatment field, MBR complexes are due to tool
There are the advantages such as occupied area is small, and high degree of automation, effluent quality is good, and construction and installation are quick, it is standby to be received by the market.But it is existing
There is the outlet system of MBR technology and device to generally use suction pump power frequency operation, power frequency operation water outlet suction pump can make MBR film exist
The far super design discharge of initial operating stage water yield, this is because MBR film has just brought into operation, stage pollution is lighter, and system resistance is smaller,
Water outlet suction pump actual condition point is much biased to the right side of pump capacity curve, and the practical effluent flux of film is far super to design flux, such as
This will cause fouling membrane and accelerates to aggravate, meanwhile, it will also result in water pump current overload, pump motor can be burnt up when serious, to avoid
Such consequence, can only will be discharged pump valve and turn down and increase system resistance in system initial operating stage, to control water yield, still
Such mode brings very big inconvenience to operation operation, and is unfavorable for energy conservation, causes very big waste.
Summary of the invention
This it is practical it is new be designed to provide a kind of low energy consumption constant flow water outlet MBR device, the device is in existing MBR skill
On the basis of art, increases water outlet electromagnetic flowmeter, frequency converter and PLC control system after MBR water outlet pump, water flow meter is believed
Number line is connect with PLC, and PLC is connect with frequency converter, and frequency converter is connect with water outlet pump, when MBR water flow is more than design discharge,
PLC is issued to frequency converter and is instructed, Frequency Converter Control water outlet pump low-frequency operation, when MBR water flow is lower than design discharge, PLC
It issues and instructs to frequency converter, the operation of Frequency Converter Control water outlet pump high frequency remains that MBR device is measured according to design discharge constant current
Water effectively reduces the operation energy consumption of MBR outlet system in this way, not only can be reduced fouling membrane, but also can be energy-saving, can also be to out
Water pump plays a protective role, and extends water outlet pump service life, has certain novelty and stronger practicability.
A kind of low energy consumption constant flow of the utility model is discharged MBR device, including one is separated into MBR membrane cisterna and battery limits
Pond body, the MBR membrane module of MBR membrane cisterna is set, the electromagnetic flowmeter of battery limits is set, be arranged in battery limits water outlet take out

Air blower is connect to the pipeline between membrane module, connects membrane module to the pipeline between water outlet suction pump, connection water outlet suction pump is extremely
Pipeline between discharge outlet, connection electromagnetic flowmeter to the cable between PLC controller, connect PLC controller to frequency converter it
Between cable, connection frequency converter to water outlet suction pump between cable.It is characterized in that the electromagnetic flowmeter with 4 ~
The output of 20mA signal, the electromagnetic flowmeter are arranged in water outlet suction pump to the pipeline between discharge outlet.
A kind of low energy consumption constant flow of the utility model is discharged MBR device, and compared with prior art, it has following beneficial to effect
Fruit: 1, being discharged suction pump by frequency control, not only can be reduced fouling membrane, but also can be energy-saving, effectively reduces MBR outlet system
Operation energy consumption.2, suction pump is discharged by frequency control, can also played a protective role to water outlet pump, extended water outlet pump and use the longevity
Life.3, water outlet pump discharge is automatically controlled by PLC, without human intervention, high degree of automation saves labour cost.
Detailed description of the invention: Fig. 1 is the vertical structure schematic diagram of the utility model.
Specific embodiment: the utility model is described in further detail for specific embodiment with reference to the accompanying drawing, shown in Fig. 1
Structure is the one of preferred structure of the utility model, and it mainly includes one that it, which is a kind of low energy consumption constant flow water outlet MBR device,
