The accessories of the multifunctional efficient membrane bioreactor include an MBR, a disinfecting device, a metering device and an electric control device, wherein a sponge ball aerating apparatus is arranged inside the MBR. By adopting the design of the aerating mode, a place for lodging and inhabiting microbes is provided, the oxygen utilization rate is increased, the number of the effective microorganism is increased, the sludge concentration is increased, the biochemical reaction is very efficient and the hydraulic retention time is shortened, so that the water treatment capacity in unit time is increased, the size of the device is shrunk and the floor space is reduced.
Description
Technical field
The present invention relates to a kind of multifunctional efficient membrance bioreactor, belong to biochemical process field of water treatment equipment.
Background technology
The efficient combination of MBR membrane separation technique and biological treatment, its origin is the second pond replaced by membrane separation technique in activated sludge process, carries out solid-liquid separation.This technique not only effectively reaches the object of mud-water separation, and has the incomparable advantage of tertiary sewage treatment traditional technology.Sponge ball aerating apparatus is added in original MBR membrane cisterna, the unique design of sponge ball, make aerating system bubble more even, the vesicular structure of sponge ball, provide habitat to microorganism, and can start the very first time to utilize dissolved oxygen, improve the utilization ratio of oxygen, add the concentration of microorganism, improve biochemical efficiency.
What existing MBR membrane cisterna adopted is perforated pipe aerating regulation, and aeration is uneven, the place that microorganism does not perch, and is unfavorable for the breeding of microorganism.The vesicular structure of sponge ball, provide a large amount of ground of living away from home to microorganism, after microbubble occurs, be disseminated to uniformly in water body through sponge ball, the microorganism very first time make use of the oxygen in bubble.Improve coefficient of oxygen utilization, improve microorganism active, improve microbiological treatment efficiency, save energy, save floor space.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of multifunctional efficient membrance bioreactor, overcomes membrane cisterna aeration in prior art uneven, the problem that coefficient of oxygen utilization is low, improve sludge concentration further simultaneously, increase the quantity of effective bacterium, improve processing efficiency, reduce equipment volume.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: MBR is the efficient combination of membrane separation technique and biological treatment, and its origin is the second pond replaced by membrane separation technique in activated sludge process, carries out solid-liquid separation.This technique not only effectively reaches the object be separated against the current, and has the incomparable advantage of tertiary sewage treatment traditional technology.Add the MBR membrane cisterna of sponge ball aerating apparatus, microbial growth is bred faster, sludge concentration does not comparatively have Packed MBR pond higher, and make volumetric loading higher, sludge loading is lower.There is the general characteristic of MBR membrane cisterna simultaneously.
Accompanying drawing explanation
Fig. 1 is a kind of multifunctional efficient membrance bioreactor of the present invention structural representation.
In accompanying drawing, the list of parts representated by each label is as follows:
1, membrane support 1,2, aerating pipelines, 3, sponge ball, 4, membrane module, 5, Chi Ti.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of multifunctional efficient membrance bioreactor of the present invention, comprises pond body 5 membrane support 1, aerating pipelines 2, sponge ball 3, membrane module 4, pond body 5.Pond body 5 is rectangular parallelepiped or the uncovered pond of square build, built-in membrane module 4, membrane module 4 is apart from 300 ~ 500mm at the bottom of pond, apart from pond body 5 upper end 600 ~ 800mm, aerating pipelines 2 is placed at 100mm place at the bottom of concrete pond, aerating pipelines 2 is fixedly connected with clamp with pond body 5, and membrane module 4 is fixed by membrane support 1, and collects the connection of mouth use pipeline at the product water of port.At the bottom of pond, the aerating pipelines 2 of tiling at intervals uses threeway upwards to divide out branch, and branch road is upwards every the punching of certain distance, and hole circumferentially distributes, and uses diameter 50mm sponge ball 3 to wrap up outside hole.Establish two position meter in pond, low liquid level collects mouth 300mm apart from membrane module 4 upper end, and high liquid level collects mouth 500mm apart from membrane module 4 upper end.Dissolved oxygen on-line computing model is established in membrane cisterna.
Membrane module 4 water producing pipe establishes stopping valve, under meter, vacuum pressure gauge between road to vacuum primingpump, for automatic control.Backwashing pump is established on water producing pipe road, and inlet ductwork connects water producing pipe road, pipeline establishes stopping valve, valve open during backwash, water producing pipe road valve closes; Produce penstock during normal product water to open, backwash pipe valve is closed.Produce in water tank and establish apparatus for ultraviolet disinfection.
Automatic control system is run automatically for controlling whole system, according to the data of dissolved oxygen on-line computing model, controls the aeration rate of blower fan; Control the start and stop of vacuum primingpump according to the two position of membrane cisterna, high liquid level starts vacuum primingpump, and low liquid level stops vacuum primingpump; Control backwash according to vacuum pressure gauge and under meter, vacuum pressure gauge reading becomes large, and under meter flow reduces, stop vacuum primingpump, close and produce penstock, open backwash valve, open backwashing pump and carry out backwash to membrane module 4, the backwash regular hour stops, and is switched to and normally produces aqueous mode; According to the power of the flow control ultraviolet ray sterilizing device of product water.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
