Description
[technical field]
The utility model relates to a kind of waste disposal plant, particularly a kind of MBR device of sewage disposal.
[background technology]
Membrane bioreactor (Membrane Bioreactor, MBR) be a kind of new and effective wastewater treatment and reuse technology, it utilizes membrane separation plant that active sludge in the biochemistry pool and macromolecular substance are held back, thereby hydraulic detention time and sludge retention time can be controlled respectively, and the material of difficult degradation constantly reacts in reactor, degrades, and saves second pond simultaneously.Adopt the MBR equipment of oxidation ditch to have aerobic, anoxic and anaerobic biological treatment effect, good waste water treatment effect to difficult degradation, the high ammonia nitrogen of high density, and floor space is little, energy consumption is low, yet common waste disposal plant has just used oxidation ditch or tubular membrane separately, and processing and filter effect are limited.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of MBR waste disposal plant, and it can improve sewage disposal and filtering effect, and realizes automatization control.
The utility model is achieved in that
A kind of full-automatic device that is used for the MBR sewage disposal of the utility model, it comprises an oxidation ditch, described oxidation ditch is provided with dissolved oxygen detector, mud turbidity detector, frequency transformer, surface aeration machine, described frequency transformer connects described surface aeration machine, described oxidation ditch is connected to a tubular membrane by a water transfer pump, and described dissolved oxygen detector, mud turbidity detector, frequency transformer, water transfer pump, tubular membrane all are connected to an automatic control device.
Further, described oxidation ditch is double-deck oxidation ditch.
Further, described automatic control device is for adopting the control device that DDC (direct digital controller) mode is controlled or PLC (programmable logic controller) mode is controlled.
Advantage of the present utility model is:
1. the utility model uses double-deck oxidation ditch and tubular membrane simultaneously, carries out the biological treatment and the filtration of sewage simultaneously, better effects if;
2. dissolved oxygen detector of the present utility model, mud turbidity detector, frequency transformer, water transfer pump, tubular membrane have all connected automatic control device, realize intellectuality, use more convenient;
3. the flooding quantity of water transfer pump of the present utility model can be regulated by automatic control device, has effectively improved the life-span of tubular membrane;
4. automatic control device 5 of the present utility model can satisfy the requirement of full factory system management to upper computer by every component parameter in the MBR device of the double-deck oxidation ditch of ethernet real-time Transmission.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
[embodiment]
See also shown in Figure 1ly, embodiment of the present utility model is described in detail.
As shown in Figure 1, embodiment of the present utility model, it comprises an oxidation ditch 1, described oxidation ditch 1 is provided with dissolved oxygen detector 11, mud turbidity detector 12, frequency transformer 13, surface aeration machine 14, described frequency transformer 13 connects described surface aeration machine 14, and described oxidation ditch 1 is connected to a tubular membrane 3 by a water transfer pump 2.Described dissolved oxygen detector 11, mud turbidity detector 12, frequency transformer 13, water transfer pump 2, tubular membrane 3 all are connected to an automatic control device 5.As figure, described oxidation ditch 1, water transfer pump 2, tubular membrane 3, and product pond 4 is connected in turn.
Described oxidation ditch 1 is energy-saving double-deck oxidation ditch, has promptly adopted the oxidation ditch of double-deck four ditch formulas, and described surface aeration machine is arranged in the upper strata.The utility model is by automatic control device 5 sequential operations, cooperate and carry out components and parts, components and parts comprise surface aeration machine 14, water transfer pump 2, frequency transformer 13 and dissolved oxygen detector 11, mud turbidity detector 12, regulate the dissolved oxygen efficiency of described oxidation ditch 1, stablize the sewage oxygen dissolving value of oxidation ditch 1, make oxidation ditch form tangible aerobic zone, oxygen-starved area and anaerobic zone.Described automatic control device 5 adopts the DDC mode to control or the PLC mode is controlled.
Principle of work is as follows: described automatic control device 5 receives the numerical value that dissolved oxygen detector 11 collects, the frequency of control of conversion device 13, thereby the wheel speed of control surface aerator 14, the dissolved oxygen content of adjusting oxidation ditch 1.Described automatic control device 5 receives the numerical value that mud turbidity detector 12 collects, and in conjunction with the numerical value of dissolved oxygen detector 11, control water transfer pump 2 is regulated the water yield that enters tubular membrane 3.
The utility model detects oxygen dissolving value and sludge concentration in the oxidation ditch 1 in real time by adopting described dissolved oxygen detector 11 and mud turbidity detector 12, by the output frequency of oxygen dissolving value control of conversion device 13, thus control surface aerator 14, thus dissolved oxygen efficiency regulated; Reach the content of controlled oxidation ditch 1 dissolved oxygen.
Described automatic control device 5 can integrated ethernet mouth, and the parameter by every components and parts in the ethernet real-time Transmission MBR device satisfies the requirement of full factory system management to upper computer.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
