Abstract
The utility model provides an ethyl acetate effluent treatment mechanism, include the aeration tank of being connected with the waste water discharging end, the aeration tank passes through aeration mud pump and the first entrance point connection of MBR membrane cisterna, the play clear liquid end of MBR membrane cisterna passes through the clean water pump and is connected with fire-fighting tank moisturizing or production water end. The utility model has the advantages that: the water quality of the discharged water of the mechanism is stable and reliable, and the water quality of the discharged water can be reused as primary water, so that the water energy consumption of ethyl acetate production is greatly reduced.
Description
Technical Field
The utility model belongs to the technical field of waste water treatment, especially, relate to an ethyl acetate wastewater treatment mechanism.
Background
The ethyl acetate is also called as ethyl acetate, has low toxicity and sweet taste, has pungent smell when the concentration is higher, is easy to volatilize, and is a fine chemical product with wide application. The aeration tank utilizes an activated sludge method to treat sewage, and a certain sewage retention time is provided in the tank to meet the oxygen quantity required by aerobic microorganisms and the mixing condition of full contact of sewage and activated sludge. The existing treatment mode is that after the aeration mixed liquor is settled by a settling tank, supernatant fluid overflows to a clear water collecting tank, sludge at the bottom returns to an aeration tank to continuously clear up various indexes in the wastewater, and the process is relatively simple. But the sedimentation equipment in the mode is easily influenced by the flow of the aeration liquid lifting pump and the flow of the sludge return pump, so that the effluent is relatively turbid, and the treatment efficiency of the ethyl acetate wastewater is greatly influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve foretell technical problem, provide an ethyl acetate effluent treatment mechanism.
The purpose of the utility model is realized through the following technical scheme:
ethyl acetate effluent disposal mechanism, include the aeration tank of being connected with the waste water discharge end, the aeration tank passes through aeration mud water pump and MBR membrane cisterna first entrance point connection, the play liquid clear end of MBR membrane cisterna passes through the clean water pump and is connected with fire-fighting pool moisturizing or production water end.
Preferably, the second sludge outlet end of the MBR membrane tank is connected with the aeration tank.
Preferably, two aeration muddy water pumps are arranged in parallel.
Preferably, the liquid outlet end of the aeration sludge water pump is also connected with a sludge press filtration treatment mechanism.
Preferably, a clean water tank is arranged between the MBR membrane pool and the clean water pump.
Preferably, two clean water pumps are arranged in parallel.
The utility model has the advantages that: the water quality of the discharged water of the mechanism is stable and reliable, and the water quality of the discharged water can be reused as primary water, so that the water energy consumption of ethyl acetate production is greatly reduced.

Detailed Description
The utility model particularly discloses an ethyl acetate effluent treatment plant constructs, it is shown with combination figure 1, include the aeration tank 1 of being connected with the waste water discharge end, aeration tank 1 is through aeration mud water pump and the first entrance point connection of MBR membrane cisterna 2. Clear liquid end of MBR membrane cisterna 2 is connected with clear water tank 3, clear water tank 3 passes through the clean water pump and is connected with fire pond moisturizing or production water end. The second sludge outlet end of the MBR membrane tank 2 is connected with the aeration tank 1 through a pump (not shown in the figure). The utility model discloses promote aeration liquid to MBR reaction tank, separate out the clear solution after membrane filtration, mud returns the mud pump and returns good oxygen aeration tank and continue to handle.
In this embodiment, the aeration slurry pumps are arranged in parallel and are a first aeration slurry pump 4 and a second aeration slurry pump 5. In order to improve the utilization rate of the aeration liquid, the liquid outlet ends of the first aeration mud pump 4 and the second aeration mud pump 5 are also connected with a sludge filter-pressing treatment mechanism. And valves are arranged on corresponding connecting pipelines, so that part of the aeration liquid can be selectively introduced into the sludge press filtration treatment mechanism for treatment, or the aeration liquid is lifted to the MBR reaction tank for membrane filtration. According to the water outlet requirement, the membrane in the MBR reaction tank can be replaced by a micro-filtration membrane, an ultrafiltration membrane, a nanofiltration membrane, a reverse osmosis membrane and the like.
For the efficiency that improves, the clarified water pump is provided with two side by side, is first clarified water pump 6 or second clarified water pump 7 respectively, and the effect that parallels not only can raise the efficiency, can also regard as reserve.
The utility model provides an among the prior art phenomenon that the play water is turbid, improved ethyl acetate effluent disposal efficiency greatly.
The utility model has a plurality of specific implementation modes. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
