Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] like figure 1 , 2 As shown, the bioreactor coupled with aeration and water collection membrane elements of the present invention includes an air supply pipe 6 , a water outlet pipe 5 , a membrane element 2 , packing 3 , a housing 7 , and a blower 4 .
[0020] Membrane elements 2 are distributed in the casing 7, and the membrane elements 2 are erected in rows in the casing 7. The membrane elements 2 are covered with fillers 3, the upper end of the membrane element 2 is connected to the air supply pipe 6, and the upper or lower end of the membrane element 2 is connected to the water outlet pipe 5. , The lower part of the housing 7 is provided with a sewage water inlet 1.
[0021] The outside is made up of shell 7, and shell 7 can be circular or square, can be fully closed or open, and when fully closed, can exert pressure to pool body. Sewage en...

The invention relates to a bioreactor coupled with aeration and catchment membrane elements. The bioreactor comprises a gas supplying pipe, a water outlet pipe, membrane elements, stuffing materials and a shell body. Membrane elements are distributed and arranged in the inner of the shell body, the membrane elements are arranged in rows in standing state in the inner of the shell body, stuffing materials are arranged out of the membrane elements, the gas supplying pipe is connected to the upper end of the membrane elements, the water outlet pipe is connected to the upper end or the lower end of the membrane elements, and the lower part of the shell body is provided with a sewage inlet opening. The membrane elements are in tube cylindrical shape. The shell body can be made into a round shape or a square shape. The bioreactor coupled with aeration and catchment membrane elements integrates aeration, strain, and solid / liquid separation process equipment together, and solves the problems that the devices are too many and not easy to repair, and production must be stopped for detection. The gas supplying and the water discharging operate in turns with intermittent, therefore anoxic / aerobic environment is formed in the equipment in turns, and bioprocess effect is better achieved. Air is induced into the membrane elements to have an anti-washing effect, and membrane pollution problem is improved. Stuffing materials are arranged on the membrane elements to increase MLSS in the water, and the processing effect is improved.
Description
technical field [0001] The invention relates to an industrial wastewater treatment device, in particular to a membrane bioreactor. Background technique [0002] With the continuous development of industry, the discharge of industrial wastewater continues to increase. Although most of the wastewater has been treated to meet the discharge standards, some wastewater is also discharged in an orderly manner, which will inevitably cause serious water pollution. At the same time, due to the shortage of water resources and the enhancement of people's awareness of environmental protection, the requirements for wastewater treatment are increasing day by day. For organic industrial wastewater with high concentration and refractory degradation, the traditional water treatment method has the disadvantages of low volume load of treatment equipment and large floor area. , Difficult to deal with, unstable effluent quality, complicated management and operation. In response to the above prob...
