Problems solved by technology

However, this method not only consumes a lot of manpower, material resources and financial resources, but also takes a long time for treatment, but the effect is not obvious. Therefore, in the whole long process of membrane regeneration, it is impossible to ensure that the treated water quality meets the discharge standards.
In addition, the biological filler used in sewage biological treatment is currently treated as general waste, and there are certain safety hazards in the treatment

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 Shown is an activation and regeneration device for suspended biological fillers according to the present invention, which includes a film removal device 5 , a filter device 13 and a cleaning device 11 . The stripping device 5 is equipped with a stripping agent, and the dried filler 1 can be put into it for pre-stripping, so that the biofilm on the surface of the filler 1 is partially detached. The stripping device 5 is also provided with a mechanical stirrer 4, which can stir the stripping agent and improve the stripping efficiency. The filter device 13 is provided with a screen 6 at the top, and a sump 8 with a valve 9 at the bottom. After the release agent containing the exfoliated biofilm in the sump 8 is precipitated, the release agent is clarified. A transfer pipe is provided between the sump 8 and the stripping device 5,...

Abstract

The invention relates to a method and a device for activating and regenerating suspended active biological packing. The device comprises a demolding device, a filtering device and a cleaning device, wherein a release agent is contained in the demolding device; aired packing can be put into the demolding device to carry out premolding; a filter net is arranged on the upper part of the filtering device; a liquid collecting tank with a valve is formed in the bottom of the filtering device; clean water is contained in the cleaning device; and meanwhile, a reciprocating vibration screen and a plurality of ultrasonic generators with the vibration screen are also arranged in the cleaning device to further demold the packing. According to the device and the method, the activating and regenerating efficiency of the suspended packing can be effectively improved; the production cost of manpower, material resources and financial resources is reduced; the economic benefits are improved; meanwhile, the effective specific surface area of the activated packing can restore to be 70%-90% of new packing; and growth and reproduction of microorganisms and guarantee of biomass are facilitated.

Description

technical field [0001] The invention relates to a method for treating biological fillers, in particular to a method for activating and regenerating suspended active biological fillers, and a device for realizing the method. Background technique [0002] At present, the biofilm method has been widely used in the sewage treatment process, and has shown a unique purification comprehensive performance. In the sewage, the suspended physicochemical sludge is continuously absorbed by the filler, and the accumulation of inactive physicochemical sludge accumulates over time, and the active biofilm is continuously wrapped, so that the specific surface area of ​​the filler is continuously reduced, and the filler becomes heavy and settles to the bottom of the tank for fluidization And the oxygen transmission rate of the filler gradually decreases, the microorganisms in the inner layer of the filler die due to lack of oxygen and nutrients, and the microorganisms wrapped in the physical s...
