Filtering device for bioreactor

Abstract

A filtering device for a bioreactor comprises a filtering box body, a containing space is formed in the middle of the filtering box body, a guide-in opening communicated with the containing space is formed in the upper end of one side wall of the filtering box body, a cleaning opening communicated with the containing space is formed in the lower end of one side wall of the filtering box body, and a filtering cylinder is arranged in the containing space. An eduction tube is arranged at the upper end of the filter cartridge, the eduction tube upwards penetrates out of the filter box body, and a cover body is arranged above the filter cartridge. After the cover body ascends, the space at the upper end of the accommodating space is reduced, so that the water pressure entering the accommodating space through the guide-in opening is gradually increased, and furthermore, turbulent flow is formed in the accommodating space through the increase of the water pressure, so that microorganisms for purification and organic matters in the liquid are sufficiently and quickly combined, the purification rate is improved, and the purification effect is improved through the impact effect of the turbulent flow. The outer side face of the filter cartridge is impacted and cleaned, and the situation that too many suspended solids accumulate on the outer surface of the filter cartridge to affect the filtering effect is avoided.

Description

technical field [0001] The invention relates to the technical field of biopharmaceuticals, in particular to a filtering device for a bioreactor. Background technique [0002] As we all know, biopharmaceutical enterprises will produce a large amount of sewage in the production process, and the sewage contains a large amount of organic matter. The current conventional method is to use membrane bioreactors for treatment. The working principle is to first introduce the sewage into the reactor, and then use the biological treatment technology to fully decompose and transform the organic pollutants in the sewage, and then use the effective separation of the ultrafiltration membrane and the microfiltration membrane to complete the solid-liquid separation of the sewage. separation, and finally achieve the purpose of purifying sewage. [0003] The high-efficiency separation effect of membrane technology makes the suspended substances, colloidal substances, and microbial flora in the...

Problems solved by technology

However, the suspended matter in the wastewater will form accumulation on the filter device, resulting in clogging and affecting the filtering effect. The filter cartridge needs to be removed and washed frequently, which reduces the working efficiency and increases the cost of use.
