AI Technical Summary

Technical Problem

During the wastewater treatment process of existing duck pear vinegar production, the reaction time required in the biological treatment stage affects the efficiency, and the filtration of floats and impurities in the primary stage is prone to clogging and difficult to clean.

Method used

The drive assembly and transmission assembly are used to realize the alternate feeding of wastewater into and switching of biofilm filter cartridges between different chambers, combining scrapers and push plates to clean impurities, avoiding the use of a biofilm filter cartridge for a long time, improving treatment efficiency and facilitating cleaning.

Benefits of technology

It improves wastewater treatment efficiency, reduces intermediate waiting time, avoids secondary pollution, simplifies the impurity cleaning process, and enhances the continuity and stability of the system.

Abstract

The invention provides a pear vinegar production wastewater treatment process, which comprises a primary treatment box, the top of the primary treatment box is rotatably provided with a top plate, the bottom of the primary treatment box is fixedly provided with six groups of partition plates in equidistant circle center symmetry, the tops of the partition plates are rotatably provided with a first turntable, and a filter assembly is arranged between the first turntable and the top plate; the filtering assembly comprises a filtering frame, the filtering frame is located on the circle center axis of the primary treatment box, the bottom of the filtering frame is fixedly connected with the first rotating disc, and the top of the filtering frame penetrates out of the top plate. Compared with the prior art, through cooperation of the driving assembly and transmission, filtered wastewater is fed into different cavities for waiting, secondary pollution can be avoided, and the filtering efficiency is improved; the biological membrane filter cartridges are alternately fed into the biological treatment box, and the corresponding biological membrane filter cartridges are switched every time the chambers are switched, so that the situation that one biological membrane filter cartridge is used for a long time is avoided, the treatment efficiency is improved, the intermediate waiting time is shortened, and meanwhile, impurities accumulated in the primary treatment box are conveniently cleaned.
