Equipment and method for removing proteins through membrane method

Abstract

The invention relates to equipment and method for removing proteins through a membrane method. The equipment comprises a raw water tank connected to a control valve V03, wherein the control valve V03is connected to a circulating valve, the circulating valve is connected to a concentrated water return pipe, the concentrated water return pipe is connected with a membrane assembly, the membrane assembly is connected to a circulating pipe, the circulating pipe is connected to an effluent branched pipe, the effluent branched pipe is connected to a control valve V06, the control valve V06 is connected to a one-way valve, the one-way valve is connected to a backwashing branched pipe, the backwashing branched pipe is connected to a backwashing pump, the backwashing pump is connected to a backwashing pipe, the backwashing pipe is connected to a backwashing waster tank, the backwashing pipe is connected to a chemical feed pipe, the chemical feed pipe is connected to a control valve V08, the control valve V08 is connected to a chemical feed pump, and the chemical feed pump is connected to a medicament tank. The equipment is used for removing the proteins through the membrane method.

Description

Technical field: [0001] The invention relates to a device and a method for removing protein by a membrane method. Background technique: [0002] Since salted duck egg pickling waste brine is high salt water, a few duck eggs will break during the pickling process, and egg white and egg yolk liquid will be mixed into the pickling water, resulting in the waste water containing microbial cells, water-soluble proteins, eggshell extracts, egg white and egg yolk Exudate and other components, so the water body is turbid, the smell of eggs is heavy, the color is dark and bitter, and the hygiene and safety are low, so it cannot continue to be marinated in a cycle. [0003] The factory will use a lot of salt and water in the pickling process. If it is discarded directly, the production cost of the factory will rise sharply. At the same time, if the pickling wastewater with high salt and high COD is directly discharged, it will cause surrounding water bodies (death of aquatic organisms)...

Problems solved by technology

[0002] Since salted duck egg pickling waste brine is high salt water, a few duck eggs will break during the pickling process, and egg white and egg yolk liquid will be mixed into the pickling water, resulting in the waste water containing microbial cells, water-soluble proteins, eggshell extracts, egg white and egg yolk Exudate and other ingredients, so the water body is turbid, the smell of eggs is heavy, the color is dark and bitter, and the hygiene and safety are low, so it cannot continue to be marinated in a cycle

[0003] The factory will use a lot of salt and water in the pickling process. If it is discarded directly, the production cost of the factory will rise sharply. At the same time, if the pickling wastewater with high salt and high COD is directly discharged, it will cause surrounding water bodies (death of aquatic organisms), ecological environment ( crops dying) destroyed
