Catalyst mother liquid treatment recycling system and treatment technology thereof

Abstract

The invention discloses a catalyst mother liquid treatment recycling system and a treatment technology thereof. The catalyst mother liquid treatment recycling system comprises a mother liquid separation unit, a mother liquid evaporating unit and a drying powdering unit which are connected sequentially, a stock solution of the catalyst mother liquid is connected with an input end of the mother liquid separation unit through a stock solution conveying pipe, a primary concentrated liquid output end of the mother liquid separation unit is connected with an input end of the mother liquid evaporating unit through a first concentrated liquid conveying pipe, a condensed water output end of the mother liquid separation unit is connected with a biochemical treatment water pool of water through a first condensed water conveying pipe, a secondary concentrated liquid output end of the mother liquid evaporating unit is connected with an input end of the drying powdering unit through a second concentrated liquid conveying pipe, a condensed water output end of the mother liquid evaporating unit is connected with the biochemical treatment water pool of water through a second condensed water conveying pipe and a third condensed water conveying pipe, and an output end of the drying powdering unit is connected with a dry powder packaging unit.

Description

technical field [0001] The invention relates to the technical field of industrial waste water treatment system and treatment process, in particular to a catalyst mother liquor treatment and recycling system and its treatment process. Background technique [0002] Residential, commercial, agricultural, and industrial water use generates large volumes of untreated wastewater that can cause health hazards as well as environmental problems. As a result, most cities use wastewater treatment plants downstream of their sewage collection systems to treat raw wastewater into a less harmful form. [0003] Wastewater entering a treatment plant (influent) is approximately 99% water and 1% a mixture of large objects, solids, dissolved solids, oils, waxes, and organics. The latter can be separated from the former by using a series of processing steps, commonly referred to as preprocessing, primary processing, secondary processing, and advanced processing. Pretreatment and primary treatm...

Problems solved by technology

[0005] The generation and treatment of these end products, and the routine operation of wastewater treatment plants may not be ideal

For example, the continuous discharge of treated wastewater into nearby water bodies can be harmful to the environment

In addition, the sludge produced creates a strong odor that makes the area near the wastewater treatment plant uninhabitable or habitable
