Machining emulsified waste liquid reduction treatment system and treatment method thereof

Abstract

The invention discloses a machining emulsified waste liquid reduction treatment system, and the system comprises an emulsified raw liquid box, a filter, a three-stage series advanced oxidation box, reverse osmosis water treatment equipment, a water production tank and a low-temperature evaporator, wherein the emulsified raw liquid box is connected with the three-stage series advanced oxidation box through the filter; the three-stage series advanced oxidation tank is connected with the reverse osmosis water treatment equipment, the water production tank and the low-temperature evaporator are respectively connected with the reverse osmosis water treatment equipment, and the water production tank is connected with the low-temperature evaporator. The invention further discloses a reduction treatment method of the system for the emulsified waste liquid. According to the system, the machining emulsified waste liquid is sequentially subjected to sedimentation, demulsification, reverse osmosis filtration, step-by-step concentration and the like, so that the emission amount of emulsified waste liquid of an enterprise can be reduced by more than 90% while the standard discharge of concentrated liquid obtained by effluent can be efficiently ensured in an energy-saving manner, the treatment cost is remarkably reduced, and the system has multiple benefits of environmental protection, sustainability, recycling and the like, and is suitable for industrial production. The method is a brand-new processing mode for reducing the machining emulsified waste liquid.

Description

technical field [0001] The invention relates to the technical field of machining emulsified waste liquid treatment, in particular to a machine processing emulsified waste liquid reduction treatment system and a treatment method thereof. Background technique [0002] Emulsion (commonly known as cutting fluid) is a metalworking fluid widely used in machinery manufacturing and other processing industries. It mainly plays the role of cleaning, cooling, lubrication, and rust prevention. After repeated use, the emulsion will Problems such as spoilage and performance degradation occur, thus becoming "emulsified waste liquid". The composition of the emulsified waste liquid is very complex. Its surface not only contains solid suspended matter such as metal powder, but also contains soluble organic matter such as surfactants and mineral oil, making it extremely difficult to treat. [0003] At present, there are about 7 million machine tools in my country, and the annual discharge of ...

Problems solved by technology

The composition of emulsified waste liquid is very complex. Its surface not only contains solid suspended matter such as metal powder, but also contains soluble organic matter such as surfactant and mineral oil. It is extremely difficult to treat

[0003] At present, there are about 7 million machine tools in my country, and the annual discharge of emulsified waste liquid is as high as 40 million tons, and the annual treatment cost exceeds 100 billion yuan. Such a large amount of emulsified waste liquid greatly increases the operating burden of enterprises and increases operating costs. At the same time If a large amount of emulsified waste liquid is not properly disposed of, it will also have a serious impact on the environment
