The invention provides a filtering and treating device for wastewater produced by the lithium battery industry and an application method thereof. The filtering and treating device comprise a wastewater collection device, a microporous filter and a separating device which is communicated with the output end of the wastewater collecting device through a connecting pipe. According to the filtering and treating device for wastewater produced by the lithium battery industry and the application method thereof, through cooperation of the arranged wastewater collecting device, the arranged microporousfilter and the like, a set of efficient and complete filtering system is formed; during long-term filtration of wastewater, through cooperation among all the equipment, wastewater treatment time is shortened, and treatment effect is not greatly influenced; and a water quality detector is additionally arranged to finally detect the wastewater to be discharged, and if the content of harmful substances in the wastewater is too high, the wastewater is conveyed into the microporous filter through a water pump for treatment again, so the discharged wastewater is prevented from polluting the surrounding environment.
Description
technical field [0001] The invention relates to the field of wastewater treatment, in particular to a device for filtering and treating wastewater in the lithium battery industry and a method for using the same. Background technique [0002] The lithium battery industry mainly produces lithium-related products. The common lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, lithium metal The processing, storage, and use of cellulose have very high requirements on the environment. With the development of science and technology, lithium batteries have become the mainstream now. [0003] The lithium battery industry will produce a large amount of wastewater in the production process, and the wastewater contains a large amount of harmful substances, which cannot be discharged at will. The general industrial practic...
