A lithium battery waste liquid treatment device and treatment method

Abstract

The embodiment of the present application shows a lithium battery waste liquid treatment device and treatment method, including a waste liquid treatment body, a waste liquid treatment support seat, and a liquid collection tank. The waste liquid treatment support seat includes a support seat top plate, and the bottom of the support top plate is provided with The accommodating chamber of the waste liquid treatment body, the top of the top plate of the support seat is provided with a stirring rod accommodating stepped hole, the inside of the agitating rod accommodating stepped hole is provided with a waste liquid treatment column, and the inside of the agitating rod accommodating chamber is provided with a permeable membrane , Pour waste liquid into the waste liquid treatment column chamber, install the waste liquid treatment column in the stepped hole of the stirring rod, and set a mixture of iron and carbon inside the permeable membrane, and the iron and carbon form in the solution Tens of thousands of tiny primary batteries finally gather on the surface of iron and carbon, and finally cannot pass through the permeable membrane and return to the chamber of the waste liquid treatment column. The embodiment of the present invention provides a lithium battery waste liquid treatment device Reduce the cost of waste liquid treatment, reduce the difficulty of waste liquid treatment, and ensure the quality of effluent water.

Description

technical field [0001] The invention relates to the field of waste liquid treatment, in particular to a lithium battery waste liquid treatment device and treatment method. Background technique [0002] Lithium-ion battery is the rechargeable battery with the highest specific energy at present. Lithium-ion battery has the advantages of high working voltage, large specific energy, no pollution, no memory effect and long life. It is widely used in portable phones, digital cameras and notebooks. electrical installations. Lithium-ion battery electrolyte acts as a bridge connecting the positive and negative electrodes, transports lithium ions inside the battery, and acts as the "blood" of the battery. Lithium battery electrolyte is generally composed of a certain amount of organic solvent, electrolyte lithium salt, and necessary additives. Because high-concentration organic waste liquid generally has many characteristics such as high CODcr, low BOD5, biological toxicity or biode...

AI Technical Summary

Problems solved by technology

Because high-concentration organic waste liquid generally has many characteristics such as high CODcr, low BOD5, biological toxicity or biodegradable substances, large pH changes, high nitrogen and phosphorus content in some waste liquids, high salt content, and large fluctuations in water quality and water volume. One or more of them lead to complex components of waste liquid, difficulty in standard treatment, high investment and operating costs for waste liquid treatment, difficulty in standard treatment by conventional processes, and difficulty in finding effective and mature treatment technologies, making a large number of untreated and thorough organic The waste water drainage water environment has greatly affected the water ecological environment and threatened human health

The waste liquid has complex components, poor biodegradability, and certain toxicity

At present, physical and chemical methods are mainly used to treat this kind of waste liquid, such as chemical oxidation decomposition, chemical electrolysis, activated carbon adsorption and reverse osmosis. Difficult to guarantee
