[0002] Organic chemistry, also known as the chemistry of carbon compounds, is a science that studies the composition, structure, properties, preparation methods and applications of organic compounds. It is an extremely important branch of chemistry. Carbon-containing compounds are called organic compounds because chemists in the past believed that such substances must be produced by living things (organisms); however, in 1828, German chemist Friedrich Wöhler successfully synthesized urea (a biological molecule) in the laboratory for the first time. Since then, organic chemistry has deviated from the traditional definition and expanded to the chemistry of hydrocarbons and their derivatives. Wastewater is often produced in the production of organic chemistry.

[0003] Patent No. CN109264906A discloses a combined device for treating wastewater in an organic chemical laboratory. The treated organic laboratory wastewater passes through four cylindrical purification devices, namely, a macroporous resin adsorption device, an iron-carbon micro-electrolysis device, a BDD electrolysis device, and a photocatalytic device in sequence; wherein a cylinder wrapped with a macroporous resin is arranged in the macroporous resin adsorption device for adsorption; the device includes a wastewater inlet, a purified water outlet, and a valve for controlling the water flow of the inlet and outlet; the iron-carbon micro-electrolysis device includes a cast iron electrode and a carbon rod; the BDD electrolysis device includes a boron-doped diamond film electrode plate (BDD) and a power plug; the photocatalytic device includes a photocatalyst, an ultraviolet lamp, and a quartz glass protective cover; wherein the BDD electrode and the ultraviolet lamp are both connected to a laboratory power supply. The present invention has the advantages of simple operation, simple maintenance, energy saving, low cost, scientific and efficient when treating organic laboratory wastewater.

[0004] However, there are some problems in the use of existing multi-stage treatment equipment for organic chemical wastewater. 1. The multi-stage treatment equipment for organic chemical wastewater currently on the market lacks a good measure for rapid addition of reagents for neutralization treatment when treating it, thereby reducing the overall treatment efficiency and being inconvenient for rapid treatment. 2. The multi-stage treatment equipment for organic chemical wastewater currently on the market has low overall mixing when treating wastewater, thereby increasing the overall treatment time and reducing the efficiency and convenience. 3. The multi-stage treatment equipment for organic chemical wastewater currently on the market has low overall multi-stage circulation exportability when in use, and often requires manual classification, which increases the difficulty of treatment. 4. The multi-stage treatment equipment for organic chemical wastewater currently on the market lacks a solid absorption treatment measure that can be easily replaced when treating it, thereby reducing the overall treatment convenience and reducing the overall multiple treatment properties.
