This invention relates to the field of industrial organic wastewater pretreatment technology, and proposes a non-powered automatic proportioning device for pretreatment of polysaccharide alcohol wastewater. The device incorporates a proportioning component on the wastewater inlet pipe. This component includes an axially movable proportioning slide and a linked Venturi channel. The proportioning slide contains a proportioning pipe connected to the drug supply chamber. The polysaccharide alcohol wastewater flows through the Venturi channel under its own transport pressure, creating a negative pressure at the throat and driving the proportioning slide to displace. This simultaneously opens the wastewater passage and draws in the treatment solution, achieving non-powered automatic proportioning and premixing under high-viscosity wastewater conditions. The device uses a three-way valve to switch between direct discharge and automatic proportioning modes, improving the stability and uniformity of water-chemical mixing during the pretreatment of high-viscosity polysaccharide alcohol wastewater without requiring external power for dosing.
