A method for treating soy product wastewater to meet standards, applied to the device for treating soy product wastewater to meet standards as claimed in claim 1, characterized in that: The steps include: The soy product wastewater is transported to the interior of the filter box by using the liquid inlet pipe, and the wastewater is filtered by using the filter plate to remove impurities in the wastewater; In the process of filtering impurities in the wastewater, when one of the filter plates is in the filtering state, the retractable assembly corresponding to the other filter plate is started, and the pull rope and the pull ring cooperate to drive the other filter plate to slide into the installation box, and the cleaning assembly is used to clean the impurities attached to the current filter plate. After the cleaning is completed, the cleaned filter plate is inserted into the filter box under the cooperation of the retractable assembly and the restoring force of the connecting spring; The filtered wastewater is transported to the interior of the reaction tank through the liquid inlet, the pH value of the wastewater is detected in real time by the pH sensor, and the first pump body or the second pump body is started according to the detection result to transport alkaline solution or acid solution to the interior of the reaction tank to adjust the pH value of the wastewater; When adjusting the pH value of the wastewater, the stirring component is started to speed up the mixing speed of the wastewater and the acid or alkali solution, and the temperature sensor is used to detect the temperature in the reaction tank in real time. When the ambient temperature is low, the heating wire is started to heat the wastewater to ensure the reaction efficiency.
