Description

Crop cleaning waste liquid recycling system and treatment method thereof

The invention relates to a system for recycling waste liquid from cleaning crops and a treatment method thereof, in particular to a method for purifying and decomposing organic matters in waste liquid and improving acid-base quality (PH quality).

Generally speaking, after a large number of harvested rhizome plants (such as sweet potatoes and potatoes) are harvested, they need to be cleaned and sorted manually. During the cleaning process, a large amount of waste liquid will be generated. If the waste liquid contains decomposable organic matter, it can be discharged independently. Mortality increases, affecting the entire environmental ecosystem. At present, most of the treatment methods of domestic crop waste liquid use polyaluminum chloride chemical agent to improve the organic matter in the waste liquid, and use sodium hydroxide (NAOH) to neutralize the acid-base to reduce the acid-base quality (PH quality). However, the large amount of chemical agent used will pollute the environment, and water resources cannot be recycled and reused and the treatment cost is high. In view of this, the inventors conducted in-depth research and development and improvement, resulting in the present invention.
