Plasma pesticide residue removing and cleaning wastewater purifying and recycling integrated machine Technical Field The utility model relates to the technical field of atmospheric pressure plasmas. More particularly, the utility model relates to a plasma pesticide residue removing and cleaning wastewater purifying and recycling integrated machine. Background In recent years, the problem of food safety caused by the fact that cleaning work of fruit and vegetable processing pretreatment is not in place is a great challenge for modern food processing, for example, food-borne diseases can be caused by microorganism residues, and pesticide residues can cause long-term potential harm to human health. The demands of residents on multidimensional nutrition health foods are increased, and the full-utilization processing of fruits is particularly realized by cleaning, so that the problem of removing or degrading harmful substances such as pesticide residues is solved. The existing cleaning technology comprises running water flushing, disinfectant such as chlorine dioxide and the like or special cleaning agent for fruits and vegetables cleaning, ultrasonic cleaning, ozone water cleaning, electrolyzed water cleaning and the like, the cleaning effects of different cleaning modes are different, and the problems of cost input and sustainable development of environment-friendly emission of cleaning wastewater exist, so that the development of the safe, efficient and emission-reducing green cleaning technology is significant.
