| description | The invention discloses a potato production wastewater treatment method, which specifically comprises: 1, carrying out coarse filtration on potato production wastewater, drying the filter residue, and using the dried filter residue as a first feed raw material; step 2, filtering the filtrate obtained in the step 1 through an ultrafiltration membrane, and carrying out enzymolysis treatment on the filtrate by using protease; and step 3, filtering the enzymatic hydrolysate obtained in the step 2 through a nanofiltration membrane, and drying the concentrated solution to obtain a second feed raw material. The method has the advantages that a membrane integration technology is adopted to replace a traditional anaerobic treatment technology, the process is short in time consumption, small in occupied area and environmentally friendly, and effective components in wastewater can be recycled; besides, the influence of temperature and climate on the anaerobic biochemical technology is avoided, no peculiar smell exists, |
