Abstract

The invention relates to the technical field of starch wastewater treatment, and particularly relates to a treatment process for potato starch production wastewater. Starch extraction wastewater is pretreated by addition of an acidity regulator, flocculation lumps are formed; and a part of the flocculation lumps is precipitated at the bottom of a flow tank during flowing; the wastewater is naturally placed in a wastewater collection tank for more than 120 days, and then enters a wastewater filter tank for performing filtration treatment; a flocculant is added, precipitation is performed for 2-3 hours after stirring; and the wastewater after flocculation treatment enters an anaerobic system and an aerobic biochemical system in order to further purify the water quality to meet a discharge standard. Objects of the potato starch wastewater treatment process are to solve the problem of wastewater treatment in small and medium-sized potato starch, and to solve the problems of large investment, long start-up period, waste of waste water resources, non-standardized water discharge and high operation cost of sewage treatment equipment in a wastewater treatment process.

Description

technical field

[0001] The invention relates to the technical field of starch wastewater treatment, in particular to a treatment process for potato starch production wastewater. Background technique

[0002] Classified according to the source of starch raw materials, potato starch can be divided into tapioca starch, sweet potato starch, potato starch and other varieties. Since the processing technology and raw material properties of banana taro, kudzu root and potato starch are similar, their waste water has common characteristics and the treatment method is the same .

[0003] Sweet potatoes, also known as sweet potatoes, are perishable and should not be stored for a long time. The deep processing of sweet potatoes can solve the phenomenon of a large number of rotten potatoes caused by improper storage of fresh potatoes. The refined starch of sweet potatoes can be processed in different depths to produce hundreds of valuable products, and the value-added is about 10-30 tim...
