Description

Starch wastewater treatment device

Technical Field

The utility model relates to wastewater treatment equipment, in particular to a starch wastewater treatment device, and belongs to the technical field of environment-friendly equipment.

Background

In the production of corn starch, a large amount of waste water is generated, the waste water mainly comes from drainage water after protein recovery in working sections of corn soaking, germ separation and washing, fiber washing, flotation concentration, protein filter pressing and the like, and evaporation condensate water generated in the recovery of corn soaking water resources, when the starch is produced by taking corn as a raw material, approximately 60% of corn can become commercial starch in absolute dry terms, 30% of corn becomes a byproduct, and the rest part of the waste water is discharged out of a factory. The corn starch wastewater generally comprises 0.3 percent to 0.7 percent of total sugar, 2.1 percent of crude protein, 5 percent to 10 percent of solid matter, 2 percent to 3 percent of crude fiber and 0.1 percent to 0.3 percent of fatty acid, the wastewater contains corn cortex, fiber and a small amount of small starch particles, has higher COD concentration and can be discharged only by treatment, the current common treatment mode is to filter the wastewater and then precipitate the wastewater, harmful gas in the water is taken away by continuous aeration in the precipitation process, and meanwhile, the generated oxygen-rich environment degrades and precipitates organic matters, the treatment mode has low cost, basically does not need chemical drugs and has little secondary pollution to the environment, when the treatment mode is adopted, the wastewater needs to be filtered firstly, the current filtration generally adopts a filter tank, and a filter plate or a filter bed is arranged in the filter tank, so as to intercept sundries in the wastewater, however, in use, as impurities trapped by the filter tank increase, the filtering capacity of the filter tank is greatly reduced, and the filter tank needs to be cleaned in time, at present, water inlet of the filter tank is generally stopped and the water is drained, filtered substances on the filter plate are cleaned manually, if the filter bed is used, the cleaning is more troublesome, and therefore, the operation efficiency of the system is influenced by a filtering process in starch wastewater treatment at present.
