Potato-like starch processing waste water treatment agent and waste water treatment method

Abstract

The present invention provides a potato starch processing water treating agent and water treating method, the treating agent utilizes acid wash prepared by acid wash de-ironing process and alkali wash prepared by alkali wash removing SiO2 process as coagulation settling agent A and neutralizing sorbent B in the implementing course of ZL01144627.7 and 200410034004.8 , waste of the potato starch process is treated by acidating coagulation sedimentation and absorption treatment, above 80% nutrientsubstance in waste is trapped via serum drainage and muddy staying, for producing animal feeding-stuffs additive or fermenting biogas, changing harm to benefit, multipurpose use; supernatant fluid after being neutralizing absorption treatment sending to biology clarifier-tank is drained via water plant physiology purification, to eliminate water pollution and damage in the potato starch process.

Description

technical field [0001] The invention relates to a potato starch processing wastewater treatment agent (hereinafter referred to as treatment agent) and a wastewater treatment method for potato starch processing wastewater (hereinafter referred to as wastewater), belonging to the field of agricultural and sideline product processing wastewater treatment. Background technique [0002] Potato crops are widely planted for their high yield, high efficiency, drought and flood tolerance, and barrenness tolerance. The production of starch from potato crops is an important means for farmers to process and add value to agricultural products. It has excellent economic benefits and strong market demand. An important industry for poverty alleviation and prosperity. Potato starch processing will discharge a large amount of wastewater, which is rich in various dissolved sugars, potato resin, protein, fiber and other nutrients. It will be discharged into the water body without treatment, res...

Problems solved by technology

This undoubtedly killed the industry, cut off the income of farmers who produce starch, and caused a strong reaction from farmers. Every time the starch production season of sweet potatoes is harvested, on the one hand, governments at all levels organize various forces to ban potato starch production everywhere. On the one hand, farmers use guerrilla tactics to produce in every possible way. Farmers are dissatisfied with government intervention affecting their income. Fish farmers complain that government measures are ineffective and fish and shrimp die. This creates tension between cadres and the masses, and social conflicts intensify, seriously affecting the construction of a harmonious society.

Therefore, providing an efficient and cheap potato starch processing wastewater treatment agent and wastewater treatment method can fundamentally eliminate the problem of wastewater pollution, change the blockage into dredging to achieve a win-win environment and benefits, and create a stable and harmonious relationship between the cadres and the masses. The strong requirements and vision of the production area, but the potato starch wastewater has complex components, scattered locations, and concentrated time, making it very difficult to treat
