Embodiment 1

[0018] Weigh 200g of fresh turmeric (measure water content 63.10%) and add 200ml of water, and grind into a fine slurry. Add 0.3 g of α-amylase, raise the temperature to 85-90° C. for 0.5 h, and keep stirring for 1 hour. Lower the temperature to 60°C, add 0.5 g of glucoamylase, adjust the pH to 3.8-4.0, and keep stirring for 1 hour. After the enzyme was inactivated at 100°C under normal pressure for 5 minutes, it was first naturally filtered, and then press-filtered to obtain 130ml of sugar solution with a sugar content of 11.5. The filter residue was added with 200ml of water and 50ml of concentrated hydrochloric acid, hydrolyzed at normal pressure for 6 hours, and filtered under reduced pressure to obtain 430ml of filtrate (1), with a sugar content of 13.5. The filter residue was rinsed with 785ml of water to about pH=6.5, dried, and the weight of the dried hydrolyzate was weighed to be 13.9866g.

[0019] Get 400ml of filtrate (1), and distill it under normal pressure: whe...

Abstract

The invention provides a treatment method for brown Windsor soap element industrial waste water and the synthesis utilization. The method hydrolyses brown Windsor by acid, filters out the high acidity organic waster water, reclaims the acid and water by distilling method, the distilled remained liquid is filtered, the solid can be used as reclaimed soap element or medical or harmless farm insecticide. The filtered liquid is put into ground phosphorite and produces the phosphate fertilizer, or be reclaimed as acid to be sued circularly. The cleaning water of the dregs are poured into biological pool.

Description

technical field [0001] The invention relates to a physical and chemical treatment method of high-concentration acid-containing organic wastewater, in particular to a treatment method and comprehensive utilization of turmeric saponin industrial wastewater. Background technique [0002] The use of distillation to treat high-concentration organic wastewater has been very common in the field of organic wastewater treatment technology. The waste liquid after acid hydrolysis of turmeric is a kind of high-concentration organic wastewater with high acid content (2N), and terminal biochemical treatment technology is mostly used now. The use of this technology not only has high operating costs, which are difficult for enterprises to bear, but also has a large load of terminal neutralization and biochemical treatment, making it difficult to meet emission standards. Among the existing methods of turmeric saponin industrial wastewater treatment, some have begun to use distillation to re...
