Problems solved by technology

The current treatment method is that the intestinal membrane protein is obtained by filtering, concentrating, and spray-drying the wastewater. The intestinal membrane protein is easily digested and absorbed by piglets, but it has a unique fishy smell of the small intestine, and its use is limited.

Embodiment

[0022] The waste water produced by enzymatic hydrolysis of heparin sodium is 5000 liters. Add 10 kg of polyaluminum chloride and 50 ppm of polyacrylamide with a molecular weight of 6 million and stir evenly. After 5 hours of precipitation, the precipitate accounts for 1 / 4 of the total volume of the liquid, namely: 1250 liters, the volume of the supernatant was 3750 liters. The supernatant is concentrated by nanofiltration membrane with a molecular weight cut-off of 100 Daltons, 3000 liters of water passing through the nanofiltration membrane is recovered and recycled, and the volume of the remaining concentrated solution is 750 liters. Combine the primary precipitate and concentrated solution to obtain 2000 liters, adjust PH = 2 with sulfuric acid, let it stand for 4 hours to settle, the supernatant liquid is 800 liters, and filter it again after siphoning, and add hydrogen peroxide 2.5 to the remaining 1200 liters of secondary precipitate kg, bleached for 4 hours, and concent...

Abstract

The invention discloses a method for preparing a nutrient phagostimulant by utilizing heparin wastewater. The method comprises the following steps: extracting wastewater generated by heparin by an enzymolysis method; adding a flocculant for precipitating to obtain a primary precipitate and a supernate; performing concentration by nanofiltration on the supernate; recovering and recycling the clean water which passes through a nanofiltration membrane; merging the concentrate and the primary precipitate; adding an acid to adjust the PH to be 2 to 3; performing secondary precipitating; siphoning the supernate; adding a decolorizer into the remaining precipitate for decolorizing; performing vacuum concentration on the decolorized remaining precipitate; adding amino acids and saccharides into the obtained vacuum concentrate for performing a Maillard reaction; spray-drying to obtain the phagostimulant. According to the method, water resource is recovered and utilized; the environment is purified; the economic benefit is improved; the unique stench of small intestines is improved by the prepared phagostimulant; the palatability and the food calling property of pets are enhanced; the phagostimulant is rich in nutrients, and is applied to pet staple food or pet snacks or anthony pig and chicken feed as an additive.

Description

technical field [0001] The invention relates to a treatment method for heparin wastewater, in particular to a method for preparing a nutrient attractant by using heparin wastewater. Background technique [0002] At present, heparin is mainly produced by enzymatic hydrolysis in industry. The raw material is pig small intestinal mucosa. The production process is as follows: fresh pig small intestinal mucosa is added with protease. Decompose for 2 to 4 hours, inactivate the enzyme, and filter with an 80-mesh sieve to obtain the filtrate. The filtrate is added with macroporous cationic adsorption resin to absorb heparin, and then filtered, eluted, alcohol precipitated and dried to obtain crude heparin. [0003] In the process of extracting heparin by enzymatic hydrolysis, a large amount of wastewater is generated at three process nodes: 1. Adsorption wastewater is generated after resin adsorption; 2. Elution wastewater is generated after resin elution; 3. Heparin is precipitate...
