Embodiment 1

[0027] Embodiment 1: a kind of processing method of three wastes in the enzymatic production of hydroxyproline process, it is characterized in that containing following steps:

[0028] (1) Process waste gas: the main source of waste gas pollution in the present invention is the dust-containing waste gas produced in the drying and packaging section of the production process. The dust-containing waste gas is discharged through a 15m high exhaust cylinder after electrostatic dust removal for raw material processing, and its dust removal efficiency is >99%. The emission dust concentration meets the requirements of the "Comprehensive Emission Standard of Air Pollutants";

[0029] (2) Wastewater treatment: domestic and production sewage is treated by the sewage treatment station in the factory area and reaches the "Extraction Pharmaceutical Industry Water Pollutant Discharge Standard" (GB 21905-2008) and is discharged into the river through the sewage pipe network. The sewage treatme...

Abstract

The invention relates to a method for treating three wastes during enzymatic production of hydroxyproline. The method comprises the following steps: process exhaust gas treatment, wastewater treatmentand solid waste treatment. The production process and control of the production process are both designed well according to requirements of clean production, and measures of energy conservation and environmental protection are arranged in energy consumption indexes, material consumption indexes, water consumption indexes, pollutant emission control and other aspects; and the method meets the requirements of clean production well, reaches the domestic advanced level, and has a high level of recycling economy, and water, gas, solid waste and other matter are comprehensively utilized to some extent.

Description

technical field [0001] The invention relates to a method for treating three wastes in the process of enzymatically producing hydroxyproline. Background technique [0002] Hydroxyproline (Hyp) is an imino acid, which is the product of hydroxylation of L-proline, and its molecular formula is C5H9NO3. Hydroxyproline is white flaky crystal or crystalline powder, slightly sweet, with a melting point of 274°C, easily soluble in water and slightly soluble in ethanol. According to the position of hydroxylation of hydroxyproline, it can be divided into 3-hydroxyproline (3-Hyp) or 4-hydroxyproline (4-Hyp). Because hydroxyproline has two asymmetric carbon atoms, there are 4 stereoisomers. Trans-4-hydroxyproline is more common in nature. Trans-4-hydroxyproline was first found in animal collagen protein. [0003] The production methods of amino acids at home and abroad mainly include fermentation method, enzymatic method, proteolytic extraction method, and chemical synthesis method. ...
