Embodiment Construction

[0037] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0038] see figure 1 , the present embodiment a kind of hyodeoxycholic acid production wastewater treatment process, comprises the following steps:

[0039] cool down S101 :

[0040] cooling of wastewater containing fatty acids, mucins and heterocholic acids to below 10°C;

[0041] first acidification S102 :

[0042] Adjust the cooled waste water to PH=5-6, milky white appears, immediately stop the acidification adjustment;

[0043] S103 : Stir the wastewater for 5-10 minutes until the solution becomes clear;

[0044] Second acidification S104 :

[0045] Slowly adjust the waste water to PH=2-3 to generate flocculent sediment;

[0046] S105 : Stand for one hour to form the upper layer of acid water and the lower layer of floc...

Abstract

The invention relates to a treating process for pig deoxycholic acid production wastewater. The treating process includes the steps of cooling: cooling the wastewater containing fatty acid, mucoprotein and impure cholic acid water to a temperature lower than 10 DEG C; primary acidizing: adjusting the PH (potential of hydrogen) value of the cooled wastewater to range from 5 to 6 and stopping acidizing when milk white color shows up, and stirring the wastewater for 5-10 minutes till the wastewater becomes clear; secondary acidizing: adjusting the PH value of the wastewater to range from 2 to 3 so as to enable the wastewater to form flocculent sediments, and standing for a period of time to form upper acid water and lower flocculent sediments. Step-by-step acidizing of the wastewater is finished at a low temperature: the wastewater is primarily acidized to adjust the PH value to be equal to 5-6 and is then stirred for several minutes until black fluid sediments are generated; most of the bile pigments, the mucoprotein and the fatty acid settle at the first, and then the wastewater is secondarily acidized to adjust the PH value to be equal to 2-3 to enable the flocculent impure cholic acid to settle, so that the fatty acid, the mucoprotein and the impure cholic acid left in the wastewater can be removed effectively, and the BOD (biochemical oxygen demand) in the wastewater can be decreased.

Description

technical field [0001] The invention relates to a waste water treatment process, in particular to a hyodeoxycholic acid production waste water treatment process. Background technique [0002] Hyodeoxycholic acid is a cholic acid extracted from pig bile, white or slightly yellowish powder, bitter in taste. Smell slightly fishy. Slightly soluble in alcohol, slightly soluble in acetone, very slightly soluble in ether and chloroform, almost insoluble in water. It can inhibit the formation of cholic acid and dissolve fat, reduce blood cholesterol and triglycerides, and is suitable for type Ia or type Ib hyperlipidemia and atherosclerosis, and has certain effects on pertussis bacillus, diphtheria bacillus, staphylococcus aureus, etc. It can also be used as an anti-inflammatory drug to treat chronic bronchitis and viral upper respiratory tract inflammation in children. However, the wastewater generated during the production of hyodeoxycholic acid contains a large amount of resid...
