Embodiment Construction
[0035] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0036] refer to figure 1 , a method for treating waste water from the production of heparin sodium sausage casings described in this specific embodiment, comprising the following
[0037] Process steps:
[0038] , Centrifugal separation: Enzymolysis extracts the waste water produced in the production of heparin sodium as raw water, mixes the raw water and flocculant and pours it into the centrifuge 1, and removes the protein suspension in the raw water by the centrifugal force generated by the high-speed rotation of the centrifuge 1 matter, to obtain protein clarified solution I;
[0039] , primary filtration: use the fine filter device 3 to filter the protein clarified liquid I obtained in step 1 to remove the remaining solid impurities to obtain liquid II;
[0040] , secondary filtration: the liquid II obtained in step 2 is further filtered through ...

The invention relates to a method and a device of treating heparin sodium casing production wastewater. The wastewater generated in heparin sodium enzymolysis and extraction production is subjected tocentrifugal separation, primary filtration, secondary filtration, concentration, spray drying, drying and reverse osmosis treatment to achieve recovery and extraction of a high-concentration protein;the purified wastewater can be recycled; a clear liquid outlet of a centrifuge is communicated with a liquid inlet of a liquid collection tank; a liquid outlet of the liquid collection tank is communicated with a refined filtration device through a delivery pump A; the refined filtration device is communicated with a water inlet of a nanofiltration membrane filtration device through a delivery pump B; a water outlet of the nanofiltration membrane filtration device is communicated with a reverse osmosis membrane device; a turbid liquid outlet of the nanofiltration membrane filtration device iscommunicated with a feed port of a falling film evaporator A; and a discharge port of the falling film evaporator A is communicated with a spray dryer. The method and the device have the benefits that the recovery and extraction of the high-concentration protein are achieved, the purified wastewater is recycled, the environmental pollution is reduced, and at the same time, economic benefits are improved.
Description
technical field [0001] The invention relates to a method and a device for treating waste water, in particular to a method and a device for treating waste water from heparin sodium casing production. Background technique [0002] Heparin sodium is a biomedical intermediate, which has anticoagulant and antithrombotic effects, and has a very high clinical value in terms of blood oozing and acute myocardial infarction in patients with kidney disease. more. At present, in the production process of enzymatic hydrolysis and extraction of heparin sodium, the discharged enzymatic hydrolysis wastewater not only contains a large amount of suspended solids, but also contains a relatively high concentration of organic pollutants such as protein. Wastewater directly discharged into rivers and lakes without treatment will consume a large amount of dissolved oxygen in the water body, make the water body corrupt, deteriorate the water quality, and cause serious pollution to the environment....
