Problems solved by technology

However, the complex synthesis route of lincomycin also makes its production waste liquid be organic wastewater with high concentration, high chroma and heavy odor. The COD in organic wastewater is extremely high, and the water quality, water volume, pH value and temperature fluctuate greatly, and Lincomycin, which inhibits the growth of microorganisms, remains in the organic wastewater, and direct discharge will have a certain impact on the soil. Therefore, the wastewater produced by lincomycin must be properly treated
[0003] The traditional process of treating organic wastewater is a biochemical method, but the lincomycin contained in the wastewater producing lincomycin will inhibit or even kill the biochemical bacteria, resulting in poor treatment effect and high cost of biochemical treatment

Embodiment 1

[0098] according to figure 1 The method for treating the lincomycin production wastewater by the membrane treatment system of the shown lincomycin production wastewater includes:

[0099] Lincomycin production wastewater (wastewater produced when lincomycin is produced by fermentation with Streptomyces lincoeum) is pre-precipitated in the waste liquid tank for 3 hours to obtain the primary precipitation supernatant;

[0100] The initial precipitation supernatant was put into the sedimentation tank, and 15 ppm of polyaluminum chloride and 5 ppm of polyferric sulfate were added in sequence, stirred, flocculated and precipitated for 2 hours, and the supernatant of precipitation was obtained.

[0101] The precipitated clear liquid is filtered through a multi-media, and the filter medium of the multi-media filter is a layer of coarse quartz sand, a fine quartz sand and an anthracite layer stacked in sequence; the coarse quartz sand is the bottom layer; the coarse quartz sand is Th...

Abstract

The invention provides a membrane treatment method and system for lincomycin production wastewater, and belongs to the technical field of wastewater treatment. According to the membrane treatment method, multi-medium filtration, first precision filtration, ultrafiltration filtration, second precision filtration, nanofiltration filtration and reverse osmosis are adopted, impurities in the lincomycin production wastewater are sequentially removed from large molecular weight to small molecular weight, and then the aim of recovering lincomycin can be achieved through the evaporation process; and meanwhile, the interference of particulate matters and macromolecular matters in the wastewater on the lincomycin is solved. A reducing agent and a scale inhibitor are added, so that the membrane element is prevented from being polluted and blocked in the long-term operation process, and the service life of the membrane element is prolonged.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a membrane method and system for treating wastewater produced by lincomycin. Background technique [0002] With the development of socialization, there are more and more various domestic pharmaceutical factories, and the drugs produced are not only simple raw materials, but drugs with high added economic value, and lincomycin is one of them. However, the complex synthesis route of lincomycin also makes its production waste liquid be organic wastewater with high concentration, high chroma and heavy odor. The COD in organic wastewater is extremely high, and the water quality, water volume, pH value and temperature fluctuate greatly, and Lincomycin, which inhibits the growth of microorganisms, remains in organic wastewater, and direct discharge will have a certain impact on the soil. Therefore, the wastewater produced by lincomycin must be properly treated. [0003] Th...
