Embodiment Construction

[0030] like figure 1 Shown, the present invention handles lincomycin class antibiotic production waste water, and main procedure has:

[0031] 1) The lincomycin-type antibiotic production wastewater discharged from the production workshop flows into the regulating pool by itself. The regulating pool plays the role of equalizing the water quality and regulating the water volume. The hydraulic retention time is 4.0-6.0h, and the effluent is pumped to the heating pool by the sewage lifting pump installed at the bottom of the pool.

[0032] 2) Wastewater enters the heating pool. Heating is carried out by the steam passing into the heating pool, the heated water temperature is controlled at 34-36°C, and the hydraulic retention time of the heating pool is 15 minutes.

[0033] 3) The effluent from the heating pool flows into the anaerobic reaction sedimentation tank by gravity. The hydraulic retention time of the anaerobic reaction sedimentation tank is 27.0h.

[0034] The compos...

Abstract

The invention relates to a technology for processing wastewater generated in lincomycin antibiotic production. Acidic anaerobic bacteria can degrade biologically degradation-resistant polymer organicsubstances into biologically degradable micromolecular organic substances; the B / C ratio of wastewater can be increased to 0.26-0.30; aerobic bacteria can degrade biologically degradable micromolecular organic substances in wastewater into inorganic substances such as CO2, H2O, etc.; thus COD can be effectively removed; through oxidation of ozone, most of residual organic substances can be oxidized and decomposed into inorganic substances; then the wastewater can be filtered by active carbon so as to remove organic substances and inorganic substances such as heavy metals, ammonia nitrogen, etc. in wastewater through filtering and adsorption; and the COD of effluent is less than 100 mg / L. The provided technology can effectively process wastewater generated in lincomycin antibiotic production; the processing effect is good, the water quality of the effluent is stable; the COD concentration of the effluent is smaller than 100 mg / L, and the operation cost is reasonable.

Description

technical field [0001] The invention relates to a process for treating industrial waste water, in particular to a process for treating waste water produced by lincomycin antibiotics. Background technique [0002] For a long time, lincomycin antibiotic production wastewater has become one of the difficulties in wastewater treatment in the pharmaceutical industry due to its characteristics of high COD concentration, various toxic and harmful substances, poor biodegradability, high SS concentration, and high salt concentration. As my country's environmental protection and pollution prevention and control requirements become more and more stringent and ruled by law, the improvement of wastewater treatment technology in the pharmaceutical industry is becoming more and more urgent. [0003] For many years, in order to achieve good treatment effects, the core technical model of reasonable lincomycin production wastewater treatment is basically the same as the "anaerobic + aerobic" ...
