Abstract

The invention relates to a technology for realizing environment-friendly and pollution-free discharging of penicillin production wastewater and belongs to the field of wastewater treatment and reutilization. According to the technology for realizing environment-friendly and pollution-free discharging of the penicillin production wastewater, penicillin wastewater after biochemical and physical treatment is treated with combination techniques of UF (ultrafiltration), RO (reverse osmosis), SRO (super reverse osmosis) and MED (multiple effect distillation), and water produced by a membrane system and boiler steam condensation water are recycled in a production workshop; on one hand, water resources are saved, so that the water resources are efficiently and sustainably utilized, on the other hand, environment-friendly and pollution-free discharging of the wastewater is realized, and the environment protection problem about wastewater is thoroughly solved; the technology has remarkable environmental benefit, economic benefit and social benefit and is an effective way for cyclic utilization of water resources and environmental protection.

Description

technical field [0001] The invention relates to a technology for realizing environmental protection and non-discharge of production wastewater, in particular to a technology for realizing environmental protection and non-discharge of penicillin production wastewater, which belongs to the field of wastewater treatment and reuse. Background technique [0002] Penicillin wastewater has a high concentration of organic matter and contains high concentrations of sulfate radicals and surfactants, making it difficult to treat. The biochemical treatment of penicillin wastewater includes aerobic treatment, anaerobic treatment and aerobic-anaerobic combined treatment, etc., and the physical and chemical treatment includes air flotation, Fenton, micro-electrolysis and other treatment technologies. After biochemical and physicochemical treatment of the wastewater, the indicators such as COD and chroma of the wastewater were significantly reduced, but the salinity and COD of the wastewate...
