Problems solved by technology

This significantly increases the production cost per unit of product
At the same time, the up-to-standard discharge of this dilution method is not in line with the national industrial policy
[0005] For this reason, all lincomycin manufacturers have done a lot of work around the advanced treatment of wastewater, and the following methods are commonly used, such as: one is the advanced treatment method of membrane filtration. The characteristic of this method is that the water quality obtained through membrane filtration is the best. Good, but the processing facilities are complicated, the investment is large, the

Abstract

The invention relates to a lincomycin wastewater advanced treatment and water recycling technology. The technology is a complete wastewater treatment process consisting of four steps, namely wastewater treatment, activated sludge treatment, advanced treatment of activated carbon bed desorption solution and biogas recycling, wherein the filtrates of the activated sludge treatment, the advanced treatment of activated carbon bed desorption solution and the biogas recycling all enter a wastewater treatment collection pool to be subjected to circular treatment. The lincomycin wastewater treated by the technology has a wide range of application; the technology has the advantages of excellent pollutant removal effect, low operating cost, stability and reliability, and is convenient to operate; and when the treated wastewater meets the standards, the obtained water can replace industrial water to be directly used in industrialized production, thus the emissions of pollutants in the operation of the system can be reduced, the pollution of the wastewater to the environment can be eliminated, and remarkable economic benefits and social benefits can be obtained.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a process for advanced treatment of lincomycin waste water and reclaimed water. Background technique [0002] After the national waste water COD discharge standard was raised, the waste water treatment task was placed in front of the pollution control production enterprises, especially the deep treatment of lincomycin waste water has always been troubled by the waste water discharge standard of the production enterprises, which is an enterprise environmental protection management The bottleneck has become the focus of attention of various lincomycin manufacturers. [0003] In the production process of lincomycin, the waste water produced has the characteristics of large amount of waste water, high concentration of organic matter, deep color, high content of inorganic salt, complex composition, and poor biodegradability. to serious pollution. After being discharged into...
