Penicillin waste water biological enhancement treatment device and method

Abstract

The invention discloses a penicillin waste water biological enhancement treatment device and method, and belongs to the technical field of waste water treatment and environmental protection. According to the device, the characteristics of multiple sewage treatment devices such as a sequencing batch type reactor, a membrane bioreactor and a moving bed bio-membrane reactor are integrated; the device mainly comprises a hydrolytic acidification area, a moving bed bio-membrane area provided with suspended filler, and a deep treatment area provided with a membrane assembly and suspended filler. The hydrolytic acidification area is used for pretreating waste water, improving biodegradability of the penicillin waste water and degrading a part of pollutants, and the deep treatment area is a main penicillin waste water biological treatment system. According to the penicillin waste water biological enhancement treatment device and method, the treatment efficiency of the penicillin waste water can be effectively improved, the occupied area can be reduced, the effluent quality can be kept stable, the service life of an aerating device and the membrane assembly can be prolonged, maintenance and operating cost can be reduced, and the penicillin waste water biological enhancement treatment device and method are especially suitable for treating the antibiotic waste water with large water quality and amount changes.

Description

technical field [0001] The invention belongs to the technical fields of wastewater treatment and environmental protection, and more specifically relates to a penicillin wastewater biointensified treatment device and treatment method that integrates the advantages of multiple bioreactors. Background technique [0002] Penicillin wastewater refers to the wastewater produced by pharmaceutical companies during the production of penicillin or other wastewater containing high concentrations of penicillin. It has complex components, high concentrations of pollutants and suspended solids, contains a large number of refractory substances, and often has excessive nitrogen. And residual penicillin and its by-products lead to its strong microbial toxicity and inhibition. At present, there are many methods for the treatment of penicillin wastewater, which can be mainly divided into two categories: physical and chemical treatment and biological treatment. Among them, physical and chemical...

AI Technical Summary

Problems solved by technology

This application can improve the biological denitrification treatment effect of nitrogen-containing organic industrial wastewater to a certain extent, but for penicillin wastewater, due to the large fluctuation of water quality and quantity, the method of this application is not suitable

In addition, the method of this application always discharges water through the membrane filter module, which will increase the cleaning frequency of the membrane module, shorten the service life of the membrane, and increase the operating cost

In addition, the moving bed biofilm reactor and the internal circulation membrane bioreactor in this application are two independent reaction devices, which also leads to a large area required for them, resulting in an increase in infrastructure costs
