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

Embodiment 1

[0040] Such as figure 1 As shown, a penicillin wastewater biointensification treatment device of the present embodiment includes a hydrolytic acidification zone 1, a moving bed biofilm zone 2 with a suspended filler 8, an advanced treatment zone with a suspended filler 8 and a membrane module 10 3. The penicillin wastewater to be treated is processed through the hydrolytic acidification zone 1, the moving bed biofilm zone 2 and the advanced treatment zone 3 in sequence. Among them, the hydrolytic acidification zone 1 is used for pretreatment of penicillin wastewater to improve the biodegradability of penicillin wastewater and degrade some pollutants, and the advanced treatment zone 3 is the main biological treatment area of ​​penicillin wastewater. The bottom of the hydrolytic acidification zone 1 is provided with a stirring device 4, and its top is provided with a three-phase separator 5. The hydrolysis acidification zone 1 is connected to the water inlet at the bottom of the...

Embodiment 2

[0054] Such as figure 1 As shown, a penicillin wastewater biointensification treatment device of the present embodiment includes a hydrolytic acidification zone 1, a moving bed biofilm zone 2 with a suspended filler 8, an advanced treatment zone with a suspended filler 8 and a membrane module 10 3. The penicillin wastewater to be treated is processed through the hydrolytic acidification zone 1, the moving bed biofilm zone 2 and the advanced treatment zone 3 in sequence. The bottom of the hydrolytic acidification zone 1 is provided with a stirring device 4, and its top is provided with a three-phase separator 5. The hydrolysis acidification zone 1 is connected to the water inlet at the bottom of the moving bed biofilm zone 2 through an outlet pipe 102, and the outlet pipe 102 is provided with a first pump 103 . In this embodiment, the suspended packing 8 in the moving bed biofilm area 2 and the advanced treatment area 3 is all selected from polyethylene packing, and the fillin...

Embodiment 3

[0075] Such as figure 1 As shown, a kind of penicillin wastewater biointensification treatment device of the present embodiment has the same basic structure as that of the embodiment 1, the difference is that the suspended filler 8 inside the total moving bed biofilm area 2 and the advanced treatment area 3 of the present embodiment adopts poly Propylene filler, and the filling ratio of the filler is 60% of the effective volume of the moving bed biofilm zone 2.

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...
