Embodiment 1

[0039] A pharmaceutical company mainly produces a variety of pharmaceutical intermediates, including L-glutamine, zinc acetate and red yeast rice. The total amount of discharged water is 1000t / d, the influent COD is about 3000mg / L, and the ammonia nitrogen is about 200mg / L. The plant mainly produces L-glutamine, and there is a requirement for reuse of water. When L-glutamine production is stopped or equipment is overhauled, there is no requirement for reuse. The water quality after treatment can meet the discharge requirements and can be discharged outside. See the table below for the water quality of the incoming and outgoing water.

Embodiment 2

[0042] A pharmaceutical company mainly produces a variety of pharmaceutical intermediates, including nitrochlorobenzene, vanillin and p-aminophenol. The discharged water is 2500t / d of nitrochlorobenzene, 500t / d of vanillin and 1500t / d of p-aminophenol, and 500t / d of other domestic and production wastewater, totaling 5000t / d. The sewage outlet of the plant is set in a seasonal river. According to the requirements of the local environmental protection bureau, drainage can be carried out from March to November every year, and discharge is not allowed in the dry season of December, January and February. Therefore, there are recycling requirements in December, January and February, and all wastewater is reused without being discharged outside. There is no recycling requirement in other months, which reduces the cost of wastewater treatment. The content of ammonia nitrogen in this water is relatively high, so the second-level biochemical module and the fourth-level biological turnta...

Abstract

The invention relates to the technical fields of environmental management and recycling, and concretely relates to a modular integration system for treating medicine intermediate production wastewater. Process integration and parameter design are carried out against the treatment problem of high-concentration mixed organic wastewater generated in the production process of medicine intermediate manufacturers. The modular integration system comprises a solid-liquid separation module, a primary pretreatment module, a secondary biochemical module and a third depth treatment module, an online monitoring system is arranged at a water inlet end, is used to acquire and analyze water quality information and outputs a result to an automatic control system, and the automatic control system emits a signal to all the modules in order to enforce automatic control. The system has the characteristics of flexibility, high efficiency, convenience and intelligence, and can ensure the economical, effective and stable running of a wastewater treatment facility.

Description

technical field [0001] The invention relates to the technical field of environmental governance and resource utilization, in particular to a modular integrated system for treating pharmaceutical intermediate production wastewater and its working method Background technique [0002] The organic wastewater produced in the pharmaceutical production process is recognized as one of the sources of serious environmental pollution. In 2009, there were 6,807 pharmaceutical companies in my country, and the total amount of wastewater discharge reached 527.18 million tons. The pharmaceutical industry accounted for 1.72% of the country's total industrial output value, and the pharmaceutical industry Wastewater accounts for 2.52% of the total industrial wastewater discharge. Therefore, the pharmaceutical industry has been included in the national environmental protection plan as one of the 12 key industries for treatment, and the wastewater produced by the pharmaceutical industry has becom...
