Technical evaluation method for fermenting or chemical synthesis based pharmaceutical wastewater treatment

Abstract

The invention provides a technical evaluation method for fermenting or chemical synthesis based pharmaceutical wastewater treatment. The method comprises the following steps: constructing a pharmaceutical wastewater treatment technical evaluation index system; determining the weight of each level of index; confirming the relative importance grade of each level of index through expert consultation; constructing a pairwise comparison and judgment matrix; solving the characteristic vector of the matrix by adopting a mathematical method; determining the weight of each index through a consistency test; determining an evaluation index membership function; before assignment, normalizing all indexes, converting to values in an interval between 0 and 1; applying a lower semi-trapezoid expression formula to the quantitative factor membership function to obtain a quantitative membership function of each index; and finally formulating the best available technology screening criterion for water pollution prevention and control in the pharmaceutical industry. The method can be used for evaluating conventional water pollution prevention and control technologies in the pharmaceutical industry, provides technical guarantee for wastewater standard emission in the pharmaceutical industry, and provides technical support for the national water environment technology management system.

Description

technical field [0001] The invention relates to a technical evaluation method for pharmaceutical wastewater treatment, in particular to a technical evaluation method for fermentation or chemical synthesis pharmaceutical wastewater treatment. Background technique [0002] Pharmaceutical wastewater mainly includes antibiotic production wastewater, synthetic drug production wastewater, and washing water and flushing wastewater in the production process of various preparations. Among them, fermentation and chemical synthesis pharmaceuticals are the focus and difficulty of pollution control in the pharmaceutical industry. The wastewater is characterized by organic matter High content, complex and changeable components, heterocyclic and refractory substances, strong inhibition to microorganisms, high toxicity, deep color and high salt content, especially poor biochemical properties, and intermittent discharge, are difficult to treat of industrial wastewater. The current technical...
