Tail water treatment ecological benefit analysis method based on life cycle evaluation

By installing sensors in the effluent treatment system to monitor and preprocess data in real time, and combining this with the LCA method, a model of pollution products and ecological benefits is established. This solves the problem that existing technologies cannot comprehensively measure the ecological benefits of effluent treatment, and achieves a comprehensive, accurate, and intuitive assessment of ecological benefits.

AI Technical Summary

Technical Problem

Existing wastewater treatment effectiveness analysis methods cannot effectively measure the ecological benefits of the effluent treatment process, especially failing to include the ecological impacts caused by the consumption of production materials and energy in the analysis scope. Furthermore, traditional methods only measure the effectiveness through indicators such as chemical oxygen demand, which lacks comprehensiveness and accuracy.

Method used

Using a life cycle assessment-based approach, water quality and gas sensors are installed in the wastewater treatment system to monitor and preprocess data in real time. The LCA method is combined to establish a pollution product analysis model and an ecological benefit model, and to comprehensively assess the ecological impact of electricity consumption, chemical dosing and gas emissions.

Benefits of technology

It enables a comprehensive and accurate assessment of the ecological benefits of the wastewater treatment process, and provides an intuitive assessment of the ecological benefit level through ecological benefit indicators, thereby reducing the bias of the assessment results and improving the comprehensiveness and accuracy of the assessment results.

Abstract

The invention discloses a tail water treatment ecological benefit analysis method based on life cycle evaluation, which is based on operation of a tail water treatment system, a system water inlet module and a drainage module are provided with water quality sensors, and a treatment module is provided with a gas flow sensor and a gas detector. The water quality monitoring data and the gas monitoring data are transmitted to the data center and are preprocessed; the system is also provided with a medicament feeding device and an operation device; a pollution product analysis model is established based on an LCA method, the total pollution amount is calculated according to monitoring data, medicament putting data and operation data, and an ecological benefit model is established to analyze ecological benefits. The analysis method provided by the invention is based on life cycle evaluation, so that the analysis result is more comprehensive and accurate; the method comprises a preprocessing step, so that the influence of non-uniform concentration distribution on the accuracy of an evaluation result is avoided; and the ecological benefit model gives an evaluation grade, so that the evaluation result is more intuitive.
