Removal Efficiency and Performance Optimization of Organic Pollutants in Wastewater Using New Biochar Composites

Abstract

The purpose is to optimize the catalytic performance of biochar (BC), improve the removal effect of BC composites on organic pollutants in wastewater, and promote the recycling and sustainable utilization of water resources. Firstly, the various characteristics and preparation principles of new BC are discussed. Secondly, the types of organic pollutants in wastewater and their removal principles are discussed. Finally, based on the principle of removing organic pollutants, BC/zero valent iron (BC/ZVI) composite is designed, among which BC is mainly used for catalysis. The effect of BC/ZVI in removing tetracycline (TC) is comprehensively evaluated. The research results reveal that the TC removal effect of pure BC is not ideal, and that of ZVI is general. The BC/ZVI composite prepared by combining the two has a better removal effect on TC, with a removal amount of about 275 mg/g. Different TC concentrations, ethylene diamine tetraacetic acid (EDTA), pH environment, tert-butanol, and calcium ions will affect the TC removal effect of BC composites. The overall effect is the improvement of the TC removal amount of BC composites. It reveals that BC has a very suitable catalytic effect on ZVI, and the performance of BC composite material integrating BC catalyst and ZVI has been effectively improved, which can play a very suitable role in wastewater treatment. This exploration provides a technical reference for the effective removal of organic pollutants in wastewater and contributes to the development of water resource recycling.

Photocatalytic degradation of drugs and dyes using a maching learning approach

“…[32][33][34][35] Hence, this information can be used to optimize the design and operation of wastewater treatment systems, ultimately leading to the more efficient removal of organic pollutants from the environment. [36][37][38] Machine learning algorithms play a crucial role in predicting the catalytic degradation performance of organic pollutants in wastewater treatment processes. They enable researchers and engineers to analyze large amounts of data and identify patterns and relationships that may not be easily discernible through traditional analytical methods.…”
