AI Technical Summary

Technical Problem

Existing water treatment catalysts are inefficient in treating livestock and poultry manure and are unable to effectively remove antibiotic pollutants. Furthermore, the ammoniation of the amino group increases the total nitrogen load in the water, hindering direct contact between pollutants and the catalyst surface, thus increasing the difficulty of purification.

Method used

Waste pigeon manure is converted into an iron-doped biomass resource-based water treatment catalyst. The catalyst surface utilizes ammonia ions to mediate the local hydrogen bond network distortion of H2O molecules, achieving self-purification of antibiotic wastewater. Through mechanical ball milling and cascade roasting processes, a dual reaction center structure is formed, promoting the mass transfer of pollutants and dissolved oxygen.

Benefits of technology

This method rapidly removes multiple antibiotics from water without the need for external oxidants or energy. It features low energy consumption, low cost, high efficiency, and maintains stability during long-term reactions, enabling efficient utilization of agricultural waste and purification of new pollutants.

Abstract

This invention relates to the field of water treatment, specifically to an iron-doped biomass resource-based water treatment catalyst, its preparation method, and its application. The preparation of the water treatment catalyst includes the following steps: Step 1, drying and dehydrating recovered pigeon manure; Step 2, finely sieving the dried pigeon manure; Step 3, heat-treating the purified pigeon manure in a muffle furnace to obtain resource-based biochar; Step 4, ball milling dopamine hydrochloride, ferric chloride hexahydrate, and resource-based biochar at a mass ratio of 1:(5-15):(80-100); Step 5, calcining the ball-milled material in a tube furnace at 850-950℃. The water treatment catalyst provided by this invention can rapidly reduce the antibiotic content in wastewater, while accelerating antibiotic removal under ammonia nitrogen conditions. It achieves long-term continuous purification during long-term reaction, exhibiting good stability and removal effect, and is beneficial for achieving low-cost treatment of agricultural waste and efficient purification of new pollutant wastewater.
