Abstract

The invention discloses a preparation method of a water purifying agent, which comprises the following steps: mixing zirconium isopropoxide and isopropanol, and carrying out ultrasonic treatment to obtain a solution A; adding polyethylene oxide-polypropylene oxide-polyethylene oxide triblock copolymer into a mixed solution of ethanol and methanol, and carrying out ultrasonic treatment to obtain asolution B; dropwise adding the solution A into the solution B, and carrying out ultrasonic treatment; carrying out aging treatment at room temperature, and drying; calcining the prepared solid in a muffle furnace to prepare mesoporous zirconium oxide; crushing and washing pineapple peel, and adding the pineapple peel into deionized water for boiling; cooling to room temperature, filtering, and collecting filtrate; and adding a mixture of zinc acetate dihydrate and the prepared mesoporous zirconia into the filtrate, carrying out ultrasonic treatment, then dropwise adding a sodium hydroxide solution, carrying out stirring treatment, then carrying out centrifugation, and carrying out drying treatment on precipitates obtained by centrifugation so as to prepare the water purifying agent. The preparation method is simple to operate and mild in condition, and the prepared water purifying agent is large in surface area and multiple in adsorption active sites and can well remove organic pollutants in printing and dyeing wastewater.

Description

Technical field: [0001] The invention relates to the field of wastewater treatment, in particular to a water purifying agent and a preparation method thereof. Background technique: [0002] In recent years, with the rapid development of the national economy, the printing and dyeing industry has also entered a period of rapid development, but the printing and dyeing industry is a large discharge of industrial wastewater. Large changes and other characteristics, is difficult to treat industrial wastewater. Printing and dyeing wastewater is a complex organic wastewater with organic pollution as the main component. The main objects of treatment are COD, BOD, organic matter that is not easy to biodegrade or biodegrades slowly, alkalinity, dyes and pigments, and a small amount of toxic substances. In order to solve the environmental pollution caused by organic dyes, different methods and technologies have been used to treat the wastewater containing dyes, and some progress has be...
