Green environment-friendly absorption carrier for phenol wastewater

Abstract

The invention discloses a green environment-friendly absorption carrier for phenol wastewater, which is characterized by comprising the following components in parts by weight: 10-15 parts of kaolin, 0.3-0.5 part of thickener, 0.1-0.3 part of wetting agent, 0.3-0.5 part of dispersing agent, 50-60 parts of oyster shell powder, 3-9 parts of phosphoric acid, 5-14 parts of concentrated hydrochloric acid, 14-26 parts of ethanol, 5-16 parts of ammonia water, 3-6 parts of gallic acid, 2-6 parts of citric acid, 1-6 parts of kieselguhr, 10-25 parts of acrylate, 3-8 parts of hydrochloric acid, 5-14 parts of ferric sulfate, 3-8 parts of ammonia water, 1-8 parts of gallic acid, 30-45 parts of shell powder, 5-16 parts of kieselguhr, 5-16 parts of meerschaum and 10-35 parts of medical stone. The porous spongy composite material, which is prepared by using a fiber substrate as a carrier that carries a high polymer material, improves the problem of poor biocompatibility of the simple resin adsorbent, and can carry microbes on the composite material to complete the degradation of phenol.

Description

technical field [0001] The invention relates to a green and environment-friendly absorption carrier for phenol wastewater. Background technique [0002] Phenol-containing wastewater is a common highly toxic and refractory organic wastewater. It mainly comes from petroleum refining, coal chemical industry, dyestuff, papermaking, pesticide, pharmaceutical and other production processes. It has the characteristics of large discharge, wide pollution and serious harm. Its toxicity will not only hinder the growth and reproduction of aquatic organisms, but also endanger human health. Phenolic compounds have long been listed by the US Environmental Protection Agency as one of the 129 priority monitoring pollutants. Phenol wastewater is also the focus of my country's water pollution control. Over the years, various treatment methods have been applied to the treatment of phenol wastewater. Among them, the adsorption method is the most commonly used and relatively efficient treatment...

Problems solved by technology

However, in the traditional biodegradation technology, most of the carrier materials that immobilize microorganisms themselves only play the role of a loading medium, and have no adsorption effect on phenol itself.
