Abstract

The invention provides a preparation method of iron-carbon micro-electrolysis ceramsite filler for water treatment, which is characterized by comprising the following steps: 1, mixing iron scrap, waste circuit board powder, river sediment powder of loess cliff section of Xiaofu river in Zibo city of Shandong province and clay, the mass ratio is (15 to 20) to (55 to 60) to (10 to 15) to (10 to 15), and the mixture is formed; 2, adding the mixture into a granulating disc, additionally adding binder diluent for granulating, and the mass of the binder diluent is 25 to 30 percent, the spheroidal particles with each diameter of Phi 3 to 5 mm are prepared; 3, calcining and cooling under oxygen-free atmosphere after the spheroidal particles are dried, and obtaining the iron-carbon micro-electrolysis ceramsite filler. The iron-carbon micro-electrolysis ceramsite filler is prepared by solid waste such as waste iron scrap and waste circuit board powder as the main raw materials, the resources and energy are saved, using waste to treat waste and energy conservation and emission reduction are realized. The wastewater treatment effect is obviously superior to the existing ceramsite, especially for the iron-carbon micro-electrolysis reduction treatment effect of highly toxic wastewater containing hexavalent chromium; and the iron-carbon micro-electrolysis ceramsite filler is long in service life, simple in maintaining, and easy in utilization of regenerative cycle.

Description

technical field

[0001] The invention provides a preparation method of iron-carbon micro-electrolytic ceramsite filler for water treatment, which belongs to the technical field of waste water purification treatment materials and environmental material preparation, especially the purification treatment technical materials of highly toxic waste water and high concentration, refractory biodegradable organic waste water field. Background technique

[0002] Ceramic anti-hardening iron-carbon micro-electrolysis ceramsite can use iron-carbon micro-electrolysis technology to treat organic wastewater and heavy metal wastewater with high concentration, high chroma, high toxicity and refractory biodegradation. When the iron-carbon micro-electrolytic ceramsite is immersed in wastewater, due to the potential difference between iron and carbon, countless primary batteries will be formed in the wastewater. These tiny batteries use iron with a low potential as the cathode and carbon with a ...
