Porous ceramics provided with amorphous pore surfaces and methods for treating effluent and wastewater by the same ceramics

摘要

The present invention is directed to a method for treating effluent and wastewater of various kinds, which is currently a problem in its processing. For example, wastewater containing substantially non-removable phosphorus and organic chlorine compounds such as nitrogen, tetrachlorethylene and the like, excreta from feedlots containing high levels of organic nitrogen compounds, lead, hexavalent chromium, cadmium, and the like A wastewater containing heavy metals, a dewatering product plant containing a high level of water-soluble protein, a marine product processing plant, a sewage treatment plant, a sewage treatment plant effluent, a pulp mill effluent, a photographic development wastewater, To a method of treating by using a porous ceramic provided with an amorphous pore surface.;Porous ceramics provided with an amorphous pore surface can be produced by mixing the clay, pore forming material and water, shaping into any form, drying, heating of the dried product so that the product temperature from 600 to 800 Heating for 3 to 7 hours, and then calcining at 1,200 to 1,500 [deg.] C.
