Sludge carbon-based micro-electrolysis filler for improving biodegradability of chemical wastewater as well as preparation method and application of sludge carbon-based micro-electrolysis filler
The invention provides a sludge carbon-based micro-electrolysis filler for improving biodegradability of chemical wastewater as well as a preparation method and application of the sludge carbon-based micro-electrolysis filler, and belongs to the technical field of environmental engineering. The sludge carbon-based iron-carbon filler comprises the following raw materials in percentage by weight: 20-40 wt% of sludge carbon powder, 15-40 wt% of reduced iron powder, 0-25 wt% of a catalyst, 10-40 wt% of a binder and 2-5 wt% of a pore forming agent. The sludge carbon-based iron-carbon micro-electrolysis filler is simple in preparation method and easy for industrial production, the porous sintered micro-electrolysis filler can be prepared by uniformly mixing dehydrated and dried sludge with metals such as iron, copper and the like or metal oxides according to a ratio, extruding and forming into a regular shape and carrying out anaerobic sintering, and the sludge carbon-based iron-carbon micro-electrolysis filler is easy for large-scale production; according to the present invention, the material has characteristics of low cost and strong practicality, can efficiently achieve the sludge reduction and the material utilization, can effectively degrade 2-hexanol, aniline, p-isopropylaniline, 2, 6-di-tert-butylphenol, 2, 5-dinitrobenzoic acid, 3, 5-dimethyl-4-heptanone and other specific pollutants in the chemical industry wastewater, and is the material with characteristics of low price and strong practicality.
本发明提出了一种提高化工废水可生化性的污泥炭基微电解填料及其制备方法和应用，属于环境工程技术领域。污泥炭基铁碳填料，包括如下重量配比的原料：污泥炭粉末20~40wt%、还原铁粉15~40wt%、催化剂0~25wt%、粘结剂10~40wt%、造孔剂2~5wt%。该污泥炭基铁碳微电解填料不仅制备方法简单，易于工业化生产，只需将脱水干化污泥与铁、铜等等金属或金属氧化物按照比例混合均匀挤压成型为规则形状，通过无氧烧结可制备得到多孔烧结微电解，易于规模生产，高效实现污泥减量化与材料化利用，还能有效将化工废水中2‑己醇、苯胺、对异丙基苯胺、2,6‑二叔丁基苯酚、2,5‑二硝基苯甲酸、3,5‑二甲基‑4‑庚酮等特征污染物降解，是一种价格低廉、实用性强的材料。
