Leachate recharge well adopting biochar adsorbent as filler and preparation method of biochar adsorbent
The invention aims to provide a leachate recharge well adopting a biochar adsorbent as filler and a preparation method of the biochar adsorbent. The recharge well comprises a main body, wherein a garbage heap body is buried in the main body; a repair covering soil layer is arranged above the garbage heap body; a recharge floral tube ditch is arranged at the lower part of the garbage heap body; a recharge floral tube is arranged in the recharge floral tube ditch; and the filler of the recharge floral tube ditch is sludge biochar. The method comprises the following steps of: drying sludge at 105 DEG C for 24 hours or drying the sludge by a similar method; then carrying out pyrolysis treatment on the dried sludge in a nitrogen environment at a temperature not lower than 300 DEG C for at least 2 hours and then cooling. The leachate recharge well provided by the invention is simple in structure and convenient to use; the filler of the recharge floral tube ditch is the sludge biochar; the sludge biochar is rich in raw material, convenient to obtain, simple to manufacture, low in cost, environment-friendly and free of secondary pollution; compared with commercial activated carbon, the sludge biochar has similar or even better TOC removal efficiency and ammonia nitrogen removal efficiency.
本发明旨在提供一种采用生物炭吸附剂作为填料的渗滤液回灌井及该生物炭吸附剂制备方法，该回灌井包括主体，主体内填埋有垃圾堆体，垃圾堆体的上方为修复覆盖土层，垃圾堆体的下部设置有回灌花管管沟，回灌花管管沟内设置有回灌花管，回灌花管管沟的填料为污泥生物炭；该方法为将污泥在105℃下烘干24h，或以类似方法烘干；接着，将烘干后的污泥在氮气环境中于不低于300℃的温度下热解处理至少2小时后冷却。本发明结构简单、使用方便，回灌花管管沟的填料为污泥生物炭，污泥生物炭原料丰富、获取方便、制作简单、成本低、环保、不会产生二次污染，相对商用活性炭而言，具有相近甚至更优的TOC去除效率和氨氮去除效率。
