Description

一种油污染土壤膨松剂及其制备方法
技术领域
本发明属于微生物领域，具体涉及一种油污染土壤膨松剂及其制备方法。
背景技术
随着石油工业的发展，在采油、炼油、运输与利用过程中，不可避免地造成石油废弃物对土壤的污染。油田的油污染是整个石油烃污染源总体中的重点。油田的油井、集输站、中转站、联合站等生产设施，由于各种原因，会把原油直接或间接地泄漏于地面，仅单井年产落地原油量可高达2吨。石油污染土壤中含有多种有害成分，如多环芳烃，酚类等对人及动物的毒性极大，甚至可能致癌。处理不当可造成地下水污染，其中的挥发性有机化合物还会造成空气污染。
油污染土壤的处理方法主要有3种：物理处理、化学处理和生物处理(生物修复)。其中微生物法是利用微生物自我调控机制以及对污染物的综合净化功能处理土壤中的石油类污染物，使它们在生物的新陈代谢循环中转化和去除。石油污染土壤微生物修复技术具有费用低、处理效果好、对环境影响低、无二次污染、不破坏植物生长所需要的土壤环境等优点，是石油污染土壤保护领域最具生命力的处理技术。
土壤颗粒具有一定的黏性，容易聚结成块状，从而导致土壤颗粒的孔隙率减小，不利于土壤中水分的保持及空气的流通，对微生物的生长和繁殖不利，从而严重制约了微生物处理的效果。
发明内容
为了改善油污染土壤理化性质，以提高后期微生物处理的效果，本发明提供一种油污染土壤膨松剂及其制备方法，其技术方案为：
以柚子皮干化物为主要成分的土壤膨松剂，包括柚子皮干化物，草木灰和磷酸二铵，各配料的质量百分比为：柚子皮干化物55～70％、草木灰10～25％、磷酸二铵5～20％。
土壤膨松剂的制备方法是将柚子皮干化物粉碎为0.2～2mm颗粒状，按照上述比例与草木灰和磷酸二铵混合均匀制成。
向油污染土壤中加入本发明研制的膨松剂，能够明显改善土壤结构，提高土壤的总体积，增加土壤有机质含量及孔隙率，有利于增强土壤中水分的保持及空气的流通，同时增加土壤钾、镁、氮、磷等营养元素，改善土壤理化性质，以提高后期微生物修复的效果。
具体实施方式
实施例1

柚子皮干化物粉末 55％
草木灰 25％
磷酸二铵 20％
实施例2

草木灰 25％
磷酸二铵 5％
实施例4
将柚子皮干化物粉碎为0.2mm颗粒状，与草木灰、磷酸二铵按照55∶25∶20的比例混合均匀，制备成的油污染土壤膨松剂，代号记为PS-01。
为了检验PS-01对油污染土壤的处理效果，利用未污染土壤配置了石油类含量为3％的油污染土壤，原油取自陕北延长油田定边采油厂，经四组分分析，其饱和烃含量65.08％，芳香分含量27.69％，胶质含量5.68％，沥青质含量1.55％。考查加与不加PS-01，土壤中微生物数量及呼吸强度，结果如下表1所示。
表1 加与不加PS-01的油污染土壤中微生物数量及呼吸强度
实施例5
将柚子皮干化物粉碎为2mm颗粒状，与草木灰、磷酸二铵按照70∶25∶5的比例混合均匀，制备成的油污染土壤膨松剂，代号记为PS-02。
为了检验PS-02对油污染土壤的处理效果，利用未污染土壤配置了石油类含量为5％的油污染土壤，考查加与不加PS-02，土壤中微生物数量及呼吸强度，结果如下表2所示。
表2 加与不加PS-02的油污染土壤中微生物数量及呼吸强度
