Petroleum sludge terminal treatment method
The invention discloses a petroleum sludge terminal treatment method, and relates to the technical field of petroleum sludge treatment. The method comprises the following steps: S1, performing deoiling pretreatment on the petroleum sludge: performing deoiling pretreatment on the petroleum sludge by using 6-12% of sodium gluconate, trisodium citrate or L-arginine; s2, carrying out electrochemical treatment on the washed oil stain water: by taking Fe3O4, Fe-C and Al-Fe nano materials as catalysts, decomposing organic matters in the oil-containing sewage generated in the treatment process in the S1 through an electrolysis process; and S3, carrying out solidification/stabilization treatment on the deoiled sludge. The method comprises the following steps: washing petroleum sludge with a chemical agent, carrying out liquid-solid separation, and carrying out organic matter degradation on the liquid through electrochemistry; the separated solid sludge is solidified by magnesium oxychloride cement to form products such as road bricks, and in the process, solid waste coal gangue and fly ash are used as admixtures, a water glass solution is used for replacing water, and the magnesium oxychloride cement which is fast in solidification and good in air hardness is used as a curing agent, so that green treatment of the petroleum sludge is realized.
本发明公开了一种石油污泥终端处置方法，涉及石油污泥处理技术领域。本发明包括如下步骤：S1.石油污泥脱油预处理：使用6％‑12％的葡萄糖酸钠、柠檬酸三钠或L‑精氨酸，对石油污泥进行脱油预处理；S2.洗油污水电化学处理：以Fe3O4、Fe‑C、Al‑Fe纳米材料作为催化剂，通过电解过程将S1处理过程中产生的含油污水中的有机物进行分解；S3.脱油污泥固化/稳定化处理。本发明首先以化学药剂洗涤石油污泥，液‑固分离以后，液体以电化学进行有机物降解；分离出的固体污泥以氯氧镁水泥进行固化，形成路砖之类的产品，该过程中以固废煤矸石、粉煤灰作为掺料，以水玻璃溶液替代水，以固化快、气硬性好的氯氧镁水泥作为固化剂，从而实现石油污泥的绿色治理。
