Method for treating sludge and method for preparing environment-friendly bricks from obtained solid waste sludge
The invention discloses a method for treating sludge. The method comprises the following steps: (1) mixing citric acid, urea and boric acid, heating and reacting to prepare boron-nitrogen co-doped graphene nanoparticles; (2) sequentially dropwise adding the solution prepared from the boron-nitrogen co-doped graphene nanoparticles, a biological enzyme solution and the dispersion liquid to the surface of an anode substrate to prepare a biological anode loaded with the boron-nitrogen co-doped graphene nanoparticles; (3) the biological anode, a proton exchange membrane and a cathode form a battery containing an anode chamber and a cathode chamber; and (4) putting the sludge into an anode chamber of the battery for degradation. The invention also discloses a method for preparing the environment-friendly brick by using the sludge treated by the biological battery. In addition, the invention also discloses a biological battery for treating sludge, and the battery comprises a shell, an anode chamber, a proton exchange membrane, a cathode chamber and an external closed loop. The method provided by the invention can effectively realize waste reutilization, and can bring good economic benefits.
本发明公开了一种处理污泥的方法，包括如下步骤：(1)将柠檬酸，尿素和硼酸混合后加热反应制得硼氮共掺杂石墨烯纳米颗粒；(2)依次将硼氮共掺杂石墨烯纳米颗粒制成的溶液、生物酶溶液和分散液滴加到阳极基片表面制得硼氮共掺杂石墨烯纳米颗粒负载的生物阳极；(3)将生物阳极与质子交换膜和阴极一起组成含有阳极室和阴极室的电池；(4)将污泥放入到电池的阳极室中进行降解即可。本发明还公开了一种使用生物电池处理过的污泥制备环保砖的方法。此外，本发明还公开了一种处理污泥的生物电池，所述电池包括外壳，阳极室，质子交换膜，阴极室及外部闭合回路。本发明所提供的方法可以有效地实现废物再次利用，能够带来良好的经济效益。
