Embodiment Construction

[0015] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, which may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0016] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0017] refer to Figure 1~2 , the present invention relates to a biofilm based on graphene stack filler, which consists of six parts, namely graphene stack 1, aerobic layer 2, facultative aerobic layer 3, anaerobic layer 4, attached water Layer 5, flowing water layer 6. The biofilm adheres to the surface of the graphene stack and contacts with the sewage flow, filters out pollutants, and purifies the sewage. The biofilm falls ...

Abstract

Urban sewage and industrial sewage are main causes of water pollution, and more than 80% of the sewage in the world has not been treated effectively, which causes severe damages to security of water for human and a water ecological environment, so that how to removing harmful substances in the sewage and turning waste into wealth through a well-adapted sewage treatment means is a common subject that faced by the current society and urgently needing to be solved. A biofilm sewage treatment technology being a result of a sewage soil-filtering theory has been applied for many years, but selection of biofilm formation packing is still a bottleneck problem that affects the efficiency of biofilm filtering via the laminated packing. The laminated graphene packing based biofilm sewage treating method has the advantages that nitrogen elements, phosphorus elements and the like in the sewage can be removed, an eutrophic water body problem is solved, and compared with normal biofilm formation packing, the laminated graphene packing is simple to prepare, low in cost and easy to recycle and has important values in environmental protection application and a theoretical aspect.

Description

technical field [0001] The invention relates to a biofilm sewage treatment method based on graphene laminated packing, and belongs to the technical field of environmental engineering and the field of carbon materials. Background technique [0002] Urban domestic sewage and industrial sewage are the main causes of water pollution. More than 80% of the world's wastewater has not been effectively treated, leading to serious damage to human water safety and water ecological environment. Therefore, how to remove harmful substances in wastewater and turn waste into benefits through sewage treatment means is a common issue that the current society faces urgently to be solved. Biofilm sewage treatment technology has important application value in the control of point source pollution and non-point source pollution due to its advantages of simple production process and high decontamination efficiency. The biofilm method is mainly a technical means to use the biological bacteria atta...
