Advanced ozone oxidation technology involved in coking deodorization in wastewater treatment includes O3/H2O2 technology and catalytic ozone oxidation technology.The O3/H2O2 technology was used to treat the biochemical effluent of coking wastewater in coking plant.Membrane separation technologies such as UF, NF and RO are mainly used to realize water reuse.RO is mainly used to remove inorganic substances, so it is used as the last procedure when water coking deodorization is reused.Other technologies are mostly used to remove organic matter without obvious removal effect on inorganic matter, which can be used as a pretreatment process for water coking deodorization and reuse.

Graphene is a two-dimensional periodic honeycomb lattice structure composed of six-membered carbon rings. Its thickness is only 1 carbon atom high, and it is the basic unit of other carbon nanomaterials.It can be rolled into zero-dimensional fullerenes (C60), rolled into one-dimensional carbon nanotubes (CNTs), or stacked into three-dimensional graphite.Graphene has a very large specific surface area and is an ideal pore free adsorbent for coking deodorization.At present, the application of graphene and its composites in water treatment has been gradually carried out.

Coking deodorant plant deodorant is not subject to temperature and other climatic environment constraints, will not be affected by temperature and the environment so that it can not play an effect.Plant type deodorant can be used for perennial, continuous coking deodorant treatment, can also be easy to deal with temporary, ultra-high concentration of coking deodorant.Plant deodorant itself to the human body, animals and plants and soil without any harm, odor molecular decomposition products are also completely harmless to the human body, animals, plants.

Coking of deodorization process in the actual application of the depth of coking wastewater treatment, is one of the main direction of the future development, also has its place in the depth of the coking wastewater treatment, the majority of coking depth of deodorization treatment technology used in the depth of the coking wastewater treatment effect is obvious, but the technology is immature, investment and high processing cost, used in practical engineering there are many difficulties, so to carry out the low cost high efficiency for the practical application of advanced treatment technology research is still a focus in the future.
