Problems solved by technology

[0003] However, due to the high adsorption cost of a single activated carbon and the complex components of wastewater, including industrial wastewater, printing and dyeing, domestic sewage, and aquaculture wastewater, in actual wastewater treatment, the pollution components faced are relatively complex. Using a single graphene or activated carbon The effect of wastewater treatment agent as the main component needs to be improved

Abstract

The invention discloses a wastewater treatment agent and a preparation method and application thereof. The invention belongs to the technical field of environmental protection. The wastewater treatment agent comprises the following raw materials: a graphene adsorbent, activated carbon, a surfactant and corncobs, wherein the graphene adsorbent comprises carboxylated graphene oxide and a carbonyl iron graphene oxide compound. According to the prepared wastewater treatment agent, graphene is modified, activated carbon, corncobs and a proper amount of surfactant are compounded, the agglomeration phenomenon of the wastewater treatment agent is reduced, meanwhile, the flocculability of heavy metals, printing and dyeing fertilizers and the like in complex wastewater can be improved, and the removal effect is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a waste water treatment agent and its preparation method and application. Background technique [0002] At present, with the development of industry, the problem of water pollution is more serious. The methods of water pollution control include different methods such as physical, chemical and biological treatment, each with its own advantages and disadvantages. Among them, the use of adsorbents to adsorb and remove pollutants is relatively mature. method. [0003] However, due to the high adsorption cost of a single activated carbon and the complex components of wastewater, including industrial wastewater, printing and dyeing, domestic sewage, and aquaculture wastewater, in actual wastewater treatment, the pollution components faced are relatively complex. Using a single graphene or activated carbon The effect of the wastewater treatment agent as the main compon...
