A kind of straw carbon composite material and its preparation method and application

Abstract

The invention belongs to the technical field of purification treatment of breeding atmospheric environment, and in particular relates to a straw carbon composite material and its preparation method and application. Aiming at the deficiencies of the existing deodorization methods, the invention provides a straw carbon composite material and a preparation method thereof, which are applied to the deodorization of manure in aquaculture. The straw carbon composite material prepared by the present invention comprises the following components in mass percentage: straw carbon 65%-91%, chlorite 5%-20%, hypochlorite 3%-10%, surfactant 1% to 5%. It is obtained by forming a mixture of pulverized straw carbon, chlorite, hypochlorite and surfactant with water or ethanol, heating to a subcritical or supercritical state, and baking and drying under an inert gas atmosphere. The straw carbon composite material has the properties of adsorption and chemical deodorization at the same time, the raw material is easily obtained, the preparation is simple, the operation is easy, the residue is low, and the impact on the environment is small.

Description

A kind of straw carbon composite material and its preparation method and application technical field The invention belongs to the technical field of aquaculture atmospheric environment purification treatment, be specifically related to a kind of straw carbon composite material and its Preparation method and application. Background technique Along with the development of my country's large-scale breeding industry, the pollution problem that breeding farms bring to the surrounding environment is also more and more acute. out. The manure discharged by livestock and poultry is one of the main pollution sources causing environmental problems. Livestock and poultry excrement itself or in storage The volatile odor components released in the process include amines, sulfur-containing nitrogen compounds, etc. These harmful gases are dangerous It will reduce the immunity of livestock to diseases, increase the cost of breeding, and also affect the health of practitioners and ...
