Embodiment 1

[0026] 1. Materials and methods

[0027] 1. Choose the best activated carbon material

[0028] Coal-based activated carbon has various pore sizes from micropores to macropores, so it has a good adsorption capacity for high-molecular organic matter. The adsorption capacity of activated carbon is not only related to its own properties, but also related to the molecular structure, solubility and ionization degree of the adsorbed substance. The purpose of the present invention is to use activated carbon to prepare a purifying agent to remove pollutants in livestock and poultry breeding sewage, and select coal-based activated carbon according to the properties of sewage components.

[0029] Fixing coal-based activated carbon into a certain shape is not only conducive to the adsorption and growth of microorganisms, but also facilitates the salvage treatment of activated carbon in the later stage. The activated carbon used in the present invention is as figure 1 Shown is a solid ...

example 1

[0069] Taking the original aquaculture anaerobic sewage in a static state as a control, put 1kg of sewage purifying agent into 100 L of aquaculture anaerobic sewage, and after 3.5 days of treatment, test the CODcr and BOD of the sewage 5 Index, calculate CODcr, BOD of sewage 5 Degradation rate, the specific results are shown in the table below.

Abstract

The invention relates to a sewage purifying agent, and particularly relates to a livestock and poultry breeding anaerobic wastewater purifying agent. The livestock and poultry breeding anaerobic wastewater purifying agent comprises composite microbial strains and an activated carbon carrier, wherein the activated carbon carrier is coal columnar activated carbon, and is solid columnar activated carbon which is prepared from 2-10-mesh coaly activated carbon in a sizing manner. The purifying agent has the characteristics of low cost, and efficient adsorption, is capable of efficiently degrading pollutants in the livestock and poultry breeding anaerobic wastewater, and is relatively simple in preparation process; and the obtained purifying agent has the characteristics of strong stability, high microbial activity, efficient adsorption and pollutant degradation, and is friendly to environment, and free of secondary pollution.

Description

technical field [0001] The invention relates to a sewage purifying agent, more specifically to an anaerobic sewage purifying agent for livestock and poultry breeding. Background technique [0002] Activated carbon is an amorphous carbon made from biological organic matter through carbonization, activation and other processes. Activated carbon can be prepared from most carbonaceous materials such as wood, bamboo, coal, fruit shells, municipal waste and other wastes. [0003] Activated carbon has a huge specific surface area (500-1000m 2 ·gram -1 ), developed pore structure, unique surface active functional groups and stable chemical properties, can withstand acid and alkali, can withstand water stains, high temperature, high pressure, is an excellent adsorbent, can adsorb gas on its surface, For liquid or colloidal solids, for gases and liquids, the quality of the adsorbed substances can be close to the quality of activated carbon itself, but there are also problems such a...
