Problems solved by technology

However, the above-mentioned materials are non-porous biodegradable materials with relatively low porosity. When the above-mentioned materials are used as microbial carriers, the concentration of microorganisms attached to the carrier is usually very low, resulting in low sewage treatment efficiency and effluent water quality that cannot meet the requirements.

Abstract

The invention provides a microbial carrier. The microbial carrier is in a porous solid form and contains a biodegradation material with the weight content of 50% or more, the specific surface area is 100-900 m<2> / g, the average pore size is 20 nm-0.4 mm, the microbial carrier is at least of a two-layer structure, and the average pore size of the surface layer is 50 nm-0.4 mm. The microbial carrier can provide larger living environment for microorganisms, provide a carbon source for growth and propagation of microorganisms particularly denitrifying bacteria, improve the concentration of microorganisms in unit volume and improve the microbiological treatment efficiency.

Description

technical field [0001] The present invention relates to a microbial carrier. Background technique [0002] With the rapid development of industrial and agricultural production and the improvement of people's living standards, the amount of various industrial and agricultural production and domestic wastewater will also increase significantly. Most of these sewage are directly discharged into surface water bodies without any treatment. There are many pollution sources in urban areas, wide areas, and high intensity, which is very easy to pollute water resources. Even if local pollution occurs, it will be caused by the fluidity of water. Make the scope of pollution gradually expand. At present, less than half of the total discharge of industrial and urban sewage in my country has undergone centralized treatment, and most of the rest is directly discharged into rivers. There is little constraint on the discharge of sewage, which has led to the deterioration of a large number of...
