Abstract

The invention discloses an activated carbon composite material for sewage treatment and a preparation method thereof. The activated carbon composite material for sewage treatment comprises the following components in parts by weight: 30-50 parts of modified activated carbon; 30-50 parts of diatomite; 10-20 parts of bamboo carbon; 10-20 parts of macro-porous adsorption resin; and 5-10 parts of chitosan. The activated carbon composite material for sewage treatment has adsorption effects on various organic substances and various heavy metal elements.

Description

technical field [0001] The invention relates to the technical field of sewage treatment materials, in particular to an activated carbon composite material for sewage treatment and a preparation method thereof. Background technique [0002] Sewage, also known as wastewater, usually includes domestic sewage, industrial wastewater, especially industrial wastewater, which is known as one of the three major public hazards in nature. Industrial wastewater usually contains organic matter and heavy metal elements, which directly flow into rivers and lakes, causing the death or even extinction of aquatic animals and plants; industrial wastewater can also seep into groundwater, if the surrounding residents use polluted surface water or groundwater as domestic water, It will endanger the health and cause death in severe cases. [0003] Activated carbon is prepared by pyrolysis and activation of carbon-containing raw materials such as wood, coal and petroleum coke. It has a developed p...
