Abstract

The invention provides an activated-carbon composite water treatment agent which is prepared from the following ingredients in parts by weight: 1-5 parts of albite, 1-5 parts of quartz, 20-35 parts of natural zeolite, 10-20 parts of attapulgite, 1-5 parts of sepiolite and 40-60 parts of activated carbon. The invention further provides a preparation method and use of the activated-carbon composite water treatment agent. According to the activated-carbon composite water treatment agent, raw materials mainly are a variety of natural ores and are abundant in source and low in cost, the preparation method is simple, and the eutrophication of water bodies can be effectively controlled through simultaneously controlling endogenous and exogenous pollutants of the water bodies. The water treatment agent is environment-friendly and can provide a good external environment for benthos of the water bodies.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to an activated carbon composite water treatment agent, a preparation method of the water treatment agent, and an application of the water treatment agent in preventing and controlling eutrophication of water bodies. Background technique [0002] Eutrophication of water body means that the water body accepts excessive nitrogen, phosphorus and other nutrients, causing abnormal reproduction of algae and other aquatic organisms in the water body, changes in water transparency and dissolved oxygen, resulting in deterioration of the water body, thus hindering the ecological environment and water function of the water body and destruction. The problem of water eutrophication has become a worldwide water pollution control problem, and it is also one of the global environmental problems. From a global perspective, 30% to 40% of lakes and reservoirs worldwide have suffered from eu...
