Problems solved by technology

The physical method often treats the symptoms but not the root cause, and the aeration and reoxygenation technology and the sediment dredging technology all have the disadvantage of large investment, and do not have the ability to control pollution on a large scale, and the final treatment of the polluted sediment removed in the sediment dredging is also a problem. It is a difficult problem; the chemical method mainly uses various chemical agents, such as add

The compound water treatment agent provided by the invention has the advantages of low cost, large specific surface area, high activity, high dispersity and high treatment efficiency.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a composite water treatment agent, and also relates to a preparation method and application of the composite water treatment agent. Background technique [0002] At present, water pollution has become one of the most important problems of urban environment in our country. Rivers and lakes across the country are generally polluted to varying degrees, especially in the middle and lower reaches of large and medium-sized cities. Urban rivers are an important part of my country's water environment. Due to the discharge of industrial wastewater and urban domestic sewage, urban rivers are seriously polluted and eutrophication is common. According to statistics, by the beginning of the 20th century, there was almost no complete natural river in the world, and the severe damage and degradation of urban rivers has been recognized as a global ecological environment problem. It c...
