Description

1. Technical field

[0001] The invention belongs to the filter material manufacturing technology in the technical field of waste water and sewage treatment. 2. Background technology

[0002] With the improvement of industrial and agricultural production and people's living standards, the discharge of industrial sewage and domestic sewage in my country is increasing, and the total discharge of domestic sewage has exceeded the discharge of industrial sewage. According to the statistics of 2005, the domestic The total discharge of sewage is 28.14 billion tons, and the total discharge of industrial sewage is 24.31 billion tons.

[0003] The pollution sources in domestic sewage are mainly organic matter, phosphorus, nitrogen, etc., which have become the leading factors of eutrophication in rivers and lakes. With the development of the economy, the amount of sewage will increase. If it is not treated, it will be difficult to achieve the goal of environmental governance to build a b...
