Problems solved by technology

However, the organic pollutants in the water body contain a large number of macromolecular substances that are not easily absorbed and utilized by microorganisms, such as protein, fat, cellulose, etc. It is the existence of these macromolecular substances that greatly reduces the biodegradability of the water body.

Abstract

The invention discloses a complex enzyme preparation for repairing river, lake and landscape water. The complex enzyme preparation comprises the following components by weight percent: 30-40% of protease, 20-30% of cellulase, 10-20% of amylase, 10-20% of lipase, 5-15% of pectinase and 5-15% of laccase. In a use process, the complex enzyme preparation is prepared at a ratio, the solution thereof is added into to-be-treated water and the addition concentration is 1-5g / m<3>. The complex enzyme preparation can degrade the macromolecular organic pollutants which are difficult to be utilized by microorganisms in water; the activation of indigenous microorganisms can be stimulated and the growth and propagation of the microorganisms can be accelerated; and the combined oxygen is released and the re-oxygenation function of water is enhanced.

Description

technical field [0001] The application belongs to the technical field of environmental restoration, and more specifically, the application relates to a compound enzyme preparation for purifying river courses, lakes, and landscape water bodies, as well as its preparation method and application. Background technique [0002] Water is the basis for human survival and development. With the development of social economy and the improvement of people's living standards, the importance of water environment protection has become increasingly prominent. my country has started water pollution prevention and control planning for key river basins since the "Ninth Five-Year Plan" period. After nearly 20 years of treatment, while the water quality of major rivers has improved, the water quality of natural or artificially formed rivers, lakes, and landscape water bodies in cities has not yet improved. There are many black and smelly water bodies, and even the main rivers in the urban area a...
