Embodiment 1

[0010] Example 1: Used in sewage treatment projects in living quarters

[0011] In the residential sewage treatment project, in the oxidation ditch at the outlet of a section of biological treatment, the amount of water purification agent added is 10% of the wastewater treatment volume, and the sewage is precipitated. After the above treatment, the water quality reaches the national first-level discharge. standard.

Embodiment 2

[0012] Embodiment 2: Used for the treatment of waste water in the middle stage of papermaking

[0013] The water purifying agent is added to the anaerobic and aerobic system of the wastewater treatment in the middle stage of papermaking. The amount of the water purifying agent added is 15% of the wastewater treatment capacity, and the sewage settles. After the above treatment, the water quality reaches the standard of reclaimed water, which can realize the Recycling of waste water.

Abstract

The invention relates to a diatomite water purifier which belongs to the technical field of environmental protection. The diatomite water purifier is formed by mixing diatomite and lignin, wherein the content of the diatom in the diatomite is larger than 80 percent, and the fineness of the diatomite is larger than 80 meshes. The weight percent of the diatomite is 70-80, and the weight percent of the lignin is 20-30. Compared with the prior art, the diatomite water purifier has the advantages of good purifying effect, wide application range, no secondary pollution, low cost and the like. The diatomite water purifier not only can be used for purifying low-concentration sewage, such as domestic sewage, and the like, but also can be used for purifying waste water in the process of paper making.

Description

Technical field: [0001] The invention relates to a diatomite water purifying agent, which belongs to the technical field of environmental protection. Background technique: [0002] Existing water purifiers used for sewage treatment have several kinds, all of which have certain effects. But there is still the problem of secondary pollution. [0003] Water pollution control has become the most emerging environmental protection industry today, and its annual output value has grown at a rate of more than 50%. The water pollution problems caused by human production and life have threatened the survival of human beings. With the smallest cost, there is no secondary pollution. It is the common cause of all mankind to solve the problem of water pollution, realize the recycling of water resources, and improve the utilization rate of water resources. [0004] Environmental protection is a basic national policy of our country. Energy conservation and emission reduction has become a h...
