Embodiment 1

[0010] Mix aluminum sulfate with 22% by weight and the rest as medium-grade diatomite powder (60% diatom content) to form a water purifier, put it into 1000 times high chroma wastewater (such as printing and dyeing wastewater, etc.), and after 10 Minute flocculation and sedimentation effectively remove SS, COD, BOD, pigments, and heavy metals in the water, and the treated wastewater can be recycled or discharged up to standard.

Embodiment 2

[0012] Mix 13% by weight of ferric chloride and the rest with medium-grade diatomite powder (65% diatom content) to form a water purifier for drinking water purification, and add 2 / 10,000 of the original water weight Water purifier, after 2 minutes of flocculation and precipitation, it reaches the national drinking water standard.

Embodiment 3

[0014] Use 15% by weight of polyaluminum chloride and the rest to be medium-grade diatomite powder (65% diatom content) to form a water purifier for water treatment in fish ponds. Add water purifier, after 30 minutes of flocculation and precipitation, it can remove 90% of SS, COD, BOD, and 80% of TN and TP in water.

Abstract

The invention relates to a bergmeal water purification agent, which belongs to the water disposal technical fields. The water purification agent uses the medium-grade diatomite powder whose diatom content is between 60-70% as the basal body, combined with the adjuvant additive or polyacrylamide; wherein: a, the weight ratio of the component is: the adjuvant additive 13-22%, the rest is the medium-grade diatomite powder; the adjuvant additive is aluminum sulfate, ferric chloride, polychloride; b, the weight ratio of the component is: polyacrylamide 3-4ppm, the rest is the medium-grade diatomite powder.

Description

Technical field: [0001] The invention relates to a diatomite water purifying agent, which belongs to the technical field of water treatment. Background technique: [0002] At present, there are many products and methods for water treatment, all of which have certain effects. However, there are problems such as high cost or easy to cause secondary pollution. [0003] Through document search, do not find the public report identical with the present invention. Invention content: [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a diatomite water purifying agent with low cost and high purification efficiency. [0005] The water purifying agent of the present invention is formed by mixing mid-grade diatomite powder with a diatom content of 60-70% as a base, adding auxiliary additives or polyacrylamide; wherein: [0006] a. The percentage by weight of the components is: auxiliary additive 13-22%, the rest is medium-grad...
