Embodiment 1

[0026] This embodiment relates to a production method of special modified mineral materials for black and odorous river courses, which consists of the following steps:

[0027] Step 1, drying the attapulgite clay, zeolite, and bentonite raw ore until the moisture content is 20%, then mixing them according to the weight ratio of 2:1:1, and coarsely crushing them into a particle mixture with a particle diameter of 4mm;

[0028] Step 2, adding calcium nitrate equivalent to 5% of the weight of the granular mixture and lanthanum chloride equivalent to 1% of the weight of the granular mixture into the granular mixture, and fully mixing to obtain mixed small particles;

[0029] Step 3, spraying water to the mixed small particles to adjust the water weight content to 32%, and extruding it into a sheet-like clay mixture with a pair of rollers and a three-roller with a distance of 1mm;

[0030] Step 4, mixing the flaky clay mixture with polyferric chloride and polyaluminum chloride acco...

Embodiment 2

[0033] This embodiment relates to a production method of special modified mineral materials for black and odorous river courses, which consists of the following steps:

[0035] Step 2, adding calcium nitrate equivalent to 5% of the weight of the granular mixture and lanthanum chloride equivalent to 1% of the weight of the granular mixture into the granular mixture, and fully mixing to obtain mixed small particles;

[0036] Step 3, spraying water to the mixed small particles to adjust the water weight content to 28%, and extruding into a flaky clay mixture with a pair of rollers and a three-roller with a distance of 2mm;

[0037] Step 4, mixing the flaky clay mixture with polyferric chloride and polyaluminum chloride accordin...

Embodiment 3

[0040] This embodiment relates to a production method of special modified mineral materials for black and odorous river courses, which consists of the following steps:

[0041] Step 1, drying the attapulgite clay, zeolite, and bentonite raw ore until the moisture content is 5%, then mixing them according to the weight ratio of 3:1:1, and coarsely crushing them into a particle mixture with a particle diameter of 3mm;

[0042] Step 2, adding calcium nitrate equivalent to 5% of the weight of the granular mixture and lanthanum chloride equivalent to 1% of the weight of the granular mixture into the granular mixture, and fully mixing to obtain mixed small particles;

[0043] Step 3, spraying water to the mixed small particles to adjust the water weight content to 30%, and extruding it into a sheet-like clay mixture with a pair of rollers and a three-roller with a distance of 1 mm;

Abstract

The invention relates to a method for producing special-purpose modified mineral materials for black-odor rivers, which comprises the following steps: step 1, attapulgite, zeolite and bentonite ores are dried, mixed and coarsely crushed; step 2, calcium nitrate and lanthanum chloride are added to mix and obtain hybrid particles; step 3, water is sprayed to extrude the hybrid particles to be flake clay mixture; step 4, the flake clay mixture is uniformly mixed with polyferric chloride and poly aluminum chloride; and step 5, the special-purpose modified mineral materials for the black-odor rivers are obtained by drying and grinding. The method for producing special-purpose modified mineral materials for black-odor rivers are easy to obtain raw mineral materials, is low in cost, obtains the special-purpose modified mineral materials for the black-odor rivers by optimizing a series of steps such as mixing, crushing, squeezing, drying and grinding and the like particularly by adding the calcium nitrate and the lanthanum chloride during the production process, achieves low cost purification treatment of the black-odor rivers, is simple in operation step and easy to control, and is suitable for large-scale applications in industry.

Description

technical field [0001] The invention relates to a production method of black and odorous river channel purification treatment materials, in particular to a production method of special modified mineral materials for black and odorous river channels. Background technique [0002] At present, most urban rivers in our country have evolved into black and smelly rivers. In many cities in our country, the organic pollution of rivers is ubiquitous and increasingly prominent. Urban sewage is directly discharged into rivers, and the rivers flowing through towns are seriously polluted. Therefore, it is of great significance to study the materials and methods used for the purification of black and odorous rivers. [0003] CN102603078A (published on July 25, 2012) discloses a method for water restoration of black and odorous rivers, which uses the joint action of bionic aquatic plants, biological oxygen enrichment and microbial preparations to build a bioaugmentation system for black a...
