Embodiment 1

[0015] Embodiment 1: at first get raw material: ore such as attapulgite, bentonite, natural zeolite, carry out ore dressing purification: the ore containing attapulgite, montmorillonite and zeolite high attapulgite clay, bentonite and natural zeolite ore are left, put The gangues of non-attapulgite clay, non-bentonite and non-zeolite were detected, so that their contents were all above 70%. Then prepare a solution containing (by weight percentage) 8% sulfuric acid and spray it on the attapulgite and bentonite, stir evenly, and age for 8 hours to become activated attapulgite clay and activated bentonite. Roll the activated attapulgite clay and the activated bentonite to rollers twice respectively, and the thickness of the pressed sheet is about 1mm; to activate them again. Put the secondary activated attapulgite clay and activated bentonite into a drying roaster or a rotary kiln for drying and roasting at temperatures of 100-250°C and 100-350°C respectively; for 1-2 hours, acti...

Embodiment 2

[0016] Embodiment 2: Get raw materials: ores such as attapulgite, bentonite, natural zeolite, carry out ore dressing purification: leave the ore containing attapulgite, montmorillonite and zeolite high, and put non-attapulgite clay, non-bentonite and non-zeolite The gangues are detected, so that their content respectively reaches more than 70%. Prepare (by weight percentage) 9% sulfuric acid solution, spray on attapulgite and bentonite, stir evenly, and age for 6 hours to become activated attapulgite clay and activated bentonite. The activated attapulgite clay and the activated bentonite are respectively rolled twice on rollers, and the thickness of the pressed sheet is about 1.5mm, so that they are activated again. Put the activated attapulgite clay and activated bentonite in a drying and roasting furnace or a rotary kiln for drying and roasting at temperatures of 100-250°C and 100-350°C respectively; for 1-2 hours, activate them three times. Activation and modification of z...

Embodiment 3

[0017] Embodiment 3: get raw material: ore such as attapulgite, bentonite, natural zeolite, carry out ore dressing purification: leave the ore containing attapulgite, montmorillonite and zeolite high, put non-attapulgite clay, non-bentonite and non-zeolite The gangues are detected, so that their content respectively reaches more than 70%. Prepare a solution containing (by weight percentage) 10% sulfuric acid, spray it on attapulgite and bentonite, stir evenly, and age for 4 hours to become activated attapulgite clay and activated bentonite. The activated attapulgite clay and the activated bentonite are respectively rolled twice to the rollers, and the thickness of the pressed sheet is about 1-2mm; to activate them again. Put the activated attapulgite clay and activated bentonite in a drying and roasting furnace or a rotary kiln for drying and roasting at temperatures of 100-250°C and 100-350°C respectively; for 1-2 hours, activate them three times.

Abstract

The invention relates to an attapulgite clay composite cyanobacteria-eutrophication water treatment agent, which is a special sewage treatment agent in the fields of environmental protection and environmental treatment. According to the present invention, attapulgite clay, bentonite and natural zeolite are subjected to activation and modification and other high-tech deep processing, and are scientifically compounded with organic reagents to prepare the attapulgite clay composite cyanobacteria-eutrophication water treatment agent, which centralizes special properties of a plurality of minerals and organic additives; the treatment agent is mainly used for cyanobacteria outbreak emergency treatments of lakes, reservoirs, rivers, landscape water and the like, and eutrophication long-term treatments; the treatment agent is an innovative method for ecological restoration and resource; the treatment agent further can be used for heavy metal contaminated water treatments, wherein the heavy metals comprise arsenic, lead and the like; the treatment agent is adopted in the cyanobacteria outbreak in Tai lake of Jiangsu, Chao lake of Anhui and the like, cyanobacteria-eutrophication water multiple sampling and field treatment tests, the results show that: the treatment agent has characteristics of good treatment effect, convenient operation and low cost; the treatment agent can be adopted as the emergency agent and the long-term agent, and can treat both manifestation and root cause; the pumped sludge can be adopted as high-quality green fertilizer, such that the waste is changed into wealth so as to realize the ecological restoration and the resource recycling economy.

Description

technical field [0001] The invention relates to a treatment agent for sewage treatment and environmental treatment, in particular to a treatment agent made of attapulgite clay (referred to as attapulgite, the same below), bentonite, zeolite and organic reagent additives through high-tech, deep processing and scientific compounding. The preparation technology and application method of the composite high-efficiency cyanobacteria-eutrophic water treatment agent. Background technique [0002] Cyanobacteria blooms mainly occur in still water bodies, such as lakes, reservoirs, rivers, landscape water, etc., due to nitrogen and phosphorus eutrophication, under suitable climatic conditions. Specifically, industrial pollutants, agricultural fertilization and domestic waste discharge are the root causes of serious water pollution. Cyanobacteria in this severe eutrophication polluted water environment, breed under suitable climate (temperature above 30 ℃) conditions, develop quickly a...
