Natural zeolite water treatment agent

Abstract

The invention discloses a natural zeolite water treatment agent, belonging to the technical field of multifunctional water treatment agents. The natural zeolite water treatment agent is not-toxic and harmless, does not cause secondary pollution and has remarkable removal effects on ammonia nitrogen, fluorine, phosphorus, radioactive cesium (137Cs) and strontium (90Sr), organic pollutants and heavy metals in water so as to be an ideal product for purifying domestic water, industrial wastewater, domestic wastewater, aquaculture water and water in rivers, lakes and wells. According to the technical scheme, the preparation method of the natural zeolite water treatment agent comprises the following steps: taking 70-85% of zeolite (NH4 and clinoptilolite with substitution amount of greater than 140ml/100g), crushing, grinding into powder, baking for activating, and modifying; taking 10-25% of activated carbon, crushing, grinding into powder, baking and modifying; fully mixing zeolite and activated carbon; then, adding 5% of a natural adhesive (calcium bentonite); and making spherical or cylindrical granules with the diameter of 1-10mm by adopting a conventional double-roller extruding granulation method or aggregating granulation method.

Description

Technical field: [0001] The invention belongs to the technical field of a multifunctional water treatment agent. Background technique: [0002] At present, there are two major problems in the "water" of countries in the world: one is the shortage of water resources, and the other is serious water pollution. In order to alleviate the severe water situation: first, water conservation is a priority, which is mainly reflected in controlling demand and creating a water-saving society; second, pollution control is the foundation; third, multi-channel open source, which mainly refers to the development of non-traditional water resources; [0003] Countries around the world are now turning to the development of non-traditional water resources. Non-traditional water resources include: rainwater, recycled sewage, seawater, and aerial water. At present, the reuse rate of industrial water in my country is only about 60%, and urban wastewater is rarely used. The reuse of urban waste w...

Problems solved by technology

[0002] At present, there are two major problems in the "water" of countries in the world: one is the shortage of water resources, and the other is serious water pollution.

Some of these methods are expensive to use, some have poor treatment effects, some have complex preparation processes, some have many residues, some sediments cannot be recycled, and even cause secondary pollution.
