Nutrient slow-release type drinking water purifier and preparation method

Abstract

The invention provides a preparation method for a nutrient slow-release type drinking water purifier. The method comprises the steps: smashing palygorskite clay raw ore and dispersing into citric acid solution, stirring for 12-24 hours, filtering, drying, crushing, adding a plus hole agent, an antibacterial agent and nutrient elements, selenium and zinc, grinding for 0.2-0.5 hour in a high-speed ball mill, granulating in a granulator, rolling into a rotary kiln, and calcining for 0.5-1 hour at 400-500 DEG C to obtain the nutrient slow-release type drinking water purifier. Experiments show that after being treated by the nutrient slow-release type drinking water purifier, the drinking water has the pH value of 7.35-7.45, the potassium ion content is between 0.4 mg / L-0.55 mg / L stably, the zinc ion content is between 0.1 mg / L-0.25 mg / L stably, the iodine content is between 0.02 mg / L-0.1 mg / L stably, the selenium content is between 0.002-0.005 mg / L stably, and water becomes nutritional weak alkaline water, is in full compliance with national GBGB5749-2006 drinking water quality requirements, and also accords with national health drinking water quality standards.

Description

technical field [0001] The invention belongs to the technical field of water treatment and relates to a water purifying agent, in particular to a nutrient slow-release drinking water purifying agent. Background technique [0002] In recent years, with the development of industry and agriculture, the production and domestic wastewater of various organic chemicals, pharmaceutical wastewater, and agricultural wastewater (containing a large amount of pesticides, insecticides and herbicides) has not been treated up to the standard, but has been discharged. and groundwater have caused great harm, and the quality of drinking water sources has declined extremely. [0003] If heavy metal ions in drinking water exceed the standard: heavy metals cannot be decomposed in water, and the toxicity will be amplified after drinking, and will combine with other toxins in the water to form more toxic harmful substances. Heavy metals can cause headaches, dizziness, insomnia, joint pain, stones,...
