Embodiment Construction

[0031] A preparation method of a nanoscale heavy metal water purifier, comprising the steps of:

[0032] 1. Use shells to remove residues on the surface of shells by hydrochloric acid with a weight ratio of 0.6%, and then calcine at a high temperature of 900°C for 20 minutes to remove organic impurities contained in shells, and then crush them to make nano-scale modified shell powder ;

[0033] 2. Select diatomite and add calcium carbonate to mix, and then the above-mentioned mixture is calcined at 900°C for 20 minutes and then pulverized to make nano-scale modified diatomite. The weight ratio of diatomite to calcium carbonate is 10:1 ;

[0034] 3. Select the loofah and cut it into small pieces, crush it with a pulverizer and sieve it. Mix the crushed loofah with 30% NaOH solution and absolute ethanol, alkalinize it at room temperature 25°C for 48 hours, and then use 700W microwave intermittently After irradiating for 10 minutes, reflux for 3 hours in a constant temperature ...

Abstract

The invention discloses a nanometer heavy-metal water purifying agent, a preparation method and a water purification unit. The nanometer heavy-metal water purifying agent is prepared by preparing a mixture of nanometer modified shell powder, nanometer modified diatomite, modified vegetable sponge of luffa, sodium aluminate and titanium dioxide at various temperatures through temperature control. The water purifying agent comprises, by weight, 30 to 50% of nanometer modified shell powder, 20 to 40% of nanometer modified diatomite, 10 to 30% of modified vegetable sponge of luffa, 5% of sodium aluminate and 5% of titanium dioxide. The water purification unit provided by the invention employs the nanometer heavy-metal water purifying agent and obtains a great amount of flocculating constituents by fully mixing sewage and the water purifying agent under multiple effects of a fluid radial vortex generating device, a fluid axial vortex generating device and a vortex generator, thereby realizing sewage purification.

Description

technical field [0001] The invention relates to a sewage treatment substance, a preparation method thereof, and water purification equipment, in particular to a nanoscale heavy metal water purification agent, a preparation method, and water purification equipment. Background technique [0002] Heavy metals have the characteristics of high toxicity, persistence, and refractory degradation of water bodies, which have attracted more and more attention from scholars at home and abroad. Heavy metals that enter water bodies through natural means generally do not cause pollution to water bodies, but due to human activities, a large number of pollutants containing heavy metals enter the water environment, which not only causes major economic losses, but also has a major impact on ecosystems and human health. . [0003] Heavy metal pollution in water mainly comes from two sources: natural sources and anthropogenic sources. Natural sources are mainly debris products of rock weatheri...
