Nanometer heavy-metal water purifying agent, preparation method and water purification unit

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...

Problems solved by technology

[0006] In order to make the relative movement between the particles and the water flow, the best way is to control the speed of the water flow. At present, most mixing reaction equipment has the problem of non-adjustable water flow and direction, which greatly reduces the number of particle collisions, so the flocculation effect is greatly reduced. It is easy to cause the loss of the amount of medicine; therefore, a large increase in the ratio of vortex in the mixing reaction equipment has always been the object of research by those skilled in the art
