Abstract

The invention discloses a static device for rapid purification of low-concentration lead-containing wastewater by utilizing a biomass material, and is characterized in that the static device includes a coarse filtration unit and a fine filtration unit; the coarse filtration unit is composed of a lower-part water pump and an upper-part coarse filter screen material box; the fine filtration unit is composed of a lower-part water outlet cavity, a middle fine filter screen material box and an upper-part water inlet cavity, wherein the water outlet cavity is externally provided with a water faucet; the water pump of the coarse filtration unit is connected to the water inlet cavity of the fine filtration unit. The static device can flexibly and conveniently adjust the material ratio of stirring materials, changes the particle volume through adjusting a rotating speed, and finds out the best adsorption rate of a local biomass material; through the inserting / withdrawing screen material boxes, efficient filtration, blocking delaying and convenient screen replacement can be achieved; and a series of efficient and economic treatment process parameters are quickly found out through an instrument, and necessary parameters are provided for a low-cost physical pollution control process.

Description

technical field [0001] The invention relates to equipment for exploring the treatment process of heavy metal lead pollution in the water environment, in particular to a static device for rapidly purifying low-concentration lead-containing sewage by using biomass materials. Background technique [0002] Soil, rivers, lakes and ponds in many urban and rural areas in China have lead pollution. Different from industrial pollution sources, the pollution in these areas is characterized by large pollution areas and low lead concentrations. It is necessary to explore a method and device that is more efficient than static filtration, adapts to local conditions, and is easy to operate to treat low-concentration lead-containing polluted water. [0003] There are many processes for treating high-concentration lead sewage at home and abroad, but due to their high cost and complicated processes, it is impossible to promote them in the vast urban and rural areas of our country. In Shangha...
