Abstract

The invention discloses a natural settling tank for efficiently removing lead and zinc. The natural settling tank comprises: a tank body; a flow equalizing plate arranged in the middle of the tank body and dividing the tank body into an upper part and a lower part; a liquid inlet formed below the flow equalizing plate; a first inclined plate and a second inclined plate arranged at the lower part of the tank body and forming a trapezoidal tank with the bottom of the tank body, wherein the liquid inlet is positioned above the trapezoidal tank; a residue outlet formed in the bottom of the tank body and communicated with the trapezoidal tank; a partition plate arranged at the upper part of the tank body; a baffle arranged at the upper part of the tank body and forming a tank with an opening with the partition plate, wherein the tank with the opening is communicated with the lower part of the tank body through the opening; an inclined tube sedimentation device arranged in the tank with theopening; and a residue discharge port arranged at the upper part of the tank body and communicated with the tank with the opening. According to the natural settling tank capable of efficiently removing lead and zinc, by arranging the inclined plate and the inclined tube, the treatment capacity is high, solid-liquid separation can be effectively carried out, and the lead and zinc removal effect isgood through three separations.

Description

technical field [0001] The invention relates to the technical field of settling tanks, in particular to a natural settling tank with high efficiency for removing lead and zinc. Background technique [0002] In order to realize the disposal of waste acid and pickling sludge in the metal surface treatment industry, after a series of reactions such as acid-base neutralization and redox, the heavy metal ions in the waste acid sludge are separated to obtain ferrous chloride flocculant products. This technology can not only realize the comprehensive utilization of solid waste in the regional steel wire rope industry, effectively solve the problem of regional pickling sludge and waste acid disposal, but also realize the recycling of solid waste resources, which can provide strong support for local economic and environmental development , with good environmental and social benefits; the project has zero discharge of process wastewater, and the ground flushing water and initial rainw...
