Recycling structure for treating sewage produced by spraying

Abstract

The invention provides a recycling structure for treating spraying output sewage, which comprises a box body, and the interior of the box body is divided into a filtering area and a recycling area by a partition plate; a first filter plate is mounted at the top of the filter area, a separator is arranged below the first filter plate, the interior of the separator is divided into a first filter cavity, a second filter cavity and a third filter cavity, and the first filter cavity is communicated with the filter area through the second filter plate; the first filter cavity is communicated with the second filter cavity through a third filter plate, and the second filter cavity is communicated with the third filter cavity through a fourth filter plate; the top of the third filter cavity is communicated with the recovery area through an overflow pipe, and a supernatant extraction mechanism is arranged at the top of the recovery area; a plurality of discharge pipes are arranged on the side wall of the box body and are used for discharging sediments and recyclable water; the spraying sewage can be subjected to multi-stage filtration, precipitated waste residues and particles are removed, and recycling and cyclic utilization are facilitated; supernatant of sewage after multi-stage filtration can be removed, and floating paint is prevented from entering circulating water supply.

Description

technical field [0001] The invention relates to the field of sewage treatment, and more specifically, relates to a structure for recycling sewage produced by spraying. Background technique [0002] Although the spraying treatment can play the role of anti-oxidation, moisture-proof and anti-corrosion, in the spraying process, the spray paint mist and organic solvent waste gas are absorbed by water to produce spraying wastewater. The wastewater is mixed with a large amount of waste residue and paint. If it is directly discharged It will cause pollution to the external environment, and it will also cause waste of water, resulting in an increase in cost; if the wastewater is recycled after treatment, most of them currently rely on simple filtration structures, which have poor filtration effects and affect work efficiency. Improve. Contents of the invention [0003] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention i...
