Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

Full-automatic coal-containing wastewater treatment device, as shown in fig. 1-2, has set gradually setting up setting tank 1, reaction box 3 and purifying box 4 according to handling the flow, is provided with impeller 12 in setting tank 1 to fully stir sewage, and the bottom is provided with detachable precipitate plate 2 in setting tank 1 to adsorb the flocculus, is provided with detachable MBR reactor 31 in reaction box 3 to filter the microorganism in the waste water.

The center of the inlet of the settling tank 1 is provided with a detachable filter plate 11, the filter plate 11 is provided with filter holes with equal density, waste water enters the settling tank 1 through the filter plate 11, large coal particles in the waste water stay on the filter plate 11, and when the number of the coal particles on the filter plate 11 is large, the filter plate 11 is detached and cleaned.

The impeller 12 has two at least, all sets up on the inner wall of setting tank 1, and setting tank 1 external power supply is for the power supply of impeller 12, and impeller 12 is the uniform velocity rotation that is slower, puts the flocculating agent after the ratio into setting tank 1, and impeller 12 rotates and makes waste water and flocculating agent fully contact, and the tiny particle coal in the waste water and heavy metal combine with the flocculating agent, form big flocculus.

Be provided with a plurality of gathering grooves 21 along level and vertical direction in the precipitate board 2, precipitate board 2 is the engineering plastics material, acid and alkali-resistance, corrosion-resistant, and the embedding is in the bottom of settling tank 1, and the flocculus gets into in gathering groove 21 under the action of gravity, obtains fixedly, no longer floats along with impeller 12's rotation, when filling up the flocculus in gathering groove 21, detachable gathering groove 21 off, wash the flocculus wherein, precipitate board 2 can use repeatedly.
