The invention discloses stacked overflow type
sewage treatment equipment which comprises a plurality of stacked cases. The stacked cases are assembled to form the stacked overflow type
sewage treatment equipment and comprise cases, first barriers, overflow plates,
settling tanks and
pollution discharge pipes, the first barriers and the overflow plates are longitudinally parallelly arranged on the inner walls of the cases, and one end of each
settling tank is fixedly connected with the corresponding overflow plate so that a cavity can be formed by each
settling tank and the corresponding case; the other end of each settling tank is connected with a side wall of the corresponding case, a water outlet is formed in the inner wall of each case, a plurality of
pollution discharge outlets are formed in joints of the settling tanks and the inner walls of the cases, and the
pollution discharge pipes are arranged on the outer sides of the cases and are communicated with the pollution discharge outlets. The stacked overflow type
sewage treatment equipment has the advantages that the quantities of the stacked cases can be set as needed, the stacked cases are assembled in a stacked manner, and accordingly the problem of excessively high side pressures can be solved; the stacked cases are connected with one another in a multilevel manner, accordingly, the lengths of
water flow channels can be increased, the total capacity can be increased, and overflow type merits can be effectively utilized by the stacked overflow type
sewage treatment equipment; the stacked cases of the stacked overflow type
sewage treatment equipment can be assembled as needed, the volume of the stacked overflow type
sewage treatment equipment can be voluntarily adjusted, and the stacked cases are convenient to assemble.
