Stacked overflow type sewage treatment equipment

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to modularly assembled stacked overflow sewage treatment equipment. Background technique [0002] With the development of the economy, the discharge of domestic sewage continues to increase, such as sewage discharged from landscape water and public toilets, leading to increasingly severe water pollution problems. [0003] Because sewage has the conditions for the growth and reproduction of microorganisms, microorganisms can obtain nutrients from sewage, and at the same time degrade and utilize harmful substances, thereby purifying sewage. Therefore, microorganisms can be widely used in sewage purification and treatment for the benefit of mankind. However, the sewage in the water needs to have enough filter materials to intercept the flow to facilitate the decomposition of microorganisms, and there must also be enough space for microorganisms to reproduce. However, in a limi...

Problems solved by technology

Therefore, microorganisms can be widely used in sewage purification and treatment for the benefit of mankind. However, the sewage in the water needs to have enough filter materials to intercept the flow to facilitate the decomposition of microorganisms, and there must also be enough space for microorganisms to reproduce. However, in a limited area Inside, the volume can only be increased by increasing the height. When the height is too high, the lateral pressure of the water will increase, and a sufficiently thick box is required for assembly. Too thick a box makes installation inconvenient. The structure of existing sewage treatment equipment Complicated, with high operating costs and low purification efficiency
