A new sewage treatment sedimentation device

Abstract

The invention discloses a novel sewage treatment and precipitation device. The novel sewage treatment and precipitation device comprises a precipitation tank, wherein a water inlet pipe is arranged ata part, close to the middle position of the top, at the left side of the precipitation tank; a water outlet pipe is arranged at a part, close to the position of the bottom, at the right side of the precipitation tank; a chemical agent inlet pipe for adding a chemical agent is arranged at the middle position of the top of the precipitation tank; an end cover is detachably arranged at the top of the chemical agent inlet pipe; an observation opening, which is communicated with the inner part of the precipitation tank, is arranged at a part, close to the position of the front end, of the top of the precipitation tank; a cover plate, which is in rotatable match and connection with the precipitation tank, is arranged at the rear side of an opening part of the observation opening through a firsthinging shaft. The device disclosed by the invention has a relatively simple whole structure and relatively low production cost; the precipitation effect of sediment in sewage is obvious and the sediment and floating matters in the sewage can be effectively removed, so that the novel sewage treatment and precipitation device is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a novel sewage treatment and sedimentation device. Background technique [0002] At present, before sewage treatment, sedimentation in sewage sedimentation tanks is required to remove floating and sedimentable substances in sewage. However, the efficiency of sewage purification in existing sewage sedimentation tanks is low, and the sedimentation effect is not ideal. The link increases the difficulty. When the amount of sewage treatment is large, the floating and sedimentable substances in the sewage are washed into the next-level treatment pool by the turbulent water before they are completely settled. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel sewage treatment and sedimentation device, which can solve the above-mentioned problems in the prior art. [0004] In order to solve the above problems, th...
