Description

Rotary decanter

Technical Field

The invention belongs to the technical field of sewage treatment equipment, and particularly relates to a rotary decanter and a construction method.

Background

The sewage treatment process is an effective process method for various economic, reasonable, scientific and industrial waste water of urban domestic sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like. The urban sewage treatment process is preferably determined after comprehensive technological and economic comparison according to the treatment scale, the water quality characteristics, the environmental function of the receiving water body and the local actual conditions and requirements. In the link of sewage treatment process, it is essential to decant water by using a decanter, which is also called a decanter and is one of the most critical mechanical devices in the SBR process. Can be divided into a siphon decanter, a rotary decanter, a self-floating decanter and a mechanical decanter, and is widely applied to China as a rotary decanter (belonging to one of mechanical decanters). The decanter is a device for periodically removing clear water adopted by SBR technology, and has the function of decanting the clear water from the surface of a static tank without stirring and precipitating to ensure the quality of the discharged water. The SBR process adopts intermittent reaction, water inlet, reaction, sedimentation and drainage are completed in the same tank, and a secondary sedimentation tank and sludge backflow equipment are not needed, so that the SBR process has the advantages of small occupied area, low investment, high efficiency, good effluent quality and the like; meanwhile, a plurality of SBR pools are connected, so that the sludge process can have the continuity (continuous water inflow) of the traditional sludge process and the intermittence of the typical SBR process, and is suitable for the requirements of large water quality, water quantity and change, thereby being widely applied at home and abroad. The existing water decanter adopts a transmission mechanism which is mostly in a single hanging point type, so that the stress of the water decanter body is too concentrated, the equipment is easy to crack, and mud is easy to leak between the connecting piece and the water decanter body.

A novel water decanter (application No. CN201720577967.5, publication No. CN 207002377U) of Chinese patent adopts the water decanter owner who installs on the bottom of the pool base, and the water decanter owner both ends are swing joint respectively has rotatable drain pipe, and the water decanter owner goes up the interval and is equipped with a plurality of water decanter branch pipes, a plurality of be equipped with the tie-beam on the water decanter branch pipe, and the cell body upper end is equipped with the support, and articulated on the support have electric putter, and electric putter's front end and tie-beam are articulated to be connected, and the upper end of a plurality of water decanter branch pipes is equipped with strains the basin, strains the articulated water frame of water basin both ends, strains the water frame front side and is equipped with the flotation pontoon that is located before. The technical scheme prevents impurities in the water tank body from entering the next working procedure, but the scheme has poor impurity prevention effect on one hand, only adds the connecting beam for reinforcing the structure, not only does not increase the strength enough, but also further reduces the flexibility, does not substantially solve the problem that the water decanter body and the connecting piece are easy to deform but difficult to maintain due to concentrated stress, has hidden danger in actual construction operation and needs to be improved.
