Abstract

The invention provides a device for effective dephosphorization of dispersive sewage treatment equipment. The device comprises a water inlet, a preparation region and a work region, wherein the preparation region comprises a fixing cavity, a heating cavity and a sub transmission pipeline; the mixing cavity comprises a supplementing passage, a first water outlet and a first rotating shaft; the heating cavity comprises a first connecting opening, a second rotating shaft, a second water outlet and a heating plate; a work cavity comprises a third rotating shaft, a fourth rotating shaft, a rotatingframe and a separation plate; the upper half cavity of the work cavity is provided with a ring sleeve; lime milk is laid on the inner side wall of the sleeve ring; the outer profile dimension of therotating frame is identical to the inner wall dimension of the work cavity; a groove is formed in the side wall of the rotating frame; the groove penetrates through the rotating frame; the groove spirally ascends; crystallization beds are arranged at the upper and lower sides of the groove; the fourth rotating shaft is provided with a stirring blade; the stirring blade is provided with a water pulling sheet. The centrifugation effect is used; the increase of the corresponding ion concentration in the region is caused by tiny dissolution of insoluble subjects, so that precipitates are formed; the dephosphorization efficiency is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a device for effective phosphorus removal of distributed sewage treatment equipment. Background technique [0002] Sewage treatment is the process of removing impurities from sewage. The goal of sewage treatment is to generate a stream of treated sewage suitable for discharge back into the environment. Wastewater treatment may include primary, secondary and / or tertiary treatment. Primary treatment may include the use of septic tanks to separate solids, fats, oils, grease and generate primary treated effluent. The secondary treatment can be used to substantially degrade the impurities contained in the sewage after the primary treatment, and can especially include the functions of biochemical oxygen demand and total suspended solids removal and reduction. Tertiary treatment is often used to remove phosphorus and nitrogen containing impurities. [0003] Nowadays, for sewage phosp...
