Abstract

The invention provides a back-flushing cutting module for a ceramic bio-filter and a three-dimensional back-flushing technology of the back-flushing cutting module. The adopted three-dimensional back-flushing technology is realized mainly by depending on the back-flushing cutting module. The back-flushing cutting module for a ceramic bio-filter comprises a cutting framework, a cutting skeleton, asecond back-flushing water inlet pipe, a second back-flushing water inlet branch pipe, a rotating shaft, a frame plate and a transmission motor, wherein the transmission motor drives the back-flushingcutting module to perform transverse filter material cutting through horizontal rotation of the rotating shaft; and the ceramic bio-filter performs longitudinal back-flushing upwards through back-flushing water which enters through a first back-flushing water inlet pipe. The three-dimensional back-flushing technology adopting three process of a 'independent gas back-flushing mode' to a 'gas-watercombined back-flushing mode' to a 'dependent water three-dimensional back-flushing mode' is provided, so that sufficient friction and movement of a filter material on a longitudinal face and a transverse face are performed, and accordingly, the bio-filter is radically prevented from blockage and caking of the filter material.

Description

technical field [0001] The invention relates to a backwashing technology for a ceramsite biological filter, and more specifically relates to a three-dimensional backwashing technology for a ceramsite filter biological filter equipped with a backwashing cutting module. Background technique [0002] Biological filter technology has the advantages of high load, small footprint, high degree of automation, and impact load resistance, and is favored by the majority of water treatment practitioners. With the continuous engineering application of technology, some problems have gradually appeared. The most serious is that its special filter material (such as ceramsite) loaded biofilm structure is prone to filter clogging and compaction during long-term operation, which seriously affects biological Filter treatment efficiency. [0003] There are two main reasons: (1) During the operation of the ceramsite biofilter, the ceramsite filter material layer will intercept the suspended soli...
