Dynamic quicksand filtering system

Abstract

The invention relates to a dynamic quicksand filtering system which comprises a filtering tank, a water inlet channel, a water outlet channel and filters, wherein the water inlet channel and the water outlet channel are arranged at the front and rear ends of the filtering tank respectively; a water inlet manifold is communicated in the water inlet channel; a water outlet manifold is arranged in the water outlet channel; multiple filters are uniformly distributed and vertically mounted at intervals in the filtering tank; multiple water inlet branch pipes communicated with the water inlet channel in the filtering tank are installed; the water inlet branch pipes are communicated with the water inlet pipe of each filter respectively; and the filters are vertically and fixedly arranged in the filtering tank. In the system, a water outlet channel and a water inlet channel are arranged on the two sides of the filtering tank, multiple quicksand filters are uniformly distributed at intervals in the filtering tank, and large-flow continuous filtration can be realized; the system can be widely applied to the fields of drinking water, industrial water, sewage advanced treatment, reclaimed water reusing and the like, and can replace the traditional high-power back-flushing filtering system; and moreover, the filtered water can reach the national level A and more superior water quality standard, and the system is a novel quicksand filtering system with wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a filter device for sewage treatment, in particular to a dynamic quicksand filter system. Background technique [0002] At present, there are many sewage treatment methods, such as physical filtration, chemical filtration and biological filtration. Physical filtration includes membrane filtration, activated carbon filtration, sedimentation tank filtration, etc. Chemical filtration uses various chemical reagents to flocculate and precipitate sewage. Biological filtration includes Biological strains multiply in the sewage to decompose the sewage, and the above-mentioned various methods can also be combined. [0003] The above three methods are common sewage filtration treatment methods, and all have their own defects: for example, physical filtration must use backflushing to clean the filter medium, chemical filtration makes sewage easy to form secondary pollution, a...
