Abstract

The invention relates to a homogeneous particle filter material reverse granularity rapid filter which is communicated with a to-be-filtered water inlet pipe and a backwashing water inlet pipe, the rapid filter is sequentially provided with a water distribution chamber, a water distribution system, an under layer, a particle filter material layer, a backwashing water trough and a filtered water collection trough from bottom to top, wherein one end of the filtered water collection trough is provided with a clear water channel, the filtered water collection trough is communicated with the clear water channel, a drainage channel is arranged under the clear water channel, the backwashing water trough is communicated with the drainage channel, and the to-be-filtered water inlet pipe and the backwashing water inlet pipe are communicated with the water distribution chamber to ensure that to-be-filtered water enters from the bottom of the filter; and the filtering material layer thickens from top to bottom and has little resistance and more intercepted suspended matters. Compared with the downward flow positive granularity filter on the same scale, the rapid filter has the advantages of being capable of improving water yield by about 40 percent and saving investment by 30-40 percent, correspondingly reducing volume and obtaining remarkable economic benefit.

Description

technical field [0001] The invention relates to water filtration treatment, especially to urban tap water treatment and upgrading of water plant, urban sewage treatment and sewage plant upgrading, industrial water supply treatment, industrial wastewater treatment, advanced treatment of sewage and wastewater, reclaimed water reuse treatment, reclaimed water Treatment, industrial circulating cooling water treatment, swimming pool circulating water treatment, groundwater iron and manganese removal treatment, low temperature and low turbidity water treatment of homogeneous particle filter material reverse particle size fast filter. Background technique [0002] In the modern water purification process, no matter what kind of new purification equipment appears, rapid filtration is still an extremely important and indispensable purification process. Over the past decades, due to the continuous development of filtration technology, various types of fast filters have appeared. Thes...
