Description

Water distribution system of filter tank

Technical Field

The utility model relates to a filtering pond accessory technical field especially relates to a filtering pond water distribution system.

Background

The filter is used for filtering, and is used for removing suspended matters in water to obtain water with lower turbidity; some are used to remove water from the sludge to obtain sludge with a lower water content. The filter tank has more types and can be divided into a fast filter tank and a slow filter tank according to the size of the filtering speed. In the current practical application, most of the filter tanks are fast filter tanks. The rapid filter has larger treatment capacity and good effluent quality.

The purpose of using the filter in the wastewater treatment is to remove fine suspended substances in the wastewater, in particular to remove some fine suspended particles and colloidal substances which cannot be removed by biochemical treatment and coagulating sedimentation. At present, the filter is widely used as a three-stage treatment means for further treating the effluent of the second-stage treatment; or as the pretreatment of advanced treatment such as activated carbon adsorption, ion exchange, electrodialysis, reverse osmosis, membrane separation and the like.

The filter has a certain removing effect on turbidity, COD, BOD, phosphorus, heavy metals, bacteria, viruses and the like besides the removing effect on suspended substances. In the urban sewage treatment, the filter tank becomes an indispensable treatment unit in a water treatment and reuse system.

The water resistance of the filter layers gradually increases as the filtered suspension accumulates between the filter layers. At the moment, although the water turbidity can not be greatly changed, if backwashing is not carried out in time, the structure of a filter material layer can be changed due to excessive accumulation of sludge; the cross section and the shape of the filter material are changed in the hollow island, and the filter layer is compacted, etc. Meanwhile, due to the increase of water resistance, the filter layer can also be broken, so that filtered water is short-circuited, and the quality of discharged water is poor.

The filter tank has more types and can be divided into a fast filter tank and a slow filter tank according to the size of the filtering speed. In the current practical application, most of the filter tanks are fast filter tanks. The rapid filter has larger treatment capacity and good effluent quality. There are also many types of rapid filters: according to the form of a filter material layer, the filter material can be divided into a single-layer filter material filter pool (comprising a homogeneous filter layer, an actual grading filter layer and an ideal filter layer), a double-layer filter material filter pool and a multi-layer filter material filter pool; according to the inflow mode, the filter can be divided into a gravity type filter and a pressure type filter; according to the control mode, the filter can be divided into a common fast filter, a siphon filter, a movable cover type filter, a valveless filter and the like. The water distribution system is a supporting facility which is too few in the filter tank.

The water distribution system has the function of enabling backwash water to be uniformly distributed on the plane of the whole filtering device, and meanwhile, filtered water can be uniformly collected during filtering. The water distribution uniformity of the water distribution system has great influence on the backwashing effect. Uneven water distribution can cause that a part of filter layers are not fully expanded, the other part of filter layers are excessively expanded, filter materials cannot be washed cleanly in an area with insufficient expansion, sand leakage can be caused in an area with excessive expansion, and when the supporting layer pebbles move, the sand leakage phenomenon is caused. Therefore, when the water distribution system discharges water, the requirement of uniform flow velocity of water at each position is higher when water is uniformly distributed, and the requirement is difficult to be met when common water pipes are used for water distribution.
