Abstract

A filtering layer covers outside a water-collecting groove of a sedimentation pool of a water plant. A horizontal or vertical guide rail is arranged along the surface of the filtering layer, and a cleaning pump capable of moving along the guide rail is arranged on the guide rail and is aligned to the filtering layer. The cleaning pump can clean the filter layer row by row and column by column, and allows the filtering apparatus to be used continuously, so that cleaning frequency of a filtering pool is greatly reduced and the cost is greatly decreased.

Description

A kind of filter of water leg

Technical field

The present invention relates to the filter of the water leg, particularly water leg of sedimentation basin in water factory's water purified treatment.

Background technology

The step of water factory's water purified treatment is coagulation (reaction tank), and deposition (sedimentation basin) is filtered (filtering ponds).The water that has added coagulant is delivered to sedimentation basin and is precipitated.Heavier and bigger flocculate is deposited to the bottom of sedimentation basin, and light and less flocculate still floats over the waters on sedimentation basin top.Water leg is a cuboid.One end of water leg is fixed on the pool wall of sedimentation basin, connects filtering ponds through water pipe.Other of water leg are partly flat to crouch on the water surface of sedimentation basin, and this part evenly is provided with a plurality of water inlets, and the drainage of treating that gets into water leg flows into filtering ponds through water pipe.The flow velocity of each water inlet of water leg is about 0.5 meter per second, and purpose is that the flocculate that reduces sedimentation basin flows into water leg.The flow velocity height can increase flocculate and flow into filtering ponds through water leg, and flow velocity is crossed water that low water leg collects very little, influences output.0.5 meter per second is an optimum flow rate, this flow velocity still drives a part of flocculate and flows into filtering ponds through water leg.Flow into the many filtering velocitys that must reduce filtering ponds filter cleaning water of flocculate in filter tank.When filtering velocity drops to the filtering ponds cisco unity malfunction, must the filtering layer of filtering ponds be washed, promptly rinse the flocculate of filtering layer well.During the flushing filtering layer, drain the water of whole filter tank (tens tons to the hundreds of ton), also will use a large amount of clean water upwards to wash filtering layer, rinse well up to filtering layer from the bottom in filter tank.This filter tank can not be used simultaneously, and influence is produced.

Summary of the invention

The objective of the invention is to provide a kind of filter that flocculate flows into water leg that reduces,, reduce cost to reduce the wash number of filtering layer in the filtering ponds significantly.

Water leg outerwrap filtering layer, filtering layer surface arrangement guide rail is equipped with the scavenging pump that moves along guide rail on the guide rail, and scavenging pump should be aimed at filtering layer to mouth.

Effect of the present invention is that the filtering layer of filter can reduce flocculate inflow water leg.Clean the flocculate of filtering layer line by line at the scavenging pump of filtering layer, filter can be used continuously.Only need the flocculate of the following filtering layer of the washing and precipitating pond water surface, clean the clean water of the water of filtering layer with the filtering layer the inside, the water behind the cleaning filtering layer comes the bottom of sedimentation basin, can not cause the waste of water.Reduce in a large number owing to get into the flocculate of filtering ponds through water leg, can reduce the wash number of filtering layer in the filtering ponds significantly, reduce cost.Increase the bore of each water inlet of water leg, make flow velocity, improve the water yield that water leg is collected, promptly improve output greater than former flow velocity 0.5 meter per second.The proportion of filter is slightly less than one, and it is floated on the sedimentation basin, need not support be set in addition and fix, the convenient popularization and use.
