Background
Sewage is the effluent from life and production that is contaminated to some extent. The water which loses the original use function is called sewage for short. Mainly used in life, the water contains more organic matters and is easy to treat. The sewage inevitably mixes into the silt in the migration, flow and collection processes. If the sand in the sewage is not settled and separated in advance, the operation of subsequent treatment equipment can be influenced. The most important is to abrade the pump, block the pipe network, and interfere or even destroy the biochemical treatment process. The sewage treatment is a process for purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. The grit chamber is indispensable in the sewage treatment process, and the grit chamber is mainly used for removing sand grains with the grain diameter of more than 0.2mm and the density of more than 2.65 t/cubic meter in the sewage so as to protect pipelines, valves and other facilities from abrasion and blockage. The working principle is based on gravity separation, so the water inflow velocity of the grit chamber is controlled, inorganic particles with large specific gravity sink, and organic suspended particles can be taken away along with water flow.
The grit chamber must clear up after using a certain time, otherwise can influence the effect of grit, and the bottom of general advection formula grit chamber all can dispose row's sand pipe and storage sand jar, but in the use, the volume of storing up the sand jar is certain, needs regularly to be changed, and arranges the sand pipe and can arrange away a large amount of water for sewage can not be handled fully, causes the water source extravagant, simultaneously, if arrange sand pipe block, can lead to inorganic granule to pile up, thereby makes sewage treatment not in place.
An effective solution to the problems in the related art has not been proposed yet.
