A system for the treatment of process water in integrated trench sludge treatment station

Abstract

The invention discloses a treatment system for process water of an integrated dredging sludge treatment station. The treatment system comprises a sloping plate sedimentation basin, a full-automatic filter located over the sloping plate sedimentation basin and a water pump arranged outside the sloping plate sedimentation basin; the water pump is connected with a water pumping pipe, one end of the water pumping pipe is connected with the water pump, and the other end of the water pumping pipe is arranged under the full-automatic filter and over one row of sloping plates in the sloping plate sedimentation basin. Sewage flows down into the sloping plate sedimentation basin after passing through the full-automatic filter, impurities with the density lager than that of water sink to the bottom of the sloping plate sedimentation basin and are located below the sloping plates, and the sloping plates restrict the impurities with the density lager than that of water to float upward, so that water located under the full-automatic filter and over the sloping plates belongs to process water which can be reused after being filtered, and the process water is pumped out of the sloping plate sedimentation basin through the water pump.

Description

Technical field: [0001] The invention relates to the technical field of environmental protection, in particular to a treatment system for process water of a channel sludge integrated treatment station. Background technique: [0002] The process water of the ditch sludge treatment station has certain requirements on water quality, and the general sewage water quality cannot meet the process needs. At present, the process water of the ditch sludge treatment station at home and abroad mainly uses tap water or treated reclaimed water, tap water and reclaimed water It belongs to primary energy, and the cost is relatively high. At the same time, tap water or reclaimed water is used for the process water of the channel sludge treatment station, which also increases the sewage discharge of the entire treatment station. [0003] The utility model with the application number 201520439486.9 discloses a mobile integrated sewage purification equipment, including a coagulant dosing device...

AI Technical Summary

Problems solved by technology

[0004] The technical problem solved by the present invention: multiple inclined plates in the inclined plate settling tank are fixedly arranged, the inclined angle is fixed, and the size of the sewage circulation gap between each adjacent two inclined plates is fixed. However, the impurities contained in various types of sewage The components are different. A certain type of sewage contains more fine sand impurities. For this type of sewage, the sewage flow pass can be narrowed, while another type of sewage may contain more large particles and heavy substances. For this type of sewage, The sewage flow pass can be enlarged; therefore, the above-mentioned inclined plate cannot adjust the size of the sewage flow pass according to different types of sewage, which is not conducive to the improvement of the efficiency of the inclined plate sedimentation tank
