The adjusting tank is connected with the adjusting tank lifting pump, the adjusting tank lifting pump is connected with the triple box, the triple box is connected with the sedimentation tank, a mud scraper is arranged in the sedimentation tank, the mud scraper is connected with a rotating speed and torque sensor used for measuring the torque of a main shaft of the mud scraper, a sludge discharge port is formed in the middle of the bottom of the sedimentation tank, a sludge hopper is arranged below the sedimentation tank, the sludge hopper is connected with the sludge discharge pump, the sludge discharge pump is connected with the extruding machine, the extruding machine is provided with a sludge cake discharge port and a filtrate discharge port, and the adjusting tank is provided with a filtrate return port; and the rotating speed and torque sensor, the sludge discharge pump and the extruding machine are respectively connected with the main control computer.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a purification treatment system and a purification treatment process for wastewater containing sludge. Background technique [0002] Wastewater sludge purification system is an indispensable pretreatment system in wastewater treatment. Its purpose is to precipitate and remove sediments, suspended solids, and sundries in wastewater. It is generally composed of buffering, dosing, sedimentation, and sewage Sludge conveying, sludge dehydration, filtrate return and other devices. The buffer system is composed of a regulating tank, agitator and a pump, and is used to store wastewater. The purpose is to provide the ability to adjust the water volume during system operation, and to undertake the reprocessing and impact resistance functions when the filtrate is returned. The dosing device consists of a dosing pump, dosing box, agitator, etc. Generally, there are ...

AI Technical Summary

Problems solved by technology

[0003] In terms of the overall operation control mode of the wastewater sludge purification system, the current technology mainly uses dosing equipment to do quantitative dosing, and the sedimentation tank is discharged regularly after sedimentation. According to the situation, the sludge is discharged every 8 hours or after manual detection. The filter press dehydrates the sludge, unloads the sludge manually, and returns the filtrate to the buffer tank for reprocessing. The degree of automation is low, the labor intensity is high, and the plate and frame filter press occupies a large area. There are 2-3 full-time people in the shift to perform operations such as dosing, measuring mud level, unloading mud from plates and frames, etc.
