Embodiment 1

[0049] see figure 1 , figure 2 , The invention relates to a solidification and drying treatment equipment for sewage sedimentation sludge.

[0050] In the sewage sedimentation sludge solidification drying treatment equipment of the present invention: one side of the sludge still water tank 1 is connected with the first sewage water inlet pipe 2, the bottom of the sludge still water tank 1 is provided with a sludge discharge port 6, and the first sewage water A sewage turbidity sensing device 3 is installed on the water inlet pipe 2; a crushing mechanism 5 is provided at the bottom of the sludge still water tank 1, and a bottom side power device 4 for driving the crushing mechanism 5 is provided on the outside of the sludge still water tank 1; The sewage in the static water tank 1 is divided into a bottom sludge layer 7 and an upper static water layer 8 after sedimentation.

[0051] In the sewage sedimentation sludge solidification and drying treatment equipment of the prese...

Embodiment 2

[0055] A control system for sewage sedimentation sludge solidification and drying treatment equipment, the control system includes a main treatment controller, the specific control content is as follows:

[0056] (1) The sewage turbidity sensing device 3 senses and monitors the turbidity of the sewage injected into the sludge still water tank 1 by the first sewage inlet pipe, and analyzes the mean value of the turbidity during the entire injection process.

[0057] (2) After the first sewage inlet pipe 2 is filled, the ultrasonic sensing mechanism 9 detects the total height of the sewage in the sludge still water tank 1, and determines the sludge settling time according to the average turbidity information and the total height information of the sewage.

[0058] (3) After the sludge sedimentation in the sludge still water tank 1 is completed, the ultrasonic sensor mechanism 9 detects the height position state of the sludge layer 7 in the sludge still water tank 1 and the positi...

Embodiment 3

[0081] In the present invention, during the sewage sedimentation process in the sludge still water tank 1, corresponding sedimentation chemical reagents can be added according to the dirty components of the discharged sewage to assist in the sedimentation, so as to improve the sedimentation effect.

Abstract

The invention discloses sludge solidification and drying treatment equipment for sewage precipitation, and relates to the technical field of sewage treatment. A vertical ultrasonic sensing mechanism is embedded in one side of a sludge still water tank; a bottom side heating mechanism is arranged on the bottom side of the sludge still water tank; a still water treatment tank is arranged on one side of the sludge still water tank; a second still water pipe is arranged between the still water treatment tank and the sludge still water tank; and a centrifugal pump is arranged on the second static water pipe. The third lifting power device is in driving connection with a water suction disc communicated with the second still water pipe; a water inlet signal sensor located above the horizontal water suction pipe is embedded in the annular side of the water suction disc; a low-level turbidity sensor for sensing and monitoring the real-time turbidity of the static water layer is mounted on the bottom side surface of the water absorption disc. On the premise of ensuring the stability of sludge precipitation, clean water absorption is linearly performed on the still water layer, and a large amount of clean water layer water source with relatively low turbidity is discharged to a subsequent still water treatment tank for subsequent treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to solidification and drying treatment equipment for sewage sedimentation sludge. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. [0003] In many sewages, the content of silt and other pollutants is relatively large, and it is necessary to carry out preliminary separation of pollutants, and then carry out subsequent process treatment on the low-turbidity water source after the separation. [0004] When the sewage is initially separated from the filth, if the filter screen is simply used, not only the filtration accuracy is required, but also the clogging phenomenon is very easy to occur during the filtration. This requires the design of a method with a high degree of separation of turbidity and sewage, which is convenient for subsequent lo...
