Embodiment 1

[0097] Such as figure 2 As shown, in this embodiment, the sludge treatment system includes 8 conditioning tanks, numbered 1# to 8#, and 12 plate and frame machines, and the plate and frame machines are numbered 1# to 12#. 1#~4# conditioning pool and 1#~6# plate and frame machine are the 2nd sludge treatment area in the south area, 5#~8# conditioning pool and 7#~12# plate and frame machine are the 3rd sludge treatment area in the north area.

[0098] Set the southern area as the priority mud feeding area, and determine the status of 1#, 2#, 3#, and 4# conditioning tanks in sequence according to the sludge level in the conditioning tank. If the conditioning tank is in the input state, the corresponding conditioning tank will enter the mud feeding state Queuing sequence, control the mud entering the conditioning tank with the longest time in the mud feeding queuing sequence.

[0099] After all the 4 conditioning pools in the south area have been filled with mud, the north area ...

Abstract

The invention discloses a sludge treatment system and a sludge treatment method, belongs to the technical field of sewage treatment, and solves the problems that in the prior art, an operator needs tomonitor the sludge feeding and discharging processes of a conditioning tank and a plate frame machine in the whole process, and human resources are occupied. The sludge treatment method comprises thefollowing steps: acquiring the liquid level or stirring time parameter of sludge in a regulating tank; determining state information of each regulating tank according to the parameters; determining an identifier of the regulating tank entering the sludge feeding or discharging queuing sequence according to the state information; determining the identifier of the regulating tank with the highest priority in the sludge feeding or discharging queuing sequence; according to the determined identifier of the regulating tank with the highest priority, controlling the corresponding regulating tank tofeed sludge or discharge sludge; determining the identifier of a plate frame machine entering the dehydration queuing sequence; determining the identifier of a plate frame machine with the highest priority in the dehydration queuing sequence; and controlling sludge in the corresponding regulating tank to be pumped into the corresponding plate frame machines for dehydration. The sludge treatment system and method are suitable for treating sludge.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sludge treatment system and a sludge treatment method. Background technique [0002] A large amount of sludge is generated in the process of sewage treatment, which also needs to be treated. During the sludge treatment process, the sludge is first transported from the sludge storage tank in the sewage treatment area to the sludge storage tank in the sludge treatment area through the sludge delivery pump. After a series of pre-dehydration, digestion and other treatments, the sludge is finally transported to the conditioning tank of the plate and frame machine, where the sludge is conditioned, and then pumped to the plate and frame machine for compression and dehydration. After the sludge cake is formed, it can be exported transported to the next step. [0003] In the prior art, there are multiple conditioning pools, which are divided into the south zone and the north ...
