Description
Technical field
Water method is strained for constant water level sequencing batch process system the present invention relates to a kind of.
Background technique
CWSBR (Constant Waterlevel Sequencing Batch Reactors) i.e. constant water level sequencing batch work
Skill is developed on the basis of SBR technique, using permanent water level the method for operation and strain wetting system to SBR technique carry out
Reaction is held with the flexible water sail that can be moved back and forth and is divided into the three parts of variable volume by transformation, and using permanent water-level decanter into
Row strains water.Make the change water level of conventional SBR technique, intermittent water inflow, interval goes out water running and is changed to CWSBR Dan Chiheng water level, continuously into
Water, continuous effluent operation.
One duty cycle of constant water level sequencing batch technique includes the different stage, there is that strain water etc. into water, reaction, precipitating several
A stage, duty cycle process such as Fig. 1.
Collar plate shape open and close type water decanter water-collecting tray is submerged under working water level.When constant water level sequencing batch process system one
Precipitation process proceeds to after a certain period of time in duty cycle, and collar plate shape open and close type water decanter is opened, constant water level sequencing batch technique system
Clear water in system through precipitating along collar plate shape open and close type water decanter circumferential water feed and imports in water outlet standpipe.Reach pre- when straining water
Collar plate shape open and close type water decanter is closed when fixed quantity.Constant water level sequencing batch technique floor map, as shown in Figure 2.
In operation using the municipal sewage plant of constant water level sequencing batch process system, discovery collar plate shape open and close type strains water
Device there are problems that running mud.
Mud problem is run mainly to be caused by following reason:
1, collar plate shape open and close type water decanter mainly catchments disk by lower part and top floating drum forms.Collar plate shape open and close type is strained
The electric operator promotion disk that catchments that is opened by of hydrophone moves down realization, and closing is from the disk that catchments to moving up
It is dynamic closed with top floating drum.Due to disk deformation, fault of electric actuator or a variety of causes such as stroke is not in place of catchmenting, meeting
It causes collar plate shape open and close type water decanter to be not closed completely, part is had in constant water level sequencing batch process system aeration process containing work
Property sludge mixed liquor enter water decanter, during water outlet these activated sludge flow into clear water zone (in operation be referred to as run
Mud) and influence effluent quality.
It 2, can not in monitored picture in actual motion since collar plate shape open and close type water decanter is submerged under working water level
Identify the open and close state of collar plate shape open and close type water decanter.
3, collar plate shape open and close type water decanter structure is more accurate, complicated, higher to maintenance and repair Capability Requirement.
Summary of the invention
The present invention is to cause displacement mass super to solve to there is the phenomenon that running mud using using existing disc water decanter
Target problem.It proposes a kind of constant water level sequencing batch process system and strains water installations.
A kind of constant water level sequencing batch process system of the present invention strains water installations, which includes two shaft stools 1, two
Root catchments transverse tube 2, catch basin 3, electric pushrod actuator 4, four-way pipe 5,6, two transmission shafts 7 of lead screw and the vertical tube 8 that catchments；
Two shaft stools 1 are fixed on the pool wall in pond by fixing piece, and one end of two transmission shafts 7 is separately fixed at
Two are catchmented on transverse tube 2, and the other end of two transmission shafts 7 is connect with two 1 bearings of shaft stool respectively；Two transverse tubes 2 that catchment
One end is connect with two mouths of 5 transverse direction of four-way pipe respectively, and the other end of two transverse tubes 2 that catchment is closed, the upper port of four-way pipe 5
Equipped with blind plate, the upper port airtight connection of the blind plate and four-way pipe 5, the upper end for the vertical tube 8 that catchments and the lower port of four-way pipe 5 connect
It connects；
One end of lead screw 6 is connect with electric pushrod actuator 4, and the other end of lead screw 6 passes through connecting rod and the company of transverse tube 2 that catchments
It connects, inlet is provided on two transverse tubes 2 that catchment, catch basin 3 is arranged on the inlet.
Using it is of the present invention strain water installations when by four-way pipe and catchment vertical tube flanged joint first, will be with catchmenting
The transverse tube open at one end that catchments of slot is slidably inserted into the four-way pipe that catchments, and the transverse tube that will catchment is installed in shaft stool, by one end of lead screw
It is connect with the connecting rod to catchment on transverse tube, the other end of lead screw is connect with Electric Actuator.Lead to when Electric Actuator rotates in the forward direction
Crossing lead screw pushes connecting rod to move downward, and connecting rod drives transverse collector pipe to rotate from the heart, and catch basin is submerged in the water surface and catchments, and collects
Water transverse tube enters the vertical tube that catchments by four-way pipe, and water is strained in realization.When that need to terminate to strain water, Electric Actuator reversely rotates silk at this time
Thick stick pulls connecting rod to move upwards, and connecting rod drives collector pipe to prolong from heart rotation, and catch basin rise leaves the water surface finally perpendicular to the water surface
Water process is strained in end, is effectively avoided and is run mud phenomenon, improves displacement mass.
