Vapour layer, is beneficial to dehydration, while add water when impeller works, forms strong current, in time by foreign matter that impurity and proportion are little
Take away, be finally completed cleaning；
（4）Detection case is gushed according to river and adds corresponding treatment agent, stir water and medicament with full-automatic agitating device, fully
It is stand-by after the completion of mixing；
Full-automatic agitating device drives stirring vane to carry out being sufficiently mixed stirring by medicament and water using cycloidal pin as power is driven
Mix；One screw pump is set in addition, i.e., is used for flow-reversing impingement liquid again for drug delivery liquid, make inner bucket water stream that turbulent condition is presented,
Aggravation liquid in bucket blending effect, improves the dissolving diffusion levels of solid chemicals, saves mixing time, accelerates dosing dissolving speed
Rate, reaches rapidly-soluble effect, and mixing time is 15-30min；
（5）With pipeline pump by the feed end of the sludge pumping to dynamic mixer after the screening of mud sand separator, at the same time will stir
The medicament mixed also is pumped to the feed end of dynamic mixer by screw pump, by Online Monitoring Control System detection flows and
Mud and medicament are sufficiently mixed, are flocculated by density, dynamic mixer, are then pumped in mud pit；
During work, the driving motor supplies power in dynamic mixer increases mixability, by arranging stirring in delivery pipe
Blade, enables medicament continuous uniform in blender to contact with mud granule, is effectively increased pharmacy particle to colloidal solid
Build bridge and suction-operated, make mixing and flocculating effect be fully improved；Meanwhile, dynamic mixer can be in restriction conduit length
Equipment in give full play to advantage, mixed flocculation effect is good, shorten flocculation mixing length of tube, accelerate hybrid reaction, improve flocculation
Efficiency；
（6）Opening fluid clutch will pass through with the reacted sludge pumping of medicament into filter press in flocculation tank, start press filtration
Processed, the mud cake after press filtration is sent to spoil disposal area by conveyer；
（7）The sandstone of sand washer cleaning is also deposited in the lump spoil disposal area, and is pulled away with car, meets standard or the transhipment of blended landfill
Market；
The mud sand separator by the use of using the vibrating motor that be installed on screen box at 45 ° with horizontal compass screen surface as vibration source, when two
When platform vibrating motor makees synchronous backward rotation, the exciting force produced by its eccentric block is in swashing parallel to vibrating motor axis direction
Power of shaking is cancelled out each other, and is superimposed as one in the exciting force perpendicular to vibrating motor axis direction and is made a concerted effort and be delivered on whole compass screen surface,
So that the material on compass screen surface on screen cloth to the jumping of discharging opening direction, fallen down by sieve aperture less than the material of sieve aperture
Layer, Jing discharging openings flow out Jing after vertical jump in succession, just can reach and enter mud sand separator described in material Jing due to screening process rationally
Row screening and the purpose being classified；Water content of sandstone≤30% after mud sand separator is processed described in, can directly transport outward；
（8）The water being press-filtered out through filter press is limpid, and tests water quality situation, if reaching two grades of municipal sewage plant with subscript
Criterion is flow back to during river gushes；If not up to standard, it is discharged into again after treatment during river gushes.
Compared with prior art, the invention has the advantages that and beneficial effect：
Present configuration is simple, and a kind of easy to assembly, ingehious design of river and lake silt processing meanss can be to river and lake silt
Processed, realized desilting, removal of impurities, dehydration automation mechanized operation, with environmental protection, economic and efficient advantage.
