It is collected to the total channel of water outlet, is discharged except air-flotation process unit, the pressurization reflux pump of floatation reflux module is taken out from total channel is discharged
Partial reflux water is taken to enter dissolving, while air-compressor set pressurizes into dissolving；
When in sludge reflux operational mode, raw water enters the mixing area of precipitation process unit through raw water water inlet line, mixes
It closes after coagulant and raw water are sufficiently mixed by blender through effluent weir, and enters promotion flocculation zone after adding flocculation aid, mention
Mixed raw water is sent into main tank body by the cylinder for rising blender and its outside, and center driving type sludge condensation mud scraper is to raw water
Carry out compression processing, wherein by mud discharging module precipitation process list is discharged in sludge by the sludge hopper of sludge settling to bottom
Except member, alternatively, sludge to be delivered to the inlet of raw water water inlet line by sludge reflux module, the precipitating water on upper layer is through heavy
Shallow lake outlet pipeline, connected channel flow to the contact zone of air-flotation process unit, the appearance gas and precipitating water of the release release of contact zone
It comes into full contact with, enters Disengagement zone afterwards, the Slag Scraping Device at top scrapes upper layer body refuse to dump tank, the precipitating water after processing of bottom
It is collected to the total channel of water outlet through several collector pipes, is discharged except air-flotation process unit, the pressurization reflux pump of floatation reflux module
Enter dissolving from total channel extraction section recirculation water is discharged, while air-compressor set pressurizes into dissolving.
9. as claimed in claim 8 be separated by solid-liquid separation method for concentration, which is characterized in that further include detection raw water turbidity,
The turbidity of effluent quality at first pipeline；
When raw water turbidity is greater than 100NTU, the separation of solid and liquid enrichment facility is in combined running mode；
When raw water turbidity is between 10NTU ~ 100NTU, the separation of solid and liquid enrichment facility is in sludge reflux operation mould
Formula, when detect the turbidity of the effluent quality at the first pipeline less than 3 NTU or when reaching discharge standard, the separation of solid and liquid
Enrichment facility switches to single precipitation process unit operational mode；
When raw water turbidity is greater than threshold value less than difficult-to-settle particle in 10NTU or raw water and algae accounting, the separation of solid and liquid is dense
Compression apparatus is in single air floatation processing unit operational mode.
