Kev Piav Qhia Luv:

Peb lub tshuab lim sludge siv yog lub tshuab sib xyaw ua ke rau kev ua kom sludge tuab thiab tshem dej. Nws siv lub tshuab ua kom sludge tuab tshiab, yog li muaj peev xwm ua tau zoo thiab cov qauv me me. Tom qab ntawd, tus nqi ntawm cov haujlwm tsim kho vaj tse tuaj yeem txo qis. Ntxiv mus, cov khoom siv lim dej tuaj yeem hloov kho rau ntau qhov sib txawv ntawm sludge. Nws tuaj yeem ua tiav qhov kev kho mob zoo tagnrho, txawm tias qhov sib txawv ntawm sludge tsuas yog 0.4%.

Tom qab lub sijhawm flocculation thiab compression, cov slurry raug xa mus rau ib txoj siv porous rau thickening thiab gravity dewatering. Ib qho dej dawb ntau heev raug sib cais los ntawm lub ntiajteb txawj nqus, thiab tom qab ntawd cov slurry solids raug tsim. Tom qab ntawd, cov slurry raug sandwiched ntawm ob lub tensioned belts kom dhau los ntawm wedge-puab pre-compression zone, low pressure zone, thiab high pressure zone. Nws yog extruded kauj ruam los ntawm kauj ruam, kom ua kom qhov siab tshaj plaws ntawm sludge thiab dej sib cais. Thaum kawg, lub lim ncuav mog qab zib raug tsim thiab tso tawm.
