The invention relates to the technical field of
precipitation and
sludge dewatering, in particular to a decontamination and
dewatering land-saving integrated treatment method. When
turbidity removal is taken as a treatment target, the
system comprises a pretreatment and biological enhancement
precipitation and
dehydration integrated tank, a filter tank, a
clean water tank, a drainage tank, a concentration tank and a pump room, when pollutants are removed as a treatment target, the device comprises a pretreatment tank, a biological enhancement
precipitation and
dehydration integrated tank, an
ozone contact tank, an
activated carbon adsorption tank, a filter tank, a
clean water tank, a drainage tank, a concentration tank and a pump room, the biological enhancement precipitation and
dehydration integrated
pool comprises a main
pool body, a
sludge backflow dehydration
machine room, a water inlet
pipe and a water outlet
pipe, the water inlet
pipe and the water outlet pipe are matched, the main
pool body comprises a mixing area, a lifting
flocculation area, a transition area, a
sludge-water separation area, a water outlet area, a sludge concentration area and a sludge
storage area, and the main pool body and the sludge
backflow dehydration
machine room are jointly built to achieve precipitation and sludge dehydration functions. According to the invention, processes of efficient precipitation,
sludge dewatering, biological enhancement and land-saving integration can be taken into consideration, so as to realize dual goals of deep purification of
water quality and recycling of resources.
