Embodiment,
It is big that the waste water that waterworks produces in process of production has turbidity, and the feature that solid content is high if this effluent part is directly discharged into river course, not only causes pollution to river course, also increased the weight of the process load of sewage treatment plant.Do not meet the environmental protection concept of energy-saving and emission-reduction.
This example is after treatment as water source, waterworks using this effluent part, is possible not only to solve plant area's sanitary wastewater and processes problem, also solves the hydropenic problem in summer high temperature water source simultaneously.
The feasibility analysis of this example: owing to, in the waste water that the productive life of waterworks produces, the backwashing wastewater in sludge from sedimentation tank water and filter tank accounts for waterworks waste water
70%
Above.Therefore the way solving problem is the problem solving emphatically solid-liquid separation.Water after separation is reflowable to water source, and the solid after separation can be as plant area's afforested areas earth landfill.Centrifuge dehydration, as the dehydration technique of a kind of efficient maturation, has floor space little, the feature that dewatering efficiency is high, and it is feasible for therefore centrifuge dehydration technology is applied to wastewater from water treatment plant processing.Owing to turbidity and the water yield of waste water have the strongest sensitivity for the time, therefore, using cistern storage, after entering centrifuge after dosing pretreatment, solid-liquid separation can realize waste water and process target.

Wastewater treatment process and principle,
Filter fluorescence method, sludge from sedimentation tank water enter spoil disposal pond, concentrated by fluid pressure type mud scraper and collect after preliminary sedimentation, and its supernatant returns rectangular sedimentation tank by immersible pump or entrance Storm Sewer Network enters river course, and bottom muddy water enters concentration basin by undercurrent pump.Concentration basin takes up an area
250m
2
, using gravity concentration, the waste water in concentration basin is after long-time precipitation concentration, and thickened sludge is at the bottom of pond, and its supernatant concentration is up to standard is discharged into Storm Sewer Network by overflow manner.When thickened sludge concentration reaches
20000mg/L
After drained into counterbalance cell.Counterbalance cell takes up an area
70m
2
, its effect is to collect thickened sludge, it is ensured that the continuous operation of dewatering machine.The volume of counterbalance cell determines the impact resistance of sludge dewatering system.Two opposition points of counterbalance cell are mounted with two electronic impellers, and under the effect of electronic impeller, mud can enter mud mouth and prevent local sludgd deposition phenomenon.Muddy water in axial-flow pump extraction counterbalance cell enters three form flocculation stirring ponds, and the equivalently-sized of three lattice is
1.6
×
1.3
×
2.5m
, pass through in the first lattice pond
PAM
Automatic adding device adds flocculant
PAM
, the mixing speed of the first lattice and the second lattice is respectively
120r/min
With
40r/min
, the 3rd lattice are water storage compartments.The muddy water of axial-flow pump extraction stirring pool the 3rd lattice enters centrifugal dehydrator, passes through
PAM
The muddy water of flocculation, improves dewatering further.After the centrifugal dehydrator mechanical dehydration of high speed rotating, the solid content of mud commonly reaches
25%
Above.Every time after centrifugal dehydrator end of run, use plant area's tap water high pressure rinse mode that centrifugal dehydrator is carried out backwash, prevent the clod of internal residual from hardening, thus affect centrifuge dehydration effect next time.The mud of molding falls into conveying worm from the mud mouth of centrifugal dehydrator, through conveying worm, mud is delivered to heap mud canopy, when mud is piled up to a certain extent, then carries out outward transport concentration landfill disposal.
