And the preliminary design must plete design instruction booklet one, Sewage treatment plant flow chart, aeration sand collector chart, oxidation ditch chart, two sink pond chart. This Sewage treatment plant project, the overall scale amounts to 5000 tons/ sewage factory39。 The sludge flow is: From two sink the excess sludge which the pond discharges first to enter the concentration basin, carries on the sludge thickening, after then enters the sludge dewatering workshop further dehydrates, transports to trash fills in buries the field. Water leakage execution country sewage synthesis emission standard (GB89781996) two levels of standards.
