WCX Series Sewage Treatment Plant

WCX series sewage treatment plant with the physicalchemical method processes the sewage from ships. All the structure and performance of this device can meet the requirements of GB1083389 Marine sewage treatment system technical conditions with the features of small size, light weight, compact structure and etc., treated waste water is in line with national regulations of discharge standards, but also to meet international emission standards. This device is running for the automatic control and set up cabinet with alarm systems to display loading conditions of the sewage in them. This device is applicable to sea water and fresh water rinse. Main technical parameters: The quality standards of treated water: Biological oxygen demand / 5 days (BOD5): ≤50mg/l suspended solids (SS): ≤50mg/l MPN: ≤250/100ml PH: 6-9 The number of users: Type Standard volume of flushing water (19 liters/per) Low volume of flushing water (9.5 liters/per) Weight(Kg) WCX-24 24 person 48 person 460 WCX-36 36 person 72 person 580 Maximum equipped with power: 3Kw Smashing pump: 1.5Kw Flow pump: 0.37Kw Sludge return pump to send: 0.37Kw Discharge pump: 0.37Kw Principle: Sewage from the bathroom access first to the device counters, the plant begins to process the work when the waste water in cabinet reaches median. Of its work time is about 18 min and controlled by time relay preferentially. Sewage containing solid residues shattered at a cycle of several times by the crushing pump in counters until the solid residue small enough to be able to get through the filter (stranded/reduction) net. At the same time there is rinse water wash the filter constantly to prevent the accumulation of solid residues from blocking the filter. In the grinding process, adding a certain amount of sodium hypochlorite for disinfection, the addition of disinfectant controlled by the doser automatically. The sewage after crush, filtration and disinfection is pumped into a series of setting tank tandem by process pumps. The velocity in setting tank will slow down and the suspended solids of it sink. The settled sludge will be pumped back by sludge foldback pump to counter carrying through recycled crush. The treated water will be getting clear gradually in series of setting tank. When the clear water in the cabinet reaches the median, discharge pump will work to emission it out of ships side because of the touch of sensor, when it reaches low, the discharge pump stop working automatically.
