SYSTEM FOR DISCHARGING WASTEWATER SUBJECTED TO SAMPLING ANALYSIS OF BALLAST WATER TREATMENT SYSTEM AND SHIP

摘要

A system for discharging wastewater subjected to sampling analysis of a ballast water treatment system, and a ship. The wastewater discharge system comprises: a collecting cabinet (1) located under a sampling analysis unit and used for collecting wastewater subjected to sampling analysis; a ballast pump (2), an inlet pipe (21) of the ballast pump (2) being selectively communicated with a wastewater discharge pipeline (11) of the collecting cabinet (1), and an outlet pipe (22) of the ballast pump (2) being communicated with a ballast main pipe and being used for discharging the wastewater in the collecting cabinet (1) into the ballast main pipe; a pneumatic diaphragm pump (3) provided on the wastewater discharge pipeline (11); and a touch assembly connected with the pneumatic diaphragm pump (3) and associated with the liquid level in the collecting cabinet (1). When the liquid level in the collecting cabinet (1) reaches the set value, the touch assembly drives the pneumatic diaphragm pump (3) to automatically open. According to the wastewater discharge system, the wastewater subjected to sampling analysis can be automatically collected and discharged individually, and the arrangement of the pipelines of the whole wastewater discharge system is very simple.
