FIELD: chemistry.
SUBSTANCE: plant for sewage water purification contains vertical cylindrical body of pump station, divided by horizontal sites into three compartments: receiving tank, intermediate technical compartment and upper ground operation compartment, branch pipes for supply and removal of sewage water, systems of inlet and extract ventilation. In pump station receiving tank there is receiving grid, pump or pumps, pump controlling level sensors. In operation compartment of pump station there is control desk, equipped with remote signal consol, and winch for lifting pump and receiving grid with trash. Receiving grid is made in form of net basket with retractable bottom and receiving branch pipe. Branch pipe of sewage water supply additionally contains locking device, device of automatic blocking of branch pipe of sewage water supply in case when net basket is lifted in order to unload retained in it trash, and sensor signalling that net basket is filled with trash.
EFFECT: increasing operational reliability of installation for sewage water purification.
