Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The invention relates to a tunnel sewage automatic treatment device, which has the following structure: a medicine storage barrel 1 for storing PAC solution 3 is arranged; an input liquid level meter 10 is arranged at a sewage discharge port 12, the input liquid level meter 10 is connected to a liquid level transmitter 5, and the liquid level transmitter 5 is connected to an intelligent light column measuring and controlling instrument 6; the intelligent light column measurement and control instrument 6 is also connected with an adjustable flow pump 8, the inlet end of the adjustable flow pump 8 is connected with a medicine suction pipe 14 arranged in the medicine storage barrel 1, and the outlet end of the adjustable flow pump is connected with a medicine delivery pipe 9 arranged in a sewage discharge port 12; the sewage discharge port 12, the third-stage sedimentation tank 13 and the clear water discharge port 16 are connected in sequence.
Aiming at the liquid level change in the medicine storage barrel 1, when the liquid level rises to the upper limit, the corresponding relay is attracted, the upper limit alarm 18 gives an alarm, and when the liquid level falls to the lower limit, the corresponding relay is attracted, and the lower limit alarm 19 gives an alarm. Aiming at the input type liquid level meter 10 at the sewage discharge port 12, when the liquid level rises to the upper limit, the corresponding relay is closed, the flow-adjustable pump 8 is started, and when the liquid level drops to the lower limit, the corresponding relay is disconnected, and the flow-adjustable pump 8 is stopped.
The adopted medicament is 2.5 percent PAC (polyaluminium chloride medicament), and the medicament is added through a medicament adding hole 4 formed in the upper end surface of the medicament storage barrel 1; the medicine storage barrel 1 is made of HDPE (high density polyethylene). A Canoe-Tong DFD-03-07-M electromagnetic pump can be used as the adjustable flow pump 8 in the present invention. The liquid level changer 5 can adopt YW-136P liquid level changer.
As optimization, an automatic water pump controller 2 is arranged and connected to the intelligent light beam measuring and controlling instrument 6, and the automatic water pump controller 2 is connected to a probe 15 arranged in the medicine storage barrel 1; an upper limit alarm 18 and a lower limit alarm 19 are respectively arranged according to the height of the liquid level in the medicine storage barrel 1.
