Abstract
The invention discloses a sewage treatment system, comprising a sewage pool, a water level control device and a water pump, wherein the water level control device comprises a PLC (Programmable Logic Controller), a liquid level sensor and a relay; the liquid level sensor is arranged above the sewage pool and connected with the PLC; the PLC is connected with the motor of the water pump through the relay; and the water inlet pipe of the water pump is connected with the sewage pool. The sewage treatment system is reasonable in structure and capable of automatically controlling the water level of the sewage pool. The flocculating agent employed by the sewage treatment system is capable of effectively depositing harmful substances in wastewater so that the sewage discharged at last is up to the class 1 standard of GB8978-96.
Description
Technical field
The present invention relates to a kind of Sewage treatment systems, is a kind of Sewage treatment systems for pharmaceutical industry specifically.
Background technology
Pharmaceutical industry waste water mainly comprises washing water and the flushing waste water four large classes of production of antibiotics waste water, synthetic drugs factory effluent, Chinese patent medicine factory effluent and all kinds of preparation production processes.The characteristics of its waste water are complicated components, organic content is high, toxicity is large, colourity is dark and saltiness is high, and particularly biochemical is very poor, and intermittently discharged, belongs to unmanageable trade effluent.Along with the development of China's medicine industry, pharmacy waste water becomes one of important source of pollution gradually.
In the Sewage treatment systems that we adopt at present, main still by range estimation to the water level control of sewage lagoon, this just needs the special messenger to process, as long as guarantee that sewage does not overflow just passable, when but the people always has carelessness, in case overflow, can cause serious pollution to environment.
Summary of the invention
The object of the invention is to solve above-mentioned problems of the prior art with not enough, a kind of easy to operate, Sewage treatment systems that level of automation is high is provided.
In order to solve the problems of the technologies described above, the applicant finds that through repetition test for many years the technical solution adopted in the present invention can well reach goal of the invention in all multi-schemes, and the technical scheme that adopts is as follows:
A kind of Sewage treatment systems, comprise sewage lagoon, water-level control apparatus, water pump, described water-level control apparatus comprises PLC controller, liquid level sensor and rly., described liquid level sensor is arranged on the top of sewage lagoon and links to each other with described PLC controller, described PLC controller links to each other with the motor of water pump by rly., and the water inlet pipe of described water pump links to each other with described sewage lagoon.
Described PLC controller is used for the liquid level signal that the receiving liquid level sensor sends, and output starts or stops signal to the rly. open and close.
For the solid substance in the sewage being tackled, improve the work-ing life of water pump, the fence of interception solid substance is installed in described sewage lagoon.
Water outlet at described water pump is connected with flocculation basin, anaerobic pond, Aerobic Pond in turn, and activated charcoal filter is equipped with dosing tank above flocculation basin.
For with the precipitation as much as possible of the objectionable impurities in the sewage, in described dosing tank, flocculation agent is housed, described flocculation agent is that weight ratio is the bodied ferric sulfate of 3:1, the mixture of gac.
Beneficial effect: compared with prior art, advantage of the present invention is: rational in infrastructure, can automatically control the water level of sewage lagoon; Flocculation agent of the present invention is the objectionable impurities in the settled wastewater effectively, thereby so that finally discharged sewage reaches the GB8978-96 primary standard.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Further specify breeding of the present invention and producing method for seed below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of Sewage treatment systems, comprise sewage lagoon 1, water-level control apparatus, water pump 5, described water-level control apparatus comprises PLC controller 3, liquid level sensor 2 and rly. 4, described liquid level sensor 2 is arranged on the top of sewage lagoon 1 and links to each other with described PLC controller 3, described PLC controller 3 links to each other with the motor of water pump 5 by rly. 4, and the water inlet pipe of described water pump 5 links to each other with described sewage lagoon 1.Water outlet at described water pump 5 is connected with flocculation basin 6, anaerobic pond 7, Aerobic Pond 8 in turn, and activated charcoal filter 9 is equipped with dosing tank above flocculation basin 6; Flocculation agent is housed in the dosing tank, and described flocculation agent is that weight ratio is the bodied ferric sulfate of 3:1, the mixture of gac.
Above-mentioned PLC controller 3 is used for the liquid level signal that receiving liquid level sensor 2 sends, and output starts or stops signal to rly. 4 open and close;
Above-mentioned liquid level sensor 2 is for the water level of measuring sewage lagoon 1; Above-mentioned rly. 4 is used for the work of the motor of control water pump 5.
For the solid substance in the sewage being tackled, improve the work-ing life of water pump 5, the fence of interception solid substance is installed in described sewage lagoon 1.
Principle of work of the present invention: the water level that at first detects sewage lagoon 1 by liquid level sensor 2, and water level signal is delivered to PLC controller 3, when water level surpasses the water level alarm value of PLC controller 3 settings, rly. 4 is opened, thereby drive water pump 5 with in the sewage suction flocculation basin 6 that rises above the warning line, add flocculation agent according to the water yield that flows in the flocculation basin 6, every cubic metre of water drops into the 5kg flocculation agent, then the water in the flocculation basin 6 is passed through successively anaerobic pond 7, Aerobic Pond 8, activated charcoal filter 9, final qualified discharge.
Above-mentioned embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
