Abstract
The utility model relates to an on-demand chlorine adding control system, which belongs to the field of water treatment. The utility model has the technical scheme that the starting end of a contact chamber is provided with a chlorine adding point and a contact chamber water inlet; a flowmeter is arranged at the position of a bottom contact chamber water outlet; one end of a chlorine adding pipeline is connected with the chlorine adding point; and the other end of the chlorine adding pipeline is connected with a chlorine adding machine controlled by a central control module. The on-demand chlorine adding control system also comprises an ammonia nitrogen online monitor and a residual chlorine online monitor, wherein the ammonia nitrogen online monitor is arranged at the position of the contact chamber water inlet, the residual chlorine online monitor is arranged at the position of the HRT4-6 minute of the contact chamber, and the ammonia nitrogen online monitor and the residual chlorine online monitor are respectively connected with the central control module. The on-demand chlorine adding control system has the beneficial effects that the chlorine demand reaching a certain residual chlorine value is determined according to an ammonia nitrogen value in water and the amount of a reducing substance, and chlorine is added according to the chlorine demand according to needs. The waste caused by the reason that the chlorine is excessively added and the secondary pollution caused by the reason that trichloramine is generated are avoided; the undesirable sterilizing effect and unqualified indexes like fecal coliform and the like which are caused by the reason that the chlorine are insufficiently added are avoided; and the hysteresis quality of adjusting the chlorine dosage according to the tail end residual chlorine value is avoided simultaneously by on-demand chlorine adding.
Description
Technical field
The utility model belongs to water treatment field, relates in particular to the water plant automatic control field.
Background technology
At present sewage work, middle water factory, the waterworks method of adjusting chlorine dosage automatically mainly contains according to the water yield and changes the method for adjusting chlorine dosage and the method for adjusting chlorine dosage according to the terminal chlorine content of contact tank.
Adjust chlorine dosage according to the variation of the water yield, the initial stage is enabled the definite cumbersome of time unit's chlorine dosage, and can occur when water quality changes the time and the chlorination deficiency, the time and the excessive phenomenon of chlorination.Chlorination is excessive to cause waste, also can generate three chloramines and cause secondary pollution; The chlorination deficiency then causes sterilization effect undesirable, and indexs such as excrement large intestine are defective.
Adjust chlorine dosage according to terminal chlorine content, because contact tank needs about 2 hours the residence time, the chlorine content of current measurement is the embodiment of chlorination effect before in 2 hours, adjust chlorine dosage according to this chlorine content, when changing, water quality has certain hysteresis quality, in the time of can occurring equally and the chlorination deficiency, the time and the excessive phenomenon of chlorination.
Summary of the invention
The purpose of this utility model provides a kind of Controlling System of chlorination as required, when sewage work, middle water factory, waterworks effluent adopting chlorination, adjusts chlorine dosage, chlorination as required in real time according to the variation of the water quality and the water yield.
The technical solution of the utility model is:
Chlorination Controlling System as required, initiating terminal at contact tank has chlorination point and contact tank water-in, there is under meter at contact tank water outlet place, bottom, one end of chlorination pipeline connects the chlorination point, the other end connects the chlorinating machine by Central Control Module control, also comprises: ammonia nitrogen on-line monitoring instrument is arranged, on 4-6 minute position of the HRT of contact tank in the contact tank water inlet, chlorine residue on-line monitoring instrument is arranged, all be connected with Central Control Module.
Beneficial effect:
Determine to reach the chlorine demand of certain chlorine content according to the amount of ammonia nitrogen value in the water and reducing substances, according to chlorine demand chlorination as required.Avoided superchlorination to cause waste, and generated three chloramines and cause secondary pollution; Avoided the chlorination deficiency to cause sterilization effect undesirable, indexs such as excrement large intestine are defective; Chlorination has avoided adjusting by terminal chlorine content the hysteresis quality of chlorine dosage simultaneously as required.

Embodiment
Chlorination Controlling System as required, chlorination point and contact tank water-in are arranged at the top of contact tank, there is under meter at contact tank water outlet place, bottom, one end of chlorination pipeline connects the chlorination point, the other end connects the chlorinating machine by Central Control Module control, also comprise: ammonia nitrogen on-line monitoring instrument is arranged in the contact tank water inlet, chlorine residue on-line monitoring instrument is arranged at the middle part of contact tank, all be connected with Central Control Module.
As Fig. 3, Fig. 4, the online data of under meter, ammonia nitrogen on-line monitoring instrument, chlorine residue on-line monitoring instrument input Central Control Module.Under meter is used for measuring the instantaneous delivery of contact tank, ammonia nitrogen on-line monitoring instrument is measured the ammonia nitrogen value that contact tank is intake before being installed in chlorination point, chlorine residue on-line monitoring instrument is installed on HRT 4-6 minute the position of contact tank, this position just in time is that (chlorination does not comprise ammonia nitrogen before the break for hypochlorous acid and reducing substances, chlorination comprises ammonia nitrogen behind the break) the basic complete reaction position of finishing, measure this chlorine content and chlorine dosage and compare the chlorine consumption that can obtain reducing substances in the water into.Central Control Module utilizes the chlorine consumption of ammonia nitrogen value, reducing substances, the instantaneous water yield to converse the chlorine demand of this moment, and then controls chlorinating machine by performer and adjust chlorine dosage in real time, reaches the purpose of chlorination as required.
