Embodiment
Below in conjunction with specific embodiment, technical scheme of the present invention is elaborated.
In order to thoroughly understand the present invention, by following description, detailed structure is proposed.Obviously, execution of the present invention is not limited to the specific details that those skilled in the art has the knack of.Preferred embodiment of the present invention is described in detail as follows, but except these are described in detail, the present invention can also have other embodiments.
The present invention sets forth in conjunction with certain city's water-supply plant engineering project, the total water supply capacity 250000m of this water-supply plant
3/ d, by the item design of three phases, treatment capacity is respectively 50000m
3/ d (A), 100000m
3/ d (B) and 100000m
3/ d (C), the former water of plant area is supplied by a house steward.The present embodiment main composition part comprises former water water distribution and micro-tensioning system, flocculation basin kinetic parameter on-line monitoring and feedback optimized system, disinfection reactions parameter real time monitoring and feedback optimized system, pump optimization system joined by water supply pump house and pipeline burst is reported to the police and positioning system.
1. former water water distribution and micro-tensioning system
In A, B, C the third stage of the project, B, C two the phase treatment capacity with employing technique identical, treatment effect is good.The A phase, treatment process was unstable, and effluent quality is poor due to long operational time.Therefore, B, C two processing power of phase should be utilized during water distribution as far as possible, reduce the treatment capacity of A phase.
House steward's inflow, with reference to Fig. 2, according to practical operating experiences, is divided into three flow section by concrete decreasing water distribution method.Flow of inlet water Q<7000m3/h is low processing capacity, now three the phase water factory processing power greatly more than needed, effluent quality can be guaranteed completely, needs to prevent the too small generation causing pipeline to draw sky phenomenon of flow of inlet water, therefore needs the minimum treatment capacity 1000m ensureing the A phase
3/ h, residue flow of inlet water can by B, C two the phase divide equally.Work as Q>10000m
3during/h, the process water yield, close to limit treatment capacity, now should play the maximum capacity (2000m of A phase
3/ h) make to exceed maximum throughput simultaneously part by B, C two the phase share.As flow of inlet water 7000m
3/ h<Q<10000m
3/ h, water treatment building is in a higher load range, now to be adjusted in time each phase water distribution quantity by interval censored data evaluation system and optimization contributes to improving effluent water quality on the whole.As shown in Figure 2, first the assignment of distribution ratio of liquid flow presses QA:QB:QC=1.0:2.0:2.0 setting.Run after a period of time, to A, B, C tri-the effluent quality of phase carry out comprehensive evaluation, by water quality by good to the other assignment (ni) of difference be 1,2,3.Therefore, the process water yield of the processing unit that water quality is poor can cut down 1%Q, and the best processing unit of corresponding water quality can increase 1%Q, and the processing unit of the water quality that mediates does not do and changes.For preventing valve from frequently opening and closing, Nodes is controlled do not regulate in ± 2%Q fluctuation range.For ensureing the aperture requirement of valve, minimum for valve aperture is set to 30 °.
2. flocculation basin kinetic parameter on-line monitoring and feedback optimized system
The keying quantity controlling reaction tank tunnel inlets place gate valve by robot control system(RCS) adjusts the GT value of flocculation tank, thus solves traditional flocculation basin and can not people for a change to flocculate the problem of GT value.Feature is also reaction tank GT value to be shown in real time in robot control system(RCS), is associated, is operated GT value scope and corresponding operating mode preferably, can control course of reaction better by GT value with filter tank performance crushing curve and effluent quality.Because design load is generally preferably hybrid reaction condition, it is the basic design principle of this system that the GT value in adjustment reaction tank levels off to design load, as shown in table 1, specifies according to the valve number that flow of inlet water adjusts.
Table 1 pair electric gate valve closes the regulation of quantity
| Flow Q C(m 3/h) | Valve-off quantity | Valve-off is numbered |
| Q C>3990 | 0 | 0 |
| 3990<Q C≤3570 | 2 | 1，8 |
| 3570<Q C≤3150 | 4 | 1，2，7，8 |
| 3150<Q C≤2730 | 6 | 1，2，3，6，7，8 |
| Q C≤2730 | 8 | 1，2，3，4，5，6，7，8 |
Remarks: 1-is even in order to fluid, and gate symmetry is closed.2-gate valve numbering is depending on on-the-spot actual numbering.
In order to prevent the Nodes flow of inlet water gate valve caused that fluctuates from frequently opening and closing problem, the corresponding valve opening and closing problem in node flow place is specified, for example, 3990m
3/ h is the node flow of valve-off number 0 and 2, if do not specify this flow, then flow is at 3989-3991m
3when fluctuating between/h, gate valve closes number frequently in 0 and 2 changes, can easily cause the damage of gate valve.
Node flow is changed into range flow (for example, node flow ± 100m3/h) and can effectively be solved the problem: when flow is 3991m
3/ h, valve closing quantity becomes 2 from 0, if flow rate fluctuation is 3989m
3/ h, valve is failure to actuate, until fluctuations in discharge is 4090m
3/ h, it is 0 that valve can be readjusted as closing number.
