Embodiment
Technical scheme is elaborated with reference to specific embodiment.
In order to thoroughly understand the present invention, detailed structure will be proposed in following description.Obviously, execution of the invention is simultaneously
It is not limited to the specific details that those skilled in the art is familiar with.Presently preferred embodiments of the present invention is described in detail as follows, but
In addition to these detailed descriptions, the present invention can also have other embodiment.
The present invention is illustrated with reference to certain city's water-supply plant engineering project, the total water supply capacity 250000m of the water-supply plant3/ d, by
The item design of three phases, treating capacity are respectively 50000m3/d(A)、100000m3/ d (B) and 100000m3/ d (C), plant area's raw water by
Piece house steward's supply.The present embodiment main composition part includes raw water water distribution and micro-tensioning system, and flocculation basin kinetic parameter is online
Monitoring and feedback optimized system, disinfection reactions parameter real time monitoring and feedback optimized system, water supply pump house with pump optimization system and
Pipeline burst is alarmed and alignment system.
1. raw water water distribution and micro-tensioning system
A, in B, C the third stage of the project, the treating capacity of the phase of B, C two is identical with using technique, high treating effect.The A phases are due to operation
Time is grown, and handling process is unstable, and effluent quality is poor.Therefore, the disposal ability that should be tried one's best during water distribution using the phase of B, C two, subtracts
The treating capacity of few A phases.
Specific decreasing water distribution method reference picture 2, according to practical operating experiences, is divided into three flow sections by house steward's inflow.Water inlet
Flow Q<7000m3/ h is low processing capacity, now three the phase water factory disposal ability it is greatly more than needed, effluent quality is fully able to obtain
Ensure, it is necessary to prevent flow of inlet water is too small from causing pipeline to draw the generation of empty phenomenon, therefore the minimum treating capacity of A phases need to be ensured
1000m3/ h, remaining flow of inlet water can be divided equally by the phase of B, C two.Work as Q>10000m3During/h, processing water close to limit process amount, this
When should play the maximum capacity (2000m of A phases3/ h) while the part more than maximum throughput is shared by the phase of B, C two.Work as water inlet
Flow 7000m3/h<Q<10000m3/ h, water treatment building are in a higher load range, now commented by interval censored data
Valency system, which carries out adjustment and optimization in time to each phase water distribution quantity, to be helped to improve effluent water quality on the whole.As shown in Fig. 2 stream
The assignment of amount distribution ratio presses Q firstA：QB：QC=1.0：2.0：2.0 set.After running a period of time, the water outlet to the phase of A, B, C tri-
Water quality carries out overall merit, by water quality by good to the other assignment (n of differencei) it is 1,2,3.Therefore, water quality poor processing unit
Processing water can cut down 1%Q, and the best processing unit of corresponding water quality can increase 1%Q, and be in the processing list of middle water quality
Member, which is not done, to be changed.To prevent valve from frequently opening and closing, control at node is not adjusted in ± 2%Q fluctuation ranges.To ensure valve
Aperture requirement, valve minimum aperture is set to 30 °.
2. flocculation basin kinetic parameter is monitored on-line and feedback optimized system
The GT values of flocculation tank are adjusted by the keying quantity of gate valve at robot control system(RCS) control reaction tank tunnel inlets,
So as to solve the problems, such as that traditional flocculation basin can not artificially change flocculation GT values.It is further characterized in that reaction tank in robot control system(RCS)
GT value real-time displays, it is associated with filter tank performance crushing curve and effluent quality by GT values, obtain preferably operating GT value models
Enclose with corresponding operating mode, course of reaction can be better controled over.Because design load is generally preferable hybrid reaction condition, adjust
GT values in whole reaction tank level off to design load be the system basic design principle, as shown in table 1, adjusted according to flow of inlet water
Valve number provide.
Table 1 closes the regulation of quantity to electric gate valve
| Flow QC(m3/h) | Close valve quantity | Close valve numbering |
| QC>3990 | 0 | 0 |
| 3990<QC≤3570 | 2 | 1,8 |
| 3570<QC≤3150 | 4 | 1,2,7,8 |
| 3150<QC≤2730 | 6 | 1,2,3,6,7,8 |
| QC≤2730 | 8 | 1,2,3,4,5,6,7,8 |
Remarks：1- is uniform in order to fluid, and gate is symmetrically closed.2- gate valves are numbered depending on live actual number.
In order to prevent that gate valve caused by flow of inlet water fluctuation frequently opens and closes problem at node, to corresponding valve at node flow
Door keying problem provide, for example, 3990m3/ h is the node flow for closing valve number 0 and 2, if not entering to the flow
Professional etiquette is determined, then flow is in 3989-3991m3When being fluctuated between/h, gate valve, which closes number, to easily cause gate valve frequently in 0 and 2 changes
Damage.
Node flow changes into range flow (for example, node flow ± 100m3/ h) can effectively it solve the above problems：
When flow is 3991m3/ h, valve closes quantity and is changed into 2 from 0, if flowed fluctuation is 3989m3/ h, valve are failure to actuate, until flow
Change turns to 4090m3/ h, it is 0 that valve, which can be readjusted to close number,.
Node flow and corresponding range threshold can be adjusted according to water factory's service data, make the operation of reaction tank not
Disconnected optimization.As shown in figure 4, the flow of inlet water Q and water temperature t that pass through online acquisitionw, can be online with reference to corresponding closing gate valve number n
Show the GT values of course of reaction.By accumulating GT- filter tanks crushing and GT- water quality index characteristic curve data, can obtain it is specific enter
Preferably GT values under water, so as to feedback regulation valve number, obtain the flocculation reaction dynamic conditions more optimized.

Specific implementation method is as shown in Figure 7：After valve event, data collecting system starts to gather first group of data, will adopt
Pressure gauge theory show value is calculated with house steward's flow combination history data curve in the reservoir liquid level collected, then will adopt
The pressure data collected compared with theoretical value, if the real-time collection value of three pressure gauges be below theoretical value 20% (preliminary design value,
Can be optimized according to commissioning test situation) below, then send booster alarm and localization of bursted pipe is carried out by suction wave finder.If
Collection value and theoretical value be in normal fluctuation range, then continue gathered data, when gather second pressure data be need to be with
First pressure data is compared, if in normal range (NR) (program preliminary design value is 10% the first normal sample data) interior ripple
It is dynamic, automatic data acquisition scheme is still returned, if exceeding normal fluctuation range, starts collection value with theoretical value alignment programs to sentence
It is disconnected whether booster to occur.If valve acts, data acquisition restarts from after pressure stability.
