Description
Technical field
The present invention relates to the test simulation systems technology field of potable water water supply network, particularly a kind of circulation pipe network water quality comprehensive simulation test system with temperature control system.
Background technique
Water supply network is the important component part in the water supply system, and its effect is that the water that meets national Drinking Water water standard after purifying through water factory is delivered to user terminal.Every index of China's most waterworks effluent quality can both reach or be better than national water quality standard for drinking water, but when being delivered to the user by pipe network, often not reaching standard even jeopardize user's body health.Data shows, the water of waterworks is from the user of dispatching from the factory, and water quality presents the trend of obvious reduction, shows that mainly the content in water such as iron, manganese, colourity, turbidity, total number of bacteria increases, even surpassing NBS, this much all finds in the actual motion of water factories at home to some extent.In addition, although the develop rapidly of water technology has fully guaranteed to handle safety, the health of back water quality, but the secondary pollution problem in the pipe network has become influences the principal element that effluent quality can't be up to standard, is water quality research work and water treatment main research work.
Water supply network is just as a sensitivity, dynamic and have a huge reactor of self-characteristic, water is owing to the holdup time in pipeline is long, itself constantly be subjected to polluting once more, complicated physics, chemistry and biology taking place in pipeline changing, cause the decline of sanitary condition in the pipeline.According in " town water supply industry technological progress development plan in 2000 " domestic 34 main cities ductwork water quality data being added up, what surface water water factory output water was basicly stable accounts for 21%, corrosively accounts for 50%, slight fouling accounts for 29%.What underground water water factory output water was basicly stable accounts for 50%, mordantly accounts for 30%, slight corrosively accounts for 20%.To accounting for 36 urban surveys of national total supply 42.44%, the output water average turbidity is 1.3 degree, and pipe network water is increased to 1.6 degree; Colourity is increased to 6.7 degree by 5.2 degree; Iron is increased to 0.11mg/l by 0.09mg/l; Total number of bacteria is increased to 29.2cfu/ml by 6.6cfu/ml.Certain city finds that the thickness of pipe scale in the water pipe reaches 16～20mm, redness of the skin or complexion, fishy smell is arranged, contain 16 kinds of metallic elements, detect 6 kinds of microorganisms such as iron bacteria, dust Xi Shi Escherichia coli and (see Qin Qiuli, Chen Jingyan for details, China's town water supply safe condition is analyzed and the guarantee countermeasure, water conservancy economy, 2001.5).According to city's results of regular determination pipe network roughness coefficient statistics such as Shanghai, Tianjin, find that the pipeline water delivery ability of no anti-corrosion measure has reduced more than 1/3.Pipeline scale, water delivery water quality deterioration, pipeline water delivery ability drop have become the ubiquitous phenomenon of public supply mains.
Expansion and propelling and the progress of society and the raising of living standards of the people fast of town and country one way of supplying water along with China completed region of the city, the resident no longer only has been confined to the guarantee of the pressure and the water yield for the requirement of potable water, but the more concern quality problem, the water stabilization of public supply mains and safety problem are urgent day by day.Drinking water quality is not only up to standard when dispatching from the factory, and need be up to standard at user's water tap place, meets water quality standard for drinking water.And most important in carrying as potable water, also be that the health of the most responsive link-water supply network then is prerequisite and the basis that ensures final leading effluent quality safety.Change of water quality mechanism in the research pipe network proposes and the relevant reply of checking technical measures, is the key point of guaranteeing the inner health of pipe network and ensureing final pipe network tip effluent quality safety.
Carry out above research work, the pipe network experimental study is a basic means, can realize by the research technique of three levels.The most direct is to carry out site test, but exists external condition uncontrollable, is difficult to carry out the problem of quantitative study targetedly, and more crucial is that the test pipe network relates to huge numbers of families, can not add the medicament of test easily; The simplest is to carry out indoor beaker test or build simple local reaction device test, but this class test water sample is few, can not do long-time loop around test, and there is serious test problem of dtmf distortion DTMF in the real working condition ratio with actual pipeline.Therefore both at home and abroad many research institutions all are inclined to and adopt the testing apparatus of circulation pipe network model that true pipe network is carried out high analogue simulation, provide panorama to show and analyze.
In the prior art, circulation pipe network simulation of water quality pilot system both domestic and external all adopts the open cycle mode, promptly is connected with a low level wet pit in the circulating line loop, and current back by the road flow into wet pit, pass through elevator pump then, water is risen in the pipe-line system circulate.This wet pit promptly is that the former water allotment of test pond has scavenging action again concurrently, but the general scale of building up of open cycle pipe network pilot system is less, cyclic design is all very simple, and circulation loop is shorter, can not calculate the circulation pipe network water quality comprehensive simulation test system of high emulation on the essential meaning.Exist mainly in design specifically that flow condition emulation is poor (all to be contacted with the air large size when water sample that at every turn circulates is flowed through wet pit, can influence cycle water; And the Yuan Shui pond participates in the pipe network loop around test, and there is some difference for flow condition and actual pipe network), condition control deficiency (as can't be to full-section pipe-flow pressurized control in the circulation loop, can not water main pipe network that is virtually reality like reality pressure running environment arranged; The test water temperature is subject to the influence of environment temperature in four seasons in the circulation loop, the running temperature that can't temperature control be embedded in underground true water main pipe network), the big a lot of technical problems such as (as chlorine residue decay maximum effect factor of influencing actual pipe network are the pipe network water temperature, can't temperature control as if pilot system then will exist than mistake with actual pipe network operation result) of simulated condition single (as can't realize the simulation that multi-water resources character is switched, double water source mixes all kinds of complex working conditions such as waters supply, external source contaminativity water quality mutation, pipe network secondary chlorination), analog distortion with simulation.

In order to get rid of the bubble in the water in the independent loops pipe network subtense angle circulation loop, the water outlet of described high-order moisturizing exhaust water tank is positioned at the bottom of high-order moisturizing exhaust water tank, promptly be positioned at high-order moisturizing exhaust water tank sidewall or high-order moisturizing exhaust water tank bottom surface near high-order moisturizing exhaust water tank bottom surface, the water intake of described high-order moisturizing exhaust water tank is higher than the water outlet of high-order moisturizing exhaust water tank and is lower than high-order moisturizing exhaust water tank case Senior Two/one position.Like this, the water intake of high-order moisturizing exhaust water tank just is higher than the water outlet of high-order moisturizing exhaust water tank, and the ducted water of independent loops pipe network subtense angle just has certain drop when flowing through, and bubble will rise because density is little like this, easily discharges.
Described loop is being respectively equipped with the 3rd valve and the 4th valve near the water intake of high-order moisturizing exhaust water tank with near the position of the water outlet of high-order moisturizing exhaust water tank; Described loop is connected with the first pipeline branch road with the 5th valve of the branch road parallel connection that is composed in series by the 3rd valve, high-order moisturizing exhaust water tank and the 4th valve; Based on above-mentioned design, the present invention just can realize switching between accurate closed circulation and the closed circulation by the switching between each valve, when closing the 3rd valve and the 4th valve, open the 5th valve, just can realize closed circulation completely, and, the 5th valve is the process modulating valve, can be under the constant situation of main circulating pump frequency, regulate " full-section pipe-flow " pressure in the control closed circulation loop by aperture, can simulate the different hydraulic pressure of the water quality transportation of actual pipe network transportation.
The pipeline that described independent loops pipe network subtense angle is a plurality of and a plurality of independent loops pipe network subtense angles is identical or different; The pipeline of described independent loops pipe network subtense angle is ductile iron pipe, polyethylene pipe (PE pipe), copper pipe or Stainless Steel Tube.The pipeline of independent loops pipe network subtense angle is exactly the carrier that the water in the circulation pipe network flows, it also is transportation environment, because the pipeline of unlike material is to the degree varies sample of the secondary pollution of water, the concrete chemistry that takes place, physics also can be different with biological the variation, therefore, the present invention has chosen ductile iron pipe commonly used in actual pipeline, the PE pipe, copper pipe, Stainless Steel Tubes etc. are as the pipeline of independent loops pipe network subtense angle, to study of the influence of different pipelines to change of water quality in the transportation pipe network, relevant reply technical measures are proposed, and the validity of the relevant reply of checking technical measures.
Water supply subtense angle among the present invention can link to each other with a plurality of independent loops pipe network subtense angles, a plurality of independent loops pipe network subtense angles all can independently be tested, link to each other with four independent loops pipe network subtense angles as a water supply subtense angle, promptly the pipeline of a water supply subtense angle connection independent loops pipe network subtense angle is the independent loops pipe network subtense angle of ductile iron pipe, the pipeline of independent loops pipe network subtense angle is the independent loops pipe network subtense angle of PE pipe, the pipeline of independent loops pipe network subtense angle is that the independent loops pipe network subtense angle of Stainless Steel Tube and the pipeline of independent loops pipe network subtense angle are the independent loops pipe network subtense angle of copper pipe.
In order to monitor the ducted water quality situation of independent loops pipe network subtense angle, the pipeline of independent loops pipe network subtense angle is connected to the water quality monitoring system of the water quality that is used for monitoring circuit water, sampling is used for the water yield of water quality monitoring on the pipeline of independent loops pipe network subtense angle, be considerably less, almost can ignore, generally just can finish moisturizing (under the special test situation by the retaining in the high-order exhaust replenishing water tank of water, moisturizing demand in the pipeline of independent loops pipe network subtense angle surpasses the available maximum rate of water make-up in the high-order exhaust water supply tank, can also pass through water charging system moisturizing in time).Under the bigger situation of moisturizing demand, can pass through water charging system moisturizing in time.Therefore, generally speaking, water sample can directly enter trench through water quality monitoring system.But reduce of the influence of the water yield of collection water sample in order to try one's best to water in the pipeline of independent loops pipe network subtense angle; Described water quality monitoring system can not be made up of by the circulating line branch road water quality monitoring circulating line branch road and water quality monitoring; Described water quality monitoring circulating line branch road comprises conductivity meter, pH instrument and dissolved oxygen testing instrument in parallel, and the two ends of described water quality monitoring circulating line branch road are communicated with the pipeline of independent loops pipe network subtense angle respectively.Because monitored conductivity, water body pH monitoring and dissolved oxygen monitoring do not relate to chemical change, just can monitor, therefore, the water quality of water is basic identical in the water quality of the water sample of above-mentioned process monitoring and the pipeline of independent loops pipe network subtense angle, water sample after the monitoring can be got back in the pipeline of independent loops pipe network subtense angle by the water quality monitoring circulation loop once more, for the foregoing reasons, monitored conductivity, water body pH monitoring and dissolved oxygen monitoring can be adopted real-time monitoring, promptly monitor at any time, can not cause the unstability of the ducted current of monitoring independent loops pipe network subtense angle, wherein, described monitored conductivity, water body pH monitoring and dissolved oxygen monitoring can be adopted commercially available instrument and equipment.
Described water quality monitoring can not comprise residual chlorine detecting instrument, turbidity detector and granule content detector in parallel by the circulating line branch road, described water quality monitoring can not the circulating line branch road an end be communicated with the pipeline of independent loops pipe network subtense angle, the other end inserts trench.Because chlorine residue monitoring, turbidity monitoring and granule content monitoring need to add medicament, changed test water water quality in the circulating line, or diversion come out to detect the back decompression can't get back in the pipeline of independent loops pipe network subtense angle by pressure difference again, therefore, can only enter in the trench, wherein chlorine residue monitoring, turbidity monitoring and granule content monitoring can adopt commercially available instrument to monitor, and in order to reduce the loss of water sample, the intermittently mode of periodic monitor is taked in the test of these three indexs.But the people for open, closing operation, also can open automatically according to initial time, the blanking time set, after reaching stabile test needed time and transmission and showing read signal, close automatically.
