The establishment of the first filter beds - the albany filters 興建第一座濾水廠
Firstly , study the hydrodynamic properties in the filtering bed ; secondly , analyze the influencing factors by the method of numerical simulation with the above mathematical model 第二,應(yīng)用試驗建立的滲濾取水水文地質(zhì)數(shù)學(xué)模型,對滲濾取水的取水量影響因素進(jìn)行數(shù)值模擬分析。
( 3 ) the blockage of filtering bed and the thickening of the argitan can cause the change of hydrodynamic properties in the filtering bed , which leads to the decrease of water quantity ( 3 )濾床堵塞和泥膜增厚可能產(chǎn)生濾床中水動力特征的改變,會產(chǎn)生非飽和流導(dǎo)致出水量的衰減。
The second construction phase of the kowloon reservoir began in 1922 and involved extending the filter beds , so that they could filter at least 3 , 580 , 000 gallons per day . the expenses for this were $ 366 , 082 九龍水塘的第二期工程于1922年開展,工程項目包括擴(kuò)建濾水池,使每天濾水能力增至358萬加侖食水,擴(kuò)建費(fèi)用為36
The researches indicated : ( 1 ) the seepage flow field of infiltration diversion is characterized by three - dimensional , saturated and steady flow . there is the close hydraulic relationship between the river and the groundwater in the filtering bed , and the groundwater is confined 研究表明: ( 1 )滲濾取水的滲流場具有典型的飽和三維穩(wěn)定流特征;滲濾取水濾床中地下水與河流的水力聯(lián)系比較緊密,濾床中的地下水處于承壓狀態(tài)。
( 4 ) the maximum water quantity becomes greater , the better is the filtering bed permeability , the higher the river hydraulic conductance , the higher the river level , the larger the water - collecting area and the bigger the distance between collecting pipes . the water quantity varies directly with drawdown ( 4 )濾床的滲透性能越好,河床水力傳導(dǎo)系數(shù)越高,河水水位越高,取水面積越大,取水管之間的間距越大,則最大取水量越大;水位降深與取水量成正比關(guān)系。
The characteristic of power quality signal ' s deal by wavelet multi - resolution decomposition and time - domain analysis is studied then brings forward combine the tow methods and uses it to filter bed yawp , decomposition and feature extraction . 8 kinds of power quality are classified and characterization of sag is specially classified 然后研究了小波多分辨率分解和時域分析電能質(zhì)量信號處理的特點,提出了應(yīng)用兩種方法相結(jié)合的方法,對電能質(zhì)量信號進(jìn)行去噪、分解,通過大量的計算機(jī)仿真工作,對擾動信號進(jìn)行了特征提取。
It is shown that the effect of pac removing fluoride is closely related to ph value and the optimum range of ph value is between 6 . 1 ? 7 . 1 . under this condition , further studies are made on the optimum coagulant dosage , mixing time , artificial turbidity , filtration rate and filter bed ' s depth and the optimum range of these parameters have been determined 堿式氯化鋁的除氟能力與原水的ph值有密切的關(guān)系,除氟最佳ph值范圍為6 . 1 ? 7 . 1 。在此條件下,進(jìn)一步對最佳投藥量、混合時間、反應(yīng)時間、人工輔助投加濁度、濾速及濾層厚度進(jìn)行了研究,確定了其最優(yōu)的取值。
