【摘要】：肥城市作為泰安市重要的工業(yè)區(qū),近年來(lái)工農(nóng)業(yè)用水總量不斷增加,存在地下水過(guò)量開(kāi)采、水環(huán)境惡化等環(huán)境水文地質(zhì)問(wèn)題。本文在系統(tǒng)分析地下水長(zhǎng)期實(shí)測(cè)數(shù)據(jù)基礎(chǔ)上,以肥城市地下水水化學(xué)成分為研究對(duì)象,結(jié)合研究區(qū)水文地質(zhì)條件及地下水歷史資料,運(yùn)用地下水質(zhì)量評(píng)價(jià)、水文地質(zhì)學(xué)及水文地球化學(xué)等方法,對(duì)研究區(qū)水化學(xué)特征及其時(shí)空分布規(guī)律、水化學(xué)特征形成機(jī)制及水文地球化學(xué)過(guò)程,進(jìn)行了研究,形成了階段性成果,得出以下結(jié)論:(1)基于Hydro GeoAnalyst建立了肥城市地下水管理信息系統(tǒng),將搜集到的近30年來(lái)的大量數(shù)據(jù)輸入系統(tǒng)中,實(shí)現(xiàn)了地下水?dāng)?shù)據(jù)的存儲(chǔ)、管理、維護(hù)、查詢、分析以及可視化等功能。(2)選取pH、Cl~-、SO_4~(2-)、TDS、總硬度、NO_3~-、高錳酸鹽指數(shù)和F-等8項(xiàng)指標(biāo),采用F值評(píng)分法進(jìn)行對(duì)地下水質(zhì)量評(píng)價(jià)。地下水水質(zhì)較差區(qū)水主要分布在研究區(qū)內(nèi)西北部石橫鎮(zhèn)以及徑流排泄區(qū)王莊鎮(zhèn),在南部的汶陽(yáng)平原水質(zhì)較為良好。(3)研究區(qū)內(nèi)地下水化學(xué)類型以HCO_3~-Ca型水和HCO_3~-Ca·Mg型水為主,水化學(xué)成分不斷發(fā)生改變,地下水中SO_4~(2-)以及Cl~-占比不斷上升,主要水化學(xué)類型已轉(zhuǎn)變成為HCO3·SO4-Ca·Mg型水為主,占比64.29%,其中還含有HCO3·SO4·Cl~-Ca·Mg型水以及HCO3·Cl~-Ca·Mg型水,主要陰離子由HCO_3~-向SO_4~(2-)和Cl~-離子偏移,TDS及總硬度呈明顯增大趨勢(shì)。(4)研究區(qū)內(nèi)地下水水化學(xué)主要成分在空間分布及變化規(guī)律符合傳統(tǒng)意義上的地下水中離子含量從補(bǔ)給區(qū)經(jīng)徑流區(qū)到排泄區(qū)越來(lái)越高的分布特征,TDS大致由研究區(qū)東北部向研究區(qū)西南部及地下水徑流排泄區(qū)出口逐漸增高。但值得注意的是肥城市北部實(shí)則是地下水補(bǔ)給區(qū),但也發(fā)生了多項(xiàng)離子濃度過(guò)高的情況,該區(qū)域主要是肥城的工業(yè)區(qū)以及煤礦開(kāi)采區(qū),說(shuō)明人類活動(dòng)強(qiáng)度對(duì)地下水水化學(xué)成分的影響在逐漸增加。(5)通過(guò)水文地質(zhì)學(xué)、水文地球化學(xué)及數(shù)理統(tǒng)計(jì)方法,利用Gibbs圖和離子比例系數(shù)等方法作圖分析形成肥城市地下水水化學(xué)特征的主要水文地球化學(xué)過(guò)程,顯示方解石、白云石以及石膏的溶濾作用是引起研究區(qū)內(nèi)地下水水化學(xué)成分變化的主要作用,同時(shí)存在有少部分的鹽巖溶解及陽(yáng)離子交替吸附溶濾作用,使得地下水中Na+、K+離子減少,Ca2+、Mg2+增加。人類活動(dòng)造成含水層結(jié)構(gòu)的變化和工農(nóng)業(yè)生產(chǎn)廢水以及城市生活污水也是地下水成分變化的重要因素。
[Abstract]:Feicheng City is an important industrial area in Taian City. In recent years, the total amount of water used in industry and agriculture has been increasing, and there are some environmental hydrogeological problems such as over-exploitation of groundwater and deterioration of water environment. On the basis of systematic analysis of long-term measured groundwater data, this paper takes the chemical composition of groundwater in Feicheng City as the research object, combines the hydrogeological conditions and historical data of groundwater in the study area, and applies the evaluation of groundwater quality. Hydrogeology, hydrogeochemistry and other methods are used to study the hydrochemistry characteristics and their spatiotemporal distribution, hydrochemical characteristics formation mechanism and hydrogeochemical process in the study area. The main conclusions are as follows: (1) based on Hydro GeoAnalyst, the groundwater management information system of Feicheng City is established, and a large number of data collected in the past 30 years are input into the system to realize the storage, management, maintenance and query of groundwater data. (2) pH,Cl~-,SO_4~ (2-) TDs, total hardness, permanganate index and F- were selected to evaluate groundwater quality. The groundwater in the poor groundwater area is mainly distributed in Shiheng Town in the northwest of the study area and Wangzhuang Town in the runoff discharge area, and the water quality is relatively good in the southern Wenyang Plain. (3) the chemical types of groundwater in the study area are mainly HCO_3~-Ca type water and HCO_3~-Ca Mg type water. The chemical composition of water changed continuously, and the proportion of SO_4~ (2-) and Cl~- in groundwater increased continuously. The main types of hydrochemistry had been changed to HCO3 SO4-Ca Mg type water, accounting for 64.29%, which also contained HCO3 SO4 Cl~-Ca Mg type water and HCO3 Cl~-Ca Mg type water. The shift of the main anions from HCO_3~- to SO_4~ (2-) and Cl~- ions, TDs and total hardness showed an obvious increasing trend. (4) the spatial distribution and variation of the main chemical components of groundwater in the study area were in accordance with the traditional groundwater ion content compensation. The distribution of TDs is increasing from the northeast of the study area to the southwest of the study area and the outlet of the groundwater runoff discharge area. However, it is worth noting that the northern part of Feicheng City is actually a groundwater recharge area, but there have also been many cases of excessive ion concentration. This area is mainly an industrial area in Feicheng City and a coal mining area. It shows that the influence of human activity intensity on the chemical composition of groundwater is increasing gradually. (5) through hydrogeological, hydrogeochemical and mathematical statistical methods, The main hydrogeochemical processes forming the hydrochemical characteristics of groundwater in Feicheng City were analyzed by using Gibbs diagram and ion ratio coefficient, which showed calcite. The dissolution and filtration of dolomite and gypsum are the main factors that cause the change of the chemical composition of groundwater in the study area. At the same time, there are a few salt rock dissolving and cation alternate adsorption leaching. The increase of Ca 2 + mg 2 in groundwater can be reduced by Na K ion. The changes of aquifer structure caused by human activities, industrial and agricultural wastewater and municipal sewage are also important factors for the change of groundwater composition.
