This paper introduces the test concerning iron removal in the stratum by pumping-recharging circulation after the charging of tap water into a single deep well. While the average iron content in effluent drafted from the well not exceed 0.3mg/L, the withdrawal-recharge ratio may reach 9:1, the dynamic water level in the well is kept stable and operation effect is quite well.

本文介绍了用城市自来水进行回灌的单井抽灌地层除铁试验情况。在井出水平均含铁量不超过0.3mg/L条件下,抽灌比可达9:1,井中动水位稳定,运行效果良好。

Although the underground aquifer has been utilized as a thermal energy storage in winterfilling and summer pumping of deep well for a long period,the theoretical calculating methodfor storage efficiency and temperatures of filling water are still imcomplete.In this paper,asimplified mathematical model is suggested to find the relation between water temperaturesand heat storage efficiency on condition that no loss of cool water exists in the aquifer.First,the fundamental equations of temperature field of aquifer during the process of winter fillingand water temperature variation in summer pumping are derived.In addition,a practicalcalculating method is introduced to solve the problem of temperature distribution in aquiferat the end of three years' winter filling,at the beginning of three years' winter filling andsummer pumping as well as temperatures of pumped water for three years during the periodof summer sumping.From the illustrative example quoted in this paper,its solutions coin-cide basically with the operating data in practice.

深井冬灌夏用,利用地下含水砂层进行蓄热虽已有多年历史,但对其蓄热效率及灌回水温度的理论计算方法尚感不足。本文提出一个较为简化的计算模型,在不考虑地下水流失条件下求解蓄热效率和灌用水温度之间的关系。文中导出冬季灌水过程中地下含水砂层的温度场和夏季抽用水温度变量的基本方程。在此基础上又进一步提出实用计算方法来求解连续三年在冬灌结束、夏用开始时和冬灌开始时地下砂层的温度分布,以及夏用时的抽用水温度。并引倒说明此方法的计算结果基本符合实际运行中测得的数据。

It has been proved that when Fe3O4 magnetic powder and coagulant were put in the raw water to be treated with technique of high gradient magnetic filter, the bacteria in the water might be removed. The removal efficiency of the total amout either of bacteria or of colon bacilli might reach above 99%.However, authors consider that the raw water without being added Fe3O4 magnetic powder and coagulant, the bacteria in the water may also be removed with high gradient magnetic filter. The experiment proves that when...

The removal efficiency of the total amout either of bacteria or of colon bacilli might reach above 99%.However, authors consider that the raw water without being added Fe3O4 magnetic powder and coagulant, the bacteria in the water may also be removed with high gradient magnetic filter. The experiment proves that when the untreated water in Songhua River and deep well water were passed through the high gradient magnetic filter, the bacteria and colon bacilli were also removed. The removal efficiency was above 90%.

用高梯度磁分离技术处理给水,通常在投加Fe3O4铁粉及混凝剂时可以去除水中的细菌。细菌总数和大肠杆菌的去除率均可达到99%.通过试验证明,未经处理的松花江水和深井水直接通过高梯度磁滤器,不投加Fe3O4铁粉和混凝剂,可以去除水中的细菌和大肠杆菌,去除率在90%以上.
