The roles of the natural development and some properties of the soilsin this area are briefly discussed as follows:The soils are saline and calcareous in nature,in which over 70% of thetotal soluble salts are sodium chloride.Slight to moderate alkalinizationmay be developed,while the total soluble salt contents exceed 0.2%;butgenerally,there is no NaCO_3 present.The ground water table in this areais usally high,and the quantity and constituents of the salts in groundwater are directly varied with and influenced by that contained in the abovesoils.The saline and alkali properties of soils in this area are originatedfrom the parent materials,through the action of the sea water when theywere deposited.As soon as the sea water ceased to affect,the soils as wellas the ground water are gradurally desalinized by natural leaching and thisprocess will be strengthened by the biological activities.As the desalinization of the soils is proceeded further,the ratio ofNa~+/Ca~(++)+Mg~(++)in the soil solution decreased and the amount of the exchan-geable Na on the soil colloidal complex is finally lowered.It is evident thatdesalinization also introduces the dealkalinization of the soils in this area;there is no hazard of strong alkalinization of the soils taken place throughleaching.

本文简要地说明了江苏省沿海地区盐渍土壤的自然发生过程及盐渍特性转化的规律,文中主要论点,可初步归纳如下:1、本区域的土壤,发育于盐渍性的冲积母质,土层中富含以氯化钠为主的可溶性盐类,并呈一定的“碱性”。土壤碱性表现在两方面:一方面是土壤胶体表面存在有较多的吸附性钠,另方面表现在本身具有较高的pH 值。2、在自然发生过程中,土壤盐渍性为地质过程遗留的影响;随受自然降水淋盐,河沟排水排盐及生物作用的影响,开始“脱盐、脱碱”和肥力积累过程,发育成为本区内现存的各种不同盐渍程度的土壤。3、随着土壤脱盐作用的进行,土壤盐渍的组成在变化;主要是可溶性盐阴离子中钠离子的含量淋失较速,最后降低了土壤溶液中Na~+/Ca~(++)比率。由于这种盐渍组成的改变,土壤胶体上吸收性Na~+也相应的降低,从而导致土壤的脱碱作用。因此本区土壤的脱盐不致引起土壤碱化。4、在自然发生过程中,本区域盐渍土的脱盐过程,一直是在潜水位较高的情况下进行的。在脱盐过程中,潜水位经常在临界水位以内,为本区自然脱盐过程中,最大特点;潜水动能和土壤的脱盐过程,存在着许多内在的联系。在一定地区内,一定盐渍程度、盐渍特性的土壤,则常有和其相适应的矿化潜水类型。...

本文简要地说明了江苏省沿海地区盐渍土壤的自然发生过程及盐渍特性转化的规律,文中主要论点,可初步归纳如下:1、本区域的土壤,发育于盐渍性的冲积母质,土层中富含以氯化钠为主的可溶性盐类,并呈一定的“碱性”。土壤碱性表现在两方面:一方面是土壤胶体表面存在有较多的吸附性钠,另方面表现在本身具有较高的pH 值。2、在自然发生过程中,土壤盐渍性为地质过程遗留的影响;随受自然降水淋盐,河沟排水排盐及生物作用的影响,开始“脱盐、脱碱”和肥力积累过程,发育成为本区内现存的各种不同盐渍程度的土壤。3、随着土壤脱盐作用的进行,土壤盐渍的组成在变化;主要是可溶性盐阴离子中钠离子的含量淋失较速,最后降低了土壤溶液中Na~+/Ca~(++)比率。由于这种盐渍组成的改变,土壤胶体上吸收性Na~+也相应的降低,从而导致土壤的脱碱作用。因此本区土壤的脱盐不致引起土壤碱化。4、在自然发生过程中,本区域盐渍土的脱盐过程,一直是在潜水位较高的情况下进行的。在脱盐过程中,潜水位经常在临界水位以内,为本区自然脱盐过程中,最大特点;潜水动能和土壤的脱盐过程,存在着许多内在的联系。在一定地区内,一定盐渍程度、盐渍特性的土壤,则常有和其相适应的矿化潜水类型。在自然发生过程中,随土壤的脱盐和盐渍特性的转化,潜水似亦随之发生相应的淡化和化学性质的变化。二者转化趋势,大致相符。彼此间的关系,是互相依存、互相制约的,在不断运动的过程中,似先有土壤的脱盐,而生导向潜水的淡化;但就土壤脱盐的过程言,本身同时又是潜水淡化的结果。5、在土壤脱盐的过程中,土壤盐分的动能比较复杂,一方面是全区土壤不断地脱盐,另方面是在一定的条件下,又可产生局部地区土壤表层的盐渍化。前者为本区盐渍土壤自然发生过程的实质,后者为临时性现象。此种现象,最终亦必随同潜水的转向淡化而逐渐消除。

North-western China, the salt lakes have different water compositions among themselves and different from sea water composition also. 2) Three kinds of processes for extracting magnisium salt from salt lake water are re-commended,(a)the fractional crystallization processes,(b)lime precipitation processes, and (c) ion exchange processes. 3) In practice, the method used to extract magnesium salt from salt lake water varies with the reserve of...

But the ion-exchango processes are preferable, because of simplicity and avability under different circumstances.

1.远古时代西北范围全系大海,陆地出水之后,地面经复杂之变化,遂使盐湖具有差别悬殊之多样性,湖水之成分互不相同,与海水亦有异。 2.自盐湖水提取镁盐之方法,有三类,(1)分级结晶法类,(2)石灰沈降法类,(3)离子交换法类。 3.自盐湖提取镁盐之详细步骤,因湖水含镁量之多少,及盐湖贮量之大小而不同,但以离子交换法为最合用,因其简单便利能适应不同之情况。

On the basis of experimental results, the following three methods are suggested to prevent the settling of larvae and the killing or removing of adults of fouling mussels in pipelines:1.Sand filtration. Before water is pumped into the pipelines, it is made to pass through sand layer 3 cm. or more in thickness and consisting of grains between No. 40 and No. 60 standard sieve in size. It has been proved, that with such thickness and grain size, the sand layer is effective in preventing the entrance of eggs or...

On the basis of experimental results, the following three methods are suggested to prevent the settling of larvae and the killing or removing of adults of fouling mussels in pipelines:1.Sand filtration. Before water is pumped into the pipelines, it is made to pass through sand layer 3 cm. or more in thickness and consisting of grains between No. 40 and No. 60 standard sieve in size. It has been proved, that with such thickness and grain size, the sand layer is effective in preventing the entrance of eggs or larvae of mussels and other fouling organisms 65u or more in size.2.Poisoning with arsenic trioxide. One of the great difficulties of exterminating mussels is that they are able to protect themselves by closing their valves in the presence of poisonous substances, hence greatly prolonging the time needed for chemical treatment. If chemicals can be found which are poisonous to the mussels but to the presence of which they are not very sensitive then the duration of chemical treatment will be greatly shortened. Experiments prove that arsenic trioxide is the desired chemical, concentration of 100-400 p. p. m. being sufficient to kill the mussels in 20 minutes to 2 hours.3.Chlorinated lime treatment. One percent chlorinated lime, containing 38.6% available chlorine, in sea water is found to be able to dissolve the attached byssus threads of the mussels in 10 minutes. By such a treatment, the mussels will be detached from the pipelines and may be easily washed off with water flow.It is suggested that the second and third treatment may be periodically used before the mussels grow to a size that will be detrimental to the plant equipmants.

本文从三方面提供可能应用于解决管道中贻贝堵塞问题的办法: (1)砂滤法:在海水进入水管前用砂将贻贝幼虫滤去,凡颗粒小于40号筛的砂,厚度在3厘米以上,65微米的贻贝卵或幼虫即不能滤过。 (2)用三氧化二砷杀死巳附着的贻贝成体,优点是贻贝不能发觉,施毒时间短而毒效大,用浓度400—100p.p.m.时20分钟至2小时即可杀死。 (3)用漂白粉使贻贝的附着足丝溶解而将其从水管中冲出的办法,含有效氯为38.6%的漂白粉1%溶液在10分钟内即可使足丝溶解,贻贝脱落。
