Abstract

The considerable resources of thermal mineral water of the Paratunskoe Deposit are used in heating systems and balneology. The exhaust water enters a mud-bath water body as feed water. Of interest is the effect of chemical factors of thermal water on the ecological state of the silt sulfide therapeutic mud (peloid). The proportion of thermal water in the feed water of the lake reaches 40%. The effect of thermal water on the peloid structure is simulated by their different concentration used to activate the peloid by liquefaction, heating, mixing, and appropriate oxygen regime (aerobic or anaerobic). The ecological effect of thermal mineral water manifests itself in changes in mud solution chemistry, as well as in the total number of autochthonous microorganisms, and the development of their physiological and geochemical activity. The level of ecological activation is characterized by the number of microorganisms, their physiological activity, physicochemical changes in the mud solution (pH and Eh), as well as the concentration of hydrogen sulfide and ammonia. Small doses are found to have a stimulating effect, while the high proportion of thermal water was found to suppress the geochemical activity of microorganisms. The ecological groups and the lines of physiological activities of microorganisms tolerant to the effect of toxic factors of thermal waters were identified.

矿泉水热毒性因子的理化和微生物基础

摘要

Paratunskoe矿床的相当数量的热矿泉水资源被用于加热系统和皮肤病学。废水作为进水进入泥浴水体。令人感兴趣的是热水的化学因素对淤泥硫化物治疗泥(胶体)的生态状态的影响。湖泊给水中热水的比例达到40%。通过以不同的浓度通过液化,加热,混合和适当的氧气状态(好氧或厌氧)来活化小胶体,可以模拟热水对小胶体结构的影响。热矿泉水的生态效应表现在泥浆化学的变化,土生微生物总数的变化及其生理和地球化学活性的发展上。生态活化水平的特征在于微生物的数量,其生理活性,泥浆溶液中的物理化学变化(pH和Eh)以及硫化氢和氨的浓度。发现小剂量具有刺激作用,而发现高比例的热水可抑制微生物的地球化学活性。确定了耐受热水中毒性因子影响的微生物的生态群和生理活性。同时发现高比例的热水可以抑制微生物的地球化学活性。确定了耐受热水中毒性因子影响的微生物的生态群和生理活性。同时发现高比例的热水可以抑制微生物的地球化学活性。确定了耐受热水中毒性因子影响的微生物的生态群和生理活性。
