Evaluation of drinking water quality and actual conflicts of drinking habits
Enterprises, more and more serious water pollution problem, to the suburban environment and the health of the city a tremendous threat to people's lives, but also aggravated the shortage of water resources, to take practical measures to make a prompt decision, all industrial enterprises discharge standards must be , emissions standards can not be firmly closed down industrial enterprises to carry out technological transformation, mine as much as possible in each plant to establish a viable sewage treatment facilities, and to the treated effluent can be recycled, to improve water utilization, to construction of ecological agriculture and green food processing plants as a breakthrough to reduce agricultural pollution. 3.5 Construction of the vegetation, the vegetation is to increase the construction of surface water infiltration, can increase the rainfall infiltration time,[link widoczny dla zalogowanych], but also reduce peak change the runoff process, the surface water into groundwater and create favorable conditions to increase the amount of karst water supply, which Lan village water sources to protect the main objective of measures: (1) implementation of the regional block, is strictly prohibited cattle and sheep to enter, the gradual recovery of vegetation; (2) to further strengthen and improve the survival rate of afforestation, rapid increase in vegetation cover; (3) strengthen the management of vegetation, protection, prevent damage and soil erosion. 3.6 Citation flood recharge, increase water recharge in karst recharge areas in the building cited Hongjia Recharge Project, increasing the recharge. First, fill in the bare limestone area and the edge fault zone together a small valley from the top down the dam, bank control, layers of storing, the storage under the sink and form a complete water recirculation system. Second, the downstream discharge area and discharge area, the construction of the necessary irrigation works cited and cited Hung Hung Recharge Project, storing excess flood season, that is able to irrigate farmland, but also increase the recharge of shallow groundwater, shallow groundwater mitigation Overexploitation,[link widoczny dla zalogowanych], karst groundwater discharge area to reduce soil layer to the downstream flow of pore water excretion more to achieve the purpose of protection of karst groundwater. 3.7 to strengthen scientific research in protected areas, improve the monitoring network, regular analysis of monitoring data, find the cause of abnormal phenomena in a timely manner to determine the processing method, scientific research, to promote scientific management. Water resources research, is the sustainable use of water resources to support sustainable development of urban economy in need of services. (Continued from page 71) water supply source water quality assessment methods and evaluation of the object are mutually contradictory. 4 drinking water and drinking water consumption of 4.1, the difference between cold water line with people's drinking habits, can not meet drinking water standards play untreated surface water disinfection and purification purposes. But to meet drinking water health standards have been cold water, the boil will appear the following situations: a. When the cold water of high salinity in the drinking water limit, on the cold water after boiling, as water evaporation, water in most of the ion content will rise, water salinity of drinking water will exceed the upper limit of Wuzhou Health value, drinking on human health will be adversely affected. b. When the hardness of cold water in the drinking water of the lower limit (ie soft water), the boiling of water softener will make the water Ca,[link widoczny dla zalogowanych], Mg ions and precipitate scale, so that after boiling drinking water hardness is lower than the lower limit value, people who drink this water will would adversely affect health. The body's calcium, magnesium and bone in the majority there, magnesium deficiency can cause cardiomyopathy, focal necrosis of myocardial fibers, and bone damage, long-term magnesium deficiency can produce fragile bones and teeth disorders. Magnesium have a preventive effect on myocardial necrosis, but too much magnesium can cause loss of calcium from the body. Calcium in human blood too low, weak heart, contraction is not 82 entirely, skeletal muscle excitability enhancement caused by the weak twitch disease; the body when too much calcium in the blood, can in systolic cardiac arrest. C. When the cold water in the human body contains a useful gas,[link widoczny dla zalogowanych], cold water boiling on the cold water will be beneficial to the gas evaporation. 4.2 to drink cold water drinking water supply sources to meet current water quality assessment of the way in which China will meet the current drinking water quality standards is beneficial to human health, but do not meet people's living habits. 5 proposals were evaluated 5.1 has been drinking water quality standards in line with the water, drinking water, the water should cultivate the habit of drinking cold water. 5.2 Evaluation is not assessment or proposed drinking water sources should also be evaluated on the contrast of cold water and hot water. 5.3 The proposed assessment is now at the same time cold water drinking water sources and water evaluation of contrast.
