Research On Water Supply Methods And Key Technologies Of Canned Self-lifting High-quality Spring Water In Jinan City

The safety and sanitation of drinking water is the most basic issue of people’s livelihood.To ensure the sanitation and safety of daily drinking water for urban and rural residents can better guarantee and effectively maintain the health of consumers and urban and rural residents.With the further improvement of the quality of daily life of Jinan residents and people,the requirements for the quality and safety of drinking water for households have gradually increased.As a world-famous spring city,Jinan has gradually developed into a label of Jinan’s culture and life.Most citizens living in Jinan have a soft spot for spring water and hope that spring water will be used as a source of drinking water.Therefore,it is a very practical project to study the use of high-quality spring water as direct drinking water for residents of Jinan City,so that the people of Jinan can enjoy the welfare of spring water.Based on the groundwater resources of high quality and excellent quantity in Jinan City,the thesis analyzes Jinan Famous Springs,which are composed of Baotu Spring,Bai Spring and Mingshui Springs,The Baotu Spring area covers 122,000 hectares,with an average monthly water resource of 15 million m~3.The total area of Baiquan Spring is 49,600 hectares,and the average monthly water resource is 11.5 million m~3.The area of Mingshuiquan Spring is 35,500 hectares,and the average monthly water resource is 10 million m3.The average monthly underground water resources of the four major spring groups total 36.5 million m3.The average annual water consumption in the five districts of Jinan is 65.854 million m~3,of which the domestic water consumption is 16.4016 million m3,accounting for only 24.9%of the average water consumption,and the real direct drinking water only accounts for 4%of the domestic water consumption.Based on this calculation,the direct drinking water of Jinan residents is 6.56 million m~3.The average monthly water resource of spring water in Jinan is much larger than that of Jinan residents,which can fully meet the direct drinking demand of Jinan residents.The thesis discusses the water supply method of drinking water in Jinan,and focuses on the process of water supply by self-extracting canned high-quality spring water.At present,there are 6 kinds of spring water supply methods in Jinan,including full pipeline centralized water supply,regional decentralized water supply,fixed water supply station water supply,small and medium tank water supply,barrel(bottle)water supply,and canned self-provided water;The thesis introduces the technological process and technological characteristics of these six modes,and analyzes the use scope of the self-extracted high-quality spring water supply method in Jinan City for the residents of the old communities in Jinan City.The whole process of water supply and water intake process,factory water treatment process,vehicle-mounted water tank transportation and modular water supply equipment canned self-lifting high-quality spring water supply.The thesis analyzes the advancement of the water supply process of canned self-extracted high-quality spring water and the safety and reliability of the water supply quality in Jinan from four aspects:water intake,water production,water delivery and water extraction.The principle of selecting the source of high-quality spring canned water from Jinan City was proposed from three aspects of safety,health and palatableness.At the same time,the quality and quantity of raw water from the high-quality spring water from Jinan city were introduced.The main functions and functions of five key technologies such as multi-media filtration,nanofiltration,four-stage microfiltration,ultraviolet disinfection,and ozone disinfection in water treatment and water production engineering are studied.The hygiene guarantee measures,CIP cleaning and disinfection technology and disinfection plan of the four processes of water intake,water production,water delivery and water extraction are proposed.The thesis conducted a market survey of the expected price of spring water from Jinan residents.Through a survey of drinking water methods,drinking water volume,drinking water prices and expected prices of residents in Jinan,According to the analysis data,10.67%of Jinan residents’drinking water is taken from the community water purifier,and this part of the residents are the target customers of self-providing high-quality spring water supply by canning.About 20%of the water used by residents in Jinan is kitchen water,and20%of the water used in kitchens is drinking water;The drinking water price of residents in Jinan is within 0.3 yuan/L as an acceptable price.Through the cost analysis of the water supply method of canned self-lifting high-quality spring water in Jinan City,the cost of canned self-lifting high-quality spring water is calculated to be 183.47 yuan/m~3;Calculated through production cost data,the market price is 281.11 yuan/m~3,which is within the acceptable range of Jinan residents’drinking water prices;According to the actual situation of Jinan City,it is estimated that the economic benefits of Jinan City’s 1,700 old communities will be 34,,407 million yuan after implementation.
