Preface
Water is the source of life and the foundation of urban development. Throughout the ages, whether it is modern society or ancient civilization, human beings are inseparable from the supply and utilization of water resources. In ancient times, due to the limitations of technical conditions, the ancients can be said to have poured out their wisdom in solving the problem of water use, leaving behind many breathtaking construction projects and water conservancy facilities, and these ancient wisdom still play a huge role today.
With the continuous development and progress of society, modern cities are facing increasingly severe water pressure and water supply problems, and some practices and experiences of the ancients in water use can be used for our reference and reference. Therefore, this paper will focus on the water supply system of ancient cities, combined with the water purification and water-saving methods of the ancients, aiming to provide some enlightenment and thinking for the sustainable development of contemporary society through the excavation of ancient wisdom.
1. The water supply system of the ancient capital
The water supply system of the ancient capital city refers to a series of water supply facilities and engineering measures taken by the ancient city to solve the water problem, and its design and construction often require a lot of manpower, material and financial resources, reflecting the importance of the ancients to water resources and the planning of urban development.
# 1. The water supply system of Chang'an City
Chang'an City is the capital of many dynasties in ancient Chinese history, and it is also one of the most far-reaching capitals in ancient China, and its unique geographical environment and climatic conditions have also brought certain difficulties to its water supply.
In ancient times, in order to solve the water problem of Chang'an City, the rulers at that time carried out large-scale water conservancy projects, the most famous is the construction of the Lotus Lake, which has a huge water storage, and around Chang'an City, many artificial canals for water supply were also dug, which introduced the clear river water from the Wei River into the city, providing sufficient water resources for the local residents.
# 2. The water supply system of Luoyang City
In addition to Chang'an City, Luoyang City is also a famous historical and cultural city in ancient China, and the construction of its water supply system also shows the extraordinary wisdom of the ancients in water conservancy engineering.
In the surroundings of Luoyang City, there are dense rivers and water systems, in order to make better use of these natural water resources, the ancients built many water gates and diversion dams in the local area, through precise water conservancy projects, the peripheral river water is introduced into the city, forming an artificial moat and inner city river, these rivers are crisscrossed and crisscrossed, not only to solve the city's water problem, but also to play an important role in flood control and city defense.
2. The water purification methods of the ancients
In addition to building a perfect water supply system, the ancients also attached great importance to the hygiene and health of drinking water in their daily life, so they created many water purification tools and water purification methods to ensure that the water source they drink is clean and hygienic.
# 1. Water bladder filter
Water bladder is a very common filter in ancient times, its principle is very simple, that is, fill the bag with a certain filter medium, such as sand or bamboo charcoal, and then slowly pour water from the mouth of the sac, after the effect of the filter medium, the water in the bag will become clear and transparent, and can be drunk directly.
# 2. Boil water for disinfection
The ancients also attached great importance to the disinfection of drinking water, so in daily life, boiling water disinfection has become an indispensable work, they will take raw water from external water sources, boil and heat, and after the water temperature reaches a certain standard, continue to boil for a period of time, which can effectively kill all kinds of germs and viruses in the water, and ensure the health of drinking water.
# 3. Clean wells regularly
For families with their own wells, the ancients would also regularly clean and maintain the wells to ensure that the surrounding environment of the wells is clean and tidy, and the water quality of the well water is clear, which can effectively avoid the pollution of the well water and also reduce the chance of people getting sick.
3. The water-saving wisdom of the ancients
In ancient times, due to the scarcity of water resources and the backwardness of society, the ancients also had a very deep understanding of water conservation, they not only formed many good habits of water conservation in their daily life, but also promoted the water conservation work of the whole society through legislation and management.
# 1. Water conservation management regulations
For example, in the Ming and Qing dynasties, there were laws and regulations on prohibiting the private digging of deep wells and indiscriminate drainage canals, and the promulgation of these regulations played a very positive role in promoting the protection and rational use of local water resources.
# 2. Collect rainwater
The ancients also attached great importance to the collection and utilization of rainwater resources, they left special rainwater collection devices on the roofs and courtyards of buildings, such as tile ditches and stone buckets, when it rained, rainwater can be effectively collected for life and irrigation, this practice can not only relieve the pressure of rainwater in the city, but also provide people with a certain amount of extraordinary water resources.
epilogue
The ancients said: "The grace of a drop of water should be reciprocated by a spring." "The ancients' emphasis and cherishing on water resources contains awe and gratitude for nature, and their various practices in solving water problems, water purification and water conservation are exactly what we need to learn and learn from.
Nowadays, with global warming and population growth, the problem of water resources has become a major challenge, and in order to fundamentally solve these problems, relying on science and technology and management means alone, it is obviously far from enough, each of us should start from now, cultivate the awareness of water conservation, learn to cherish every drop of water around us, only in this way, can we truly achieve the protection and sustainable use of water resources.
It is hoped that through the introduction and discussion of this article, more people can pay attention to the wisdom of ancient times, and I hope that we can draw strength from the wisdom of the ancients, jointly protect the blue treasures of the earth, and contribute to the construction of a beautiful homeland.
