A northern karst spring protection and water quality evolution simulation device and simulation method

Abstract

The invention relates to a northern karst spring protection and water quality evolution simulation device. The northern karst spring protection and water quality evolution simulation device includes a water supply device, a seepage device and a spring water control device; a seepage column is a cylindrical structure which is arranged obliquely and simulates a monoclonal structure; the closed end of the seepage column is provided with a water outlet; the spring water control device is arranged at the water outlet; the seepage column is filled with a Cambrian-Ordovician limestone seepage medium; a plurality of pressure measuring openings and water taking openings are arranged at the side wall of the seepage column; the pressure measuring openings are respectively connected with a pressure measuring tube; the pressure measuring tubes are respectively provided with a valve; the water taking openings are respectively provided with a flow meter and a valve; the water supply device comprises a water bearing layer leakage recharge device and a rain water supply device; the side wall of the upper end of the seepage column is provided with an overflow opening; and the overflow opening is connected with an overflow bottle through a pipeline. With the northern karst spring protection and water quality evolution simulation device of the invention adopted, a northern karst spring water quality evolution process can be simulated, and karst spring water quality evolution laws can be explored, and a scientific basis can be provided for the formulation for spring protection measures.

Description

technical field [0001] The invention relates to a simulation device and a simulation method, in particular to a device and a simulation method for simulating the formation, protection, water quality evolution process of northern karst springs and the impact of human mining on spring water. Background technique [0002] Due to the unique ornamental value of the spring, it has been the object of chanting by literati and poets since ancient times. Today, the spring is still the focus of people's attention. On the one hand, this is because the spring provides an ideal water source for human beings, and on the other hand, because the spring can constitute many ornamental landscapes and tourism resources, such as physical therapy springs, drinking springs, etc. The number of springs in our country is countless, the distribution is very wide, and the types are also very rich. There are both ascending springs and descending springs. There are too many famous springs in various place...

Problems solved by technology

However, due to the massive exploitation of karst water since the 1970s, Baotu Spring stopped flowing for the first time in 1972. The flow time was from March 14, 1999 to September 17, 2001, and the spraying was stopped for 926 days

In order to restore and protect the spring water, the local government has adopted many measures to preserve the spring, such as water conservation and spring diversion, closing water plants, reducing the exploitation of self-provided wells, etc. However, the growth of population and the development of industry and agriculture mean that the amount of groundwater must be It will increase, and the waste of water resources will be caused when the groundwater is blindly reduced for spring protection. Therefore, how to reasonably exploit groundwater under the condition of spring protection is a problem before people.
