Description

A multifunctional mobile water purification device

technical field

The invention relates to a coal mine water treatment technology, in particular to a multifunctional mobile water purification device.

Background technique

my country's mining areas and mining cities are seriously short of water. 71% of the country's 96 key state-owned coal mines are short of water, of which 40% are seriously short of water. Especially in the mining areas in western my country, there is less rainfall and the water supply has been in a state of tension for a long time. Taking Datong City, Shanxi Province as an example, it is located in the Loess Plateau in northern Shanxi, with an average annual rainfall of only 400 mm, an average total water resource of 951 million m ³ , and a per capita occupancy of less than 1/8 of the national average. One of the cities with severe water shortage.

my country is the largest coal producer in the world, and its output is about half of the world's total coal output. Large-scale coal mining has left a large number of gobs, storing considerable water resources. There are many sources of supply water in the goaf, such as groundwater, surface water, rainfall, etc. Some old mining areas with a mining history of half a century or even hundreds of years are dotted with goafs, and the amount of accumulated water is immeasurable.

On the other hand, when mining the side and lower coal seams of the gob, the accumulated water in the gob will become the culprit of the mine water seepage accident. According to statistics, water inrush accidents in my country's coal mine goaf (also known as old empty water) account for 80% of all water damage accidents. Therefore, in order to ensure the safety of coal mines, the goaf water has to be dredged. The coal mines in the Datong mining area of Shanxi Province discharge tens of millions of cubic meters of accumulated water in goafs each year, and Tongxin mine alone drains more than 9 million m ³ from an ancient goaf in the past three years. The discharged mined-out water directly enters the river, which will inevitably increase the pollution load of the superficial environment.

In short, many ecologically fragile mining cities in my country are seriously short of water, and the water supply has been in a state of tension for a long time; The pollution load of the supergene environment. Therefore, the development and utilization of goaf water can not only alleviate the tense situation of urban water supply, but also reduce the threat to coal mine safety production, and at the same time protect and surface ecological environment, which can achieve multiple effects.

To develop and utilize water in coal mine goafs, we must first pay attention to two main issues (taking mining areas in western my country as an example). First, the distribution of goafs is not concentrated. Coal mines and their goafs are very scattered. Even in the same coal mine, it is common for goafs to be separated by several kilometers or even dozens of kilometers. Second, the water quality of goafs varies greatly. Some goafs have small burial depths and are closely connected with the surface environment, receiving rainfall and surface water supplies, and are in an open environment; some goafs with large burial depths mainly receive groundwater. The water quality of the goaf in the open environment is quite different from that in the closed environment for a long time.

The disinfection water storage chamber 22 is provided with three outlet pipelines 14 . Take water as needed.

The working process of this embodiment is as follows:

The accumulated water in the coal mine goaf is collected and pumped into the water inlet pipe 1, passing through the fine filter layer 3 and the packing adsorption box 5 successively. The adsorption box 5 is a detachable module, which can be used to absorb suspended particles in the incoming water and reduce turbidity and chromaticity in the raw water.

One side of the filter adsorption chamber 20 is connected with a circulation pump 5 and a two-way valve 2 , and its pipeline forms a closed circuit with the filter adsorption chamber 20 . When the influent water quality is poor, the double-way valve 2 can be opened to return the filtered and adsorbed water to the water inlet for alternate cycle treatment to reduce the difficulty of subsequent treatment; when the filler adsorption in the filler adsorption box 5 reaches full saturation , the two-way valve 2 can be opened, the water inlet is stopped, all the water outlets are closed, and the bottom-up backwashing process is carried out. The precipitated filtrate is reversely discharged through the water inlet pipe 1, so that the packing can restore the adsorption performance.

During the rapid stirring process of the upper mixer, the flocculant is quickly dispersed by the eddy current excited by the double-layer blades 12, and the residual micro-suspended matter in the incoming water Combined with colloidal impurities to form flocs with good sedimentation performance, under the action of gravity, the thick and firm flocs gradually settle down in the sludge hopper of the flocculation and sedimentation chamber 21 .

The sludge at the bottom of the filtration and adsorption chamber 20 and the flocculation and sedimentation chamber 21 is removed through the sludge discharge system. The sludge discharge system is formed by connecting the sewage pipeline 19 and the mud pump 6. The sludge at the bottom of the treatment chamber is sucked and regularly discharged from the device. , the supernatant after flocculation and precipitation falls into the disinfection storage water through the weir flow method.

In the disinfection water storage chamber 22, the built-in disinfection and sterilization box 13 can regularly inject medicines into the water, inhibit and control the ability of reproduction and breeding of harmful bacteria, and ensure that the water quality of the outlet port meets the corresponding hygienic indicators of different water use fields.

A hose connector 16 is connected to the central part of the bottom of the disinfection water storage chamber 22, and the sampling bottle 17 can collect water samples by opening the manual gate valve 15 on the upper part of the hose to detect multiple water quality indicators.

When the location of water use is inconsistent with the location of water purification (that is, near the water accumulation in the goaf of the coal mine), the device can be transported for long-distance water supply by truck after the water storage is completed; in other cases, the device can be used while storing water to achieve continuous and uninterrupted Operation.
