Embodiment 1

[0036] In a mine of Pingmei Group in Pingdingshan City, high turbidity mine water treatment process.

[0037] Such as figure 1 As shown, a process for highly efficient deep treatment of mine water using ceramic membranes, the process flow can be found in figure 1 , The raw mine water is first separated and filtered through the primary filter, and the large solids, sawdust, and silk threads larger than 4mm in the mine water are removed, and then the mine water enters the circulating pool (Lipu warehouse), and then enters the ceramic membrane equipment through the pre-membrane preprocessor Ceramic membrane ultrafiltration is performed, and the filtration accuracy of the ceramic membrane tube is 0.04-0.1um. The clean water filtered by ceramic membrane ultrafiltration meets the water quality requirements of the mine's production and domestic water after inspection; the concentrated water enters the circulating pool (Lipu warehouse) through the pipeline for recycling treatment. T...

Embodiment 2

[0039] In a mine of Zhengzhou Coal Group in Xinmi City, Zhengzhou, the general turbidity and low salinity mine water treatment process.

[0040] A high-efficiency and deep-treatment process for mine water using ceramic membranes. For the process flow, see figure 1 , The mine raw water is first separated and filtered through the primary filter. The large solids, wood chips and silk threads larger than 4mm in the mine water are removed, and then the mine water enters the circulating pool, and then enters the ceramic membrane equipment through the pre-membrane preprocessor for ceramic membrane ultrafiltration Filtration, the filtration accuracy of the ceramic membrane tube is 0.04-0.1um. The clear water filtered by ceramic membrane ultrafiltration meets the water quality requirements of the mine's production water and domestic drinking water after inspection; the concentrated water enters the circulating pool through the pipeline for circular treatment. The coal slime precipitat...

Embodiment 3

[0042] In a mine of Pingmei Group in Pingdingshan City, the general turbidity and high hardness mine water treatment process.

[0043] Such as figure 2 As shown in Fig. 1, a high-efficiency deep treatment process for mine water using ceramic membranes. The raw mine water is first separated and filtered through the primary filter. The large solids, wood chips, and silk threads larger than 4mm in the mine water are removed, and then the mine water enters the circulating pool. After the pre-membrane preprocessor enters the ceramic membrane equipment for ceramic membrane ultrafiltration, the filtration accuracy of the ceramic membrane tube is 0.04-0.1um. The clear water filtered by ceramic membrane ultrafiltration meets the water quality requirements of the mine's production and domestic reuse water after inspection; the concentrated water enters the circulating pool through the pipeline for recycling treatment. The coal slime settled in the circulating pool is pumped into the m...

Abstract

The invention provides a process for efficiently and deeply treating mine water by a ceramic membrane, and belongs to the technical field of water treatment. The process comprises the steps that mine water is preliminarily filtered and enters a circulating water pool, then large-particle impurities are removed through membrane pretreatment, and then the mine water is pumped into ceramic membrane ultrafiltration equipment through a water pump to be filtered; clear water obtained after filtering enters a clean water tank to be used as production or domestic drinking water, and concentrated water generated after filtering flows back to the circulating water tank to be mixed with mine water and then is filtered again. The original mine water treatment process is replaced, on-line automatic cleaning of the ceramic membrane deep treatment mine water process is realized, the problems of short equipment operation time, low water production efficiency, high treatment cost and the like can be overcome, and the requirements of continuous development and progress of the industrial technology can be met.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a process for efficiently and deeply treating mine water with a ceramic membrane. Background technique [0002] The lack of drinking water resources is a worldwide problem. For coal mining areas, on the one hand, a large amount of discharge from underground mines causes waste of water resources and environmental pollution. On the other hand, there is a serious crisis in drinking water in mining areas due to water pollution and water shortage. my country's coal mine water treatment technology began in the late 1970s, but most of the sewage treatment work only stays in treatment for discharge, but reuse is the inevitable trend of the development of sewage treatment today. Combining pollution prevention and reuse can not only reduce the pollution of surface water bodies, but also alleviate the contradiction between supply and demand of water sources, killing two birds with o...
