Description
Technical Field
[0001] The utility model relates to the technical field of mine water treatment devices, in particular to a new type of closed coal mine underground water treatment equipment. Background Art
[0002] Mine water is generally divided into the following types: conventional mine water, high mineralization mine water, acidic mine water and special polluted mine water. High suspended solids and iron-manganese mine water in coal mines belong to mine water with special pollutants. Iron-manganese groundwater is widely distributed in my country. High suspended solids and iron-manganese mine water are also widely distributed. Because underground water contains a large amount of impurities such as stones and coal slag, it is necessary to treat the underground water in advance before using it. Generally, it is filtered. However, when general filtering water treatment equipment is used, after a long period of filtration, its stones and coal slag are easily accumulated on the filter structure, causing the filter structure to be blocked. It needs to be cleaned to avoid affecting subsequent use. In order to protect the safety of the local water environment and ensure the normal production of coal enterprises, the effluent of coal mine water after treatment must stably meet the discharge standards. The existing "regulation + coagulation sedimentation + filtration" process can basically meet the treatment requirements. However, in some special geological conditions or the irregular use of underground reagents, the organic matter content in mine water is significantly increased, and key indicators such as CODCr and ammonia nitrogen are seriously exceeded.
[0003] The high-turbidity mine water treatment device in a coal mine with authorization announcement number CN 216273516 U includes a sedimentation tank, a drainage pump, a flocculant dosing device, a turbidity tester, a flow meter, a liquid level sensor and a PLC controller. The sedimentation tank includes a first sedimentation tank and a second sedimentation tank, which are connected by a connecting pipe. The turbidity tester and the flow meter are arranged on the connecting pipe. The underground main lane drainage ditch is connected to the first sedimentation tank, the inlet of the drainage pump is connected to the second sedimentation tank, and the outlet of the drainage pump is connected to the mine drainage pipe through a one-way valve. A guide plate is also provided on the inner wall of the connecting pipe upstream of the turbidity tester, and the liquid level sensor is arranged in the second sedimentation tank.
[0004] However, the above and other typical existing technologies still have certain problems when used:
[0005] 1. This patent does not design a filtering and cleaning device for sewage purification. During the later cleaning process, dirt accumulates and blocks the filtering device. Long-term filtration will cause the filter plate to be blocked, reducing the filtration efficiency and even causing sewage accumulation and overflow in the filtering device, causing inconvenience to later use and maintenance.
[0006] 2. The equipment is too simple, and it cannot conduct timely detection and feedback on the treated water quality during the sewage treatment process. When the treated water quality does not meet the standards, it cannot conduct subsequent secondary treatment in time, and cannot guarantee the quality of the treated water. Utility Model Content
