Description

A mine water treatment system

【Technical field】

The utility model relates to a sewage treatment system, in particular to a mine water treatment system, which belongs to the technical field of environmental protection equipment.

【Background technique】

As we all know, in the process of mine mining, a large amount of mine water will inevitably be produced. On the one hand, because the mine water contains a large amount of suspended solids, salt and other substances, and the chroma, turbidity, COD and SS indicators of the mine water are all seriously exceeding the national discharge standards, random discharge will lead to the destruction of the ecological environment; on the other hand, The random discharge of mine water has also caused a waste of water resources. Therefore, it is imperative to treat mine water.

Therefore, in order to solve the above problems, it is indeed necessary to provide an innovative mine water treatment system to overcome the defects in the prior art.

【Content of utility model】

In order to solve the above problems, the purpose of this utility model is to provide a mine water treatment system with simple structure, high treatment efficiency, low cost and the ability to reuse mine water.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a mine water treatment system, which includes an advection tank, a sedimentation tank, an inclined plate water purifier, a clean water tank, a sludge tank, a plate and frame filter press, a dosing tank device and chlorine dioxide generator; wherein, the advection tank, sedimentation tank, inclined plate water purifier and clear water tank are connected in sequence; the advection tank is also connected to the sludge tank; the sedimentation tank and the sludge tank are respectively connected To the plate and frame filter press; the dosing device is connected to the advection tank; the chlorine dioxide generator is connected to the clear water tank.

The mine water treatment system of the utility model is further configured as follows: a flow meter and a turbidity meter are installed on the pipeline between the inclined plate water purifier and the clear water pool.

The mine water treatment system of the utility model is further configured as follows: the plate and frame filter press is connected to the inclined plate water purifier through a return pipe.

Compared with the prior art, the utility model has the following beneficial effects: the mine water treatment system of the utility model has many advantages such as simple structure, high treatment efficiency, low cost, ability to reuse mine water, and saving water resources.

【Description of drawings】

Fig. 1 is a functional block diagram of the mine water treatment system of the present invention.

【detailed description】

Please refer to the accompanying drawing 1 of the description, the utility model is a mine water treatment system, which consists of an advection tank 1, a sedimentation tank 2, an inclined plate water purifier 3, a clean water tank 4, a sludge tank 5, and a plate and frame filter press Machine 6, dosing device 7 and chlorine dioxide generator 8 and other parts.

Wherein, the advection tank 1, the sedimentation tank 2, the inclined plate water purifier 3 and the clear water tank 4 are connected in sequence. The advection tank 1 is also connected to a sludge tank 5 . The advection pool 1 is rectangular, and the mine water flows in from one end of the pool, flows through the pool in the horizontal direction, and flows out from the other end of the pool. At the same time, the sludge in the advection pool 1 is transported to the sludge pool 5, which can remove suspended solids. It can remove about 40%-50% of SS and 20-30% of BOD at the same time, which can reduce the organic load of subsequent structural system units.

The sedimentation tank 2 and the sludge tank 5 are respectively connected to a plate-and-frame filter press 6, and sludge is temporarily stored in the sedimentation tank 2 and the sludge tank 5 .

The inclined plate water purifier 3 has the advantages of high removal efficiency, short residence time, and small floor space. The water treated by the inclined plate water purifier 3 is discharged into the clean water pool 4 for storage.

The plate and frame filter press 6 is connected to the inclined plate water purifier 3 through a return pipe 9, which is used to separate the water in the sludge, and discharge the separated water into the inclined plate water purifier 3 for further purification .

The dosing device 7 is connected to the advection tank 1 . PAC and PAM can be added to the advection cell 1 through the dosing device 7 . Through the hydrolysis process of PAC, accompanied by physical and chemical processes such as coagulation, adsorption and precipitation, it can effectively remove SS, COD, BOD and heavy metal ions such as arsenic and mercury in water. PAM can effectively remove organic matter in water.

The chlorine dioxide generator 8 is connected to the clear water pool 4, which can disinfect and sterilize the water.

Further, a flow meter 10 and a turbidity meter 11 are also installed on the pipeline between the inclined plate water purifier 3 and the clear water tank 4, and the flow meter 10 is used to control the water outlet speed of the inclined plate water purifier 3 to ensure the purification quality ; And judge the quality of purified water quality by turbidimeter 11.

The specific implementation above is only a preferred embodiment of this creation, and is not intended to limit this creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this creation should be included in this creation. within the scope of protection.
