Description

Wastewater rainwater recycling system

technical field

The utility model belongs to the technical field of chemical waste water treatment devices, and relates to a waste water rainwater recycling system.

Background technique

Waste liquid will be produced in the process of chemical production. These waste liquids are toxic to a certain extent, so they cannot be discharged out. They must be treated and recycled by professional companies, but direct treatment is very wasteful.

Utility model content

In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a waste water and rainwater recycling system, which can process waste water, and can collect rainwater for reaction, and can also be used as cooling water.

The technical scheme adopted by the utility model to solve the technical problem is: a waste water rainwater recycling system, including an open-air pool body, the pool body is divided into several water areas by several baffle plates, and each baffle plate There is a square notch on the left or right side, and the baffle with the notch on the left and the baffle with the notch on the right are arranged in sequence, and a basket of activated carbon is placed at the notch, and the notch is used for water The water in the upper water area overflows to the next water area for the activated carbon to absorb the chemical substances in the solution. The uppermost water area is connected to the outlet of the lower end of the reactor, and the lowermost water area is connected to the outer layer of the reactor. , used as cooling water, and the lowest level of water area is provided with a pipeline connected with the sedimentation tank.

A water pump is arranged on the above-mentioned pipeline.

A water inlet pipe connected to the inner layer of the reaction kettle extends from the upper end of the sedimentation tank. Due to further separation in the sedimentation tank, the water meets the requirements of the reaction and can be used as reaction water.

A water pump and a water control valve are arranged on the water inlet pipe.

The beneficial effects of the utility model are: after being in contact with activated carbon for many times, the solution flowing out from the reaction kettle gradually reduces the specific gravity of the chemical components, and gradually becomes water that can be reused, and because the pool body is open, Therefore, the treated water will be mixed with rainwater to form cooling water that can be reused. Here, it can enter the outer layer of the reactor and be used as cooling water. At the same time, the cooling water needs to be further separated from impurities, so that it enters the sedimentation tank for further precipitation. , forming the reaction water located at the upper end of the sedimentation tank, which can enter the inner layer of the reaction kettle through the water inlet pipe for reaction use, which greatly reduces the cost of water, improves the utilization rate of water, and effectively utilizes natural resources such as rainwater , has the characteristics of strong practicability, convenient use, energy saving and environmental protection.

Description of drawings

Fig. 1 is the structural representation of the utility model.

In the figure: 1-pool body, 2-water area, 3-gap, 4-activated carbon, 5-sedimentation tank, 6-pipeline, 7-pump, 8-baffle.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1, a waste water rainwater recycling system includes an open-air pool body 1, which is divided into several water areas 2 by several baffles 8, and on the left side of each baffle 8 or The right side is provided with a square gap 3, and the gap 3 is arranged on the left baffle plate 8 and the gap 3 is arranged on the right side baffle plate 8 in sequence, and a basket of activated carbon 4 is placed at the gap 3 position, and the gap 3 is then It is used for the water in the water area 2 to overflow to the next water area 2 for the chemical substances in the activated carbon 4 to absorb the solution. The uppermost water area 2 is connected to the outlet at the lower end of the reactor. 2 is connected with the outer layer of the reaction kettle and used as cooling water, and the lowest level water area 2 is further provided with a pipeline 6 connected with the sedimentation tank 5 .

A water pump 7 is provided on the pipeline 6 .

The upper end of the above-mentioned settling tank 5 stretches into a water inlet pipe connected with the inner layer of the reactor. Due to the further separation in the settling tank 5, the water has met the requirements of the reaction and can be used as reaction water.

A water pump 7 and a water control valve are provided on the water inlet pipe.

After being in contact with activated carbon 4 for many times, the solution flowing out from the reaction kettle gradually reduces the proportion of chemical components, and gradually becomes water that can be reused, and because the pool body 1 is open to the air, the treated water will Mixed with rainwater to form cooling water that can be reused, here it can enter the outer layer of the reactor and be used as cooling water. At the same time, these cooling water need to be further separated from impurities, thus entering the sedimentation tank 5 for further precipitation, forming The reaction water at the upper end of the pool 5 can enter the inner layer of the reaction kettle through the water inlet pipe for the reaction, which greatly reduces the cost of water, improves the utilization rate of water, and effectively utilizes natural resources such as rainwater. Strong, easy to use, energy saving and environmental protection.
