The embodiment is as follows:
as shown in figure 1, the utility model provides a wastewater treatment system for titanium dioxide production, which comprises a filtering device 2 and a wastewater treatment system 1. One end of the filtering device 2 is connected with the waste water pipe, and the other end is connected with the waste water treatment system 1. The waste water pipe is a waste water outlet pipe of the titanium dioxide production equipment 7.
The filter device 2 is a filter press. The filter press comprises a feed pump 21. The feed pump 21 is used for pumping the wastewater generated in the production of titanium dioxide to a filter press. The wastewater treatment system 1 is used for treating acidic wastewater filtered by the filter press.
When the wastewater treatment system for titanium dioxide production is used, wastewater generated in the titanium dioxide production process is filtered by the filtering device 2, and titanium dioxide particles mixed with the wastewater are filtered out. Finally, the wastewater treatment system 1 treats the filtered acidic wastewater.
The wastewater treatment system for titanium dioxide production can filter out titanium dioxide particles in wastewater so as to recycle and reduce waste. Meanwhile, after the titanium dioxide particles are filtered out, the treatment of the acidic wastewater is simpler, and the efficiency is improved.
In this embodiment, the inlet of the feed pump 21 is connected to a feed pipe 22 and a water inlet pipe 23. The feeding pipe 22 is connected with a waste water pipe and is used for conveying waste water generated in the production of titanium dioxide to a filter press. The water inlet pipe 23 is used for introducing clean water into the filter press. The water inlet pipe 23 is connected with the clean water tank 6. The outlet of the feed pump 21 is connected to a filter press. Both the feed pipe 22 and the feed pipe 23 are provided with a control valve 3. When the device is used, the control valve 3 of the feeding pipe 22 is opened, the control valve 3 of the water inlet pipe 23 is closed, and wastewater generated in titanium dioxide production is pumped into the filter press through the feeding pump 21. After the pumping is completed, the control valve 3 of the feeding pipe 22 is closed and the control valve 3 of the water inlet pipe 23 is opened, so that clean water is pumped into the filter press. And (3) introducing clean water into the filter press to clean the filtered titanium dioxide particles in the filter press, and further cleaning away the substances such as acid and the like. So that the filtered titanium dioxide particles are purer.
In addition, during the process of pumping wastewater by the feed pump 21, impurities such as titanium dioxide particles in the wastewater can be deposited in the pipeline and the interior of the feed pump 21. In the process that the feeding pump 21 pumps clean water, the clean water washes away impurities such as titanium dioxide particles deposited in the pipeline and the feeding pump 21, and titanium dioxide particle blockage caused by shutdown of the feeding pump 21 is avoided.
In this embodiment, the filter press is provided in plural. Several filter presses are connected to a feed pump 21. The filter press requires a certain amount of time for filtration. And a plurality of filter presses are arranged to ensure uninterrupted filtration. Simultaneously, a plurality of filter presses can also improve efficiency.
In this embodiment, the waste acid treatment device further comprises a concentrated waste acid pool 4 and a clear waste acid pool 5. The water outlet end of the filter press is communicated with a concentrated waste acid pool 4 and a clear waste acid pool 5. And control valves 3 are arranged on connecting pipes between the concentrated waste acid pool 4 and the clear waste acid pool 5 and the filter press. The water filtered by the filter press can be controlled to flow to a concentrated waste acid pool 4 or a waste acid cleaning pool 5 by controlling the two control valves 3. When the feed pump 21 pumps wastewater into the filter press, the water flowing out of the water outlet end of the filter press is concentrated acid. This water is discharged into the concentrated spent acid pond 4. When the feed pump 21 pumps clean water into the filter press, the water flowing out of the water outlet end of the filter press is clean waste acid. This water is discharged into the spent cleaning acid basin 5. This allows the waste water of different concentrations to be stored separately.
In this embodiment, the water inlet pipe 23 is connected to the acid cleaning and waste pool 5 and the clean water pool 6. Control valves 3 are arranged between the waste acid cleaning pool 5 and the clean water pool 6 and between the feeding pumps 21. The water level clear water or the low-concentration acidic wastewater pumped into the filter press can be controlled by controlling the two control devices. After the titanium dioxide in the filter press is cleaned by clean water, the acid concentration of the effluent water is still lower. It can be cleaned again. This reduces the amount of fresh water used and reduces emissions.
In this embodiment, the control valves 3 are all solenoid valves. The opening and closing of the control device is controlled by the controllers such as the PLC and the like conveniently, the automatic control is facilitated, and the labor intensity is reduced.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
