Problems solved by technology

Due to the complex composition and high degree of pollution of sewage from chemical enterprises, it is difficult for general sewage treatment systems to deal with it. Moreover, the existing sewage treatment system has a relatively low degree of automation and a high degree of manual participation, which not only increases labor costs, but also has manual operations. Many uncertain factors may cause human error in weighing. What is more noteworthy is that the use of strong acid and strong alkali is dangerous. If workers do not operate properly, it will cause serious burns and burns.
[0003] In the prior art, the sewage treatment system generally adopts the pp cotton filter membrane filtration system, and a few of the ceramic membranes only use columnar ceramic membranes. These two membrane systems must be added with a pre-filtration system, otherwise it is easy to block the filter membrane, resulting in Great economic loss, and the sewage treatment system of the prior art mostly adopts single-cycle operation, the membrane treatment strength and flexibility are poor, and it cannot meet the national sewage discharge standard

Embodiment 1

[0020] 1. Sewage containing pH=2 and a fluoride ion concentration of 10000 mg / L enters the reaction tank 6 through the sewage pipeline 1, and the detection electrode 29 of the reaction tank transmits the sensing signal to the LED real-time detector 27 and the control cabinet through the signal line 28. Because pH=2, sewage with a fluoride ion concentration of 10,000 mg / L does not meet the discharge standard of pH=6-8, so the control cabinet 28 transmits the operation signal to the lye water pump 3, the flocculant water pump 4, and the second An electric valve 9 and a second electric valve 10 open the lye water pump 3, the lye enters the reaction tank 6 through the pipeline from the lye storage tank 32, neutralizes the pH value of the sewage in the tank, opens the flocculant water pump 4, and the flocculant liquid Enter the reaction tank 6 through the pipeline, and at the same time, the compressed air enters the aeration device inside the reaction tank 6 through the air pipeline...

Embodiment 2

[0025] 1. Sewage containing pH=12 and fluoride ion concentration of 10000 mg / L enters the reaction tank through the sewage pipeline 1, and the detection electrode of the reaction tank transmits the sensing signal to the LED real-time detector and the control cabinet through the signal line. =12, the sewage with a fluoride ion concentration of 10000 mg / L does not meet the discharge standard of pH=6-8, so the control cabinet transmits the operation signal to the acid water pump 5, the flocculant water pump 4, the first electric valve 9 and The second electric valve 10 opens the acid liquid water pump 5, the acid liquid enters the reaction tank through the pipeline from the acid liquid storage tank, neutralizes the pH value of the sewage in the tank, opens the flocculant water pump 4, and the flocculant liquid enters the reaction tank through the pipeline, and at the same time Compressed air enters the aeration device inside the reaction tank through the air pipeline to accelerate...

Embodiment 3

[0030] 1. Sewage containing pH=6 and fluorine ion concentration of 15000 mg / L enters the reaction tank 6 through the sewage pipeline 1, and the detection electrode 29 of the reaction tank transmits the sensing signal to the LED real-time detector 27 and the control cabinet through the signal line 28. Because the sewage with a fluoride ion concentration of 15000 mg / L does not meet the discharge standards, the control cabinet 28 only transmits the operation signal to the flocculant water pump 4, the first electric valve 9 and the second electric valve 10, and turns on the flocculant The water pump 4, the flocculant liquid enters the reaction tank 6 through the pipeline, and the compressed air enters the aeration device inside the reaction tank 6 through the air pipeline to accelerate the reaction; close the second electric valve 10 and open the first electric valve 9, untreated The sewage that meets the standard circulates in the first internal circulation system, which can not o...

Abstract

The invention discloses an automatic monitoring sewage treating system which is high in intelligence degree, strong in sewage treating force, good in flexibility and low in operation cost. The automatic monitoring sewage treating system comprises a pretreatment system and a separation system and is characterized by being further provided with an inner circulation system and a monitoring control system. The separation system comprises a hollow plate type ceramic film. The automatic monitoring sewage treating system has the advantages that a fore-filtration device is omitted due to the fact that the hollow plate type ceramic film is arranged, the hollow plate type ceramic film is designed in an assembly unit mode, only one assembly is replaced when equipment is damaged, the price is low, the overall service life is long, and enterprise expenses are saved; the artificial participation degree is reduced due to the monitoring control system, the labor cost is reduced, and manual errors produced by manual operation are reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical sewage treatment, and more specifically relates to an automatic monitoring sewage treatment system. Background technique [0002] With the continuous acceleration of human activities, the problem of environmental pollution is becoming more and more serious, and the problem of water pollution is becoming more and more serious. Due to the complex composition and high degree of pollution of sewage from chemical enterprises, it is difficult for general sewage treatment systems to deal with it. Moreover, the existing sewage treatment system has a relatively low degree of automation and a high degree of manual participation, which not only increases labor costs, but also has manual operations. Many uncertain factors may cause human error in weighing. What is more noteworthy is that the use of strong acid and strong alkali is dangerous. If workers do not operate properly, it will cause serious burns and...
