Description

Technical Field

[0001] The utility model belongs to the technical field of polyphenylene sulfide wastewater treatment, in particular to a polyphenylene sulfide wastewater treatment device. Background Art

[0002] Polyphenylene sulfide is a new type of high-performance thermoplastic resin, which is widely used as a structural polymer material. It is widely used as a special engineering plastic after filling and modification. At the same time, it can also be made into various functional films, coatings and composite materials. Polyphenylene sulfide synthetic wastewater belongs to high-concentration organic wastewater and is one of the typical representatives of difficult-to-treat industrial wastewater. Polyphenylene sulfide wastewater treatment system is needed for wastewater treatment;

[0003] Traditional methods for treating polyphenylene sulfide wastewater include two-dimensional electrolysis, three-dimensional electrolysis, activated sludge, biological contact oxidation, etc. Among them, the two-dimensional electrolysis and three-dimensional electrolysis methods have different degrees of fouling problems; the activated sludge method has poor operating stability, is prone to sludge expansion and loss, and has unsatisfactory separation effect; the biological contact oxidation process has a high ability to resist shock loads, but the detached biofilm will cause a high concentration of suspended solids in the effluent.

[0004] The utility model with Chinese patent application number CN201520539299.8 discloses a polyphenylene sulfide wastewater treatment device, including a regulating tank, an advanced oxidation decomposition tank, a hydrolysis acidification tank, a sedimentation tank and a clear water tank connected in sequence, an IC reactor is connected between the hydrolysis acidification tank and the sedimentation tank, and an A / O reactor is connected between the sedimentation tank and the IC reactor. The effect of the above scheme is that the regulating tank regulates the water quality and water volume of the wastewater, the advanced oxidation decomposition tank can crack the difficult-to-degrade organic matter, especially the polymers, benzene compounds and other substances, which can play a good cracking role, reduce the impact load of the wastewater, and create a good water inlet environment for subsequent biochemical reactions, the hydrolysis acidification tank acidifies the water pollutants, provides the necessary volatile fatty acids for the IC reaction, and then degrades the high-concentration COD through the IC reactor, and the A / O reactor ensures the effluent water quality through anoxic and aerobic alternating treatment. The polyphenylene sulfide wastewater is treated step by step, and the impact load is reduced step by step, which ensures the stable operation of the system and the excellent effluent water quality;

[0005] Then, combined with the drawings in the specification, it can be seen that the contact between the liquid and the gas in the middle of the oxidation decomposition barrel is only stirred by a simple mixer, and the contact area between the liquid and the gas is small, resulting in part of the ozone being discharged without contacting the liquid, resulting in a waste of the generated ozone, affecting the cracking effect of the organic matter in the waste liquid.
