In the chemical industry, tetrahydrophthalic anhydride is one of the basic chemical materials. In the production process will produce waste liquid, if the direct discharge will affect the environment, then how to deal with it.

Four hydrogen of benzene anhydride liquid waste processing, there are four hydrogen of benzene anhydride equipment, processing equipment, its structure including filtering tank, described to the left side of the filtering tank is equipped with liquid into the tube, filtering tank with internal baffle, described above mentioned filtering tank is equipped with additives, described the right side of the filtering tank is equipped with liquid pipe, referred to the interior of the filtering tank is equipped with a PH adjustment room, The PH regulation chamber is provided with hydrolytic acidification chamber on the right side of the hydrolytic acidification chamber is provided with a peculiar smell removal chamber, the peculiar smell removal chamber is provided with a standing room on the right side of the PH regulation chamber, hydrolytic acidification chamber and peculiar smell removal chamber are respectively provided with a stirrer, the stirrer is arranged above the stirring motor.

The equipment can effectively purify the waste liquid, reduce the pollution of the environment when the waste liquid is discharged, reduce the pollution of the waste liquid to water resources, improve the protection of water resources, through the design of the deconfilation pipe, can effectively facilitate the removal of sediment in the filter tank, improve the convenience of cleaning the filter tank. When treating tetrahydrophthalic anhydride waste liquid, it needs to be applied to special equipment so that it can be better treated.
