Wastewater recovery and secondary utilization equipment used for chemical plant

Abstract

The invention discloses wastewater recovery and secondary utilization equipment used for a chemical plant. A structure of the wastewater recovery and secondary utilization equipment used for the chemical plant comprises wastewater treatment equipment, handles, a supporting frame, a water discharge pipe, an electric controller and a water inlet pipe, wherein through a sedimentation chamber, first-step precipitation treatment is conducted on chemical wastewater, impurities in the chemical wastewater precipitate, then by means of a stopping screen board and a second filtering screen board, the impurities are isolated and filtered, through a particle collecting turbine, particle treatment is conducted on the wastewater in a filtering chamber, thus a water vapor biofilm obtains full exchange, organic matters in the wastewater are efficiently treated, moreover, by means of a sub-atmospheric pressure aeration mechanism, external oxygen is introduced into the wastewater, moreover, through backwater mechanisms, the wastewater is stirred, contact of organic matters, microorganisms and dissolved oxygen in the filtering chamber is enhanced, the organic matters in the wastewater is subjected tooxygenolysis, treatment of the chemical wastewater is improved, and the structure is low in cost and suitable for use and popularization.

Description

technical field [0001] The invention relates to the field of industrial waste water treatment, in particular to waste water recycling and secondary utilization equipment used in chemical plants. Background technique [0002] Wastewater recycling, also known as wastewater reuse, means that wastewater is reused after treatment. Due to the shortage of water resources, the water that meets the discharge standard needs to be further treated to meet the recycling requirements of industrial water replenishment. In chemical production, chemical reactions will produce a large amount of industrial wastewater every day. These wastewater contains a large amount of Acidic substances and particles, if these waste water are directly discharged into the air, will cause great harm to water resources and the environment, and even bring harm to the survival of nearby residents and organisms. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present inventio...
