Abstract

The invention discloses an advanced treatment technology for biochemically hardly degradable organic wastewater, and belongs to the field of industrial wastewater treatment. The system is formed by sequentially connecting a water inlet pH regulating system, a precipitative filter, an advanced oxidation reaction tank, a water outlet pump and a water outlet pH regulating system. By the treatment system, the oxidative decomposition advanced treatment of the biochemically hardly degradable organic wastewater such as pharmaceutical wastewater, chemical wastewater, garbage percolate and the like can be realized, and the biochemical degradability of the wastewater is greatly improved; and the system is combined with a biological treatment technology in a subsequent process, is convenient to operate and control, avoids secondary pollution, and has an obvious treatment effect.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to an advanced treatment system and method for organic wastewater that is difficult to biochemically degrade. Background technique [0002] At present, there are not many treatment processes for refractory biodegradable organic wastewater in my country. In addition, there are the following types: [0003] (1) Fenton's reagent method; [0004] (2) Wet catalytic oxidation method; [0005] (3) Electrolytic catalytic oxidation method; [0006] In the above process (1), Fenton's reagent (Fenton Reagent) was discovered by H.J.Fenton in 1894 and applied to the oxidation of malic acid. Its essence is ferrous ion (Fe 2+ ) and H 2 o 2 The chain reaction between catalyzes the formation of HO · , so that malic acid and other organic matter are finally oxidized to CO 2 and H 2 O. In practical engineering applications, the use of Fenton's reagent method to remove organic wa...
