[0028] Specific implementation mode one: combine Figure 1-Figure 8 Describe this embodiment, the biocatalytic electrolysis-anaerobic hydrolysis acidification coupling strengthening refractory wastewater treatment device in this embodiment includes a sewage inlet pipe 1, a sewage outlet pipe 2, a reactor 3, a sewage return pipe 4, and five hydrolytic acidification baffles Plate 5, cathode 9, anode 10 and reference electrode 11, five hydrolytic acidification baffles 5 are evenly and vertically arranged in the reactor 3, and the upper edge of the hydrolytic acidification baffle 5 is lower than the upper edge of the reactor 3 , five hydrolytic acidification baffles 5 divide the inner chamber of the reactor 3 into six compartments from left to right, the first compartment to the fifth compartment are hydrolytic acidification compartments, the sixth compartment is a sedimentation compartment, sewage The water inlet pipe 1 is arranged on the upper part on the left side of the first ...

specific Embodiment approach 2

[0032] Specific implementation mode two: combination Figure 1-Figure 8 Describe this embodiment, the refractory wastewater treatment device of this embodiment also includes deflector 14, and deflector 14 is fixed on the lower end of baffle 13, and forms 135 ° clips between deflector 14 and baffle 13 horn. Such setting facilitates uniform distribution of water and ensures sufficient mixing of sewage and sludge. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0033] Specific implementation mode three: combination Figure 8 To describe this embodiment, the materials of the anode 10 and the cathode 9 in this embodiment are graphite particles. Such setting can effectively reduce the cost. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

[0034] In this embodiment, cheap graphite particles are used as electrode materials, and titanium baskets welded with titanium wires are used as current collectors, and graphite particles are tightly packed into the titanium baskets to form electrodes. Among them, the anode is domesticated and started in the microbial fuel cell, so that the electrode is oriented and stabilized to form a film, and then moved into the anaerobic baffle reaction device. The arrangement of the anode on the top and the cathode on the bottom can not only give full play to the role of the cathode, but also can Prevent toxic pollutants from poisoning and inhibiting the anode.

Abstract

The invention relates to a hard-degradation-wastewater treatment device and particularly relates to a strengthened hard-degradation-wastewater treatment device with biocatalysis electrolysis and anaerobic hydrolysis acidification being coupled. The strengthened hard-degradation-wastewater treatment device solves the problems that a biological conversion rate of the conventional anaerobic hydrolysis acidification system is low, the tolerance of anaerobic hydrolysis acidification microorganisms to pollutant concentration is limited, and organic acid accumulates in the hydrolysis acidification system. According to the invention, five hydrolysis-acidification baffles are uniformly and vertically arranged in a reactor and divide an inner cavity of the reactor into six chambers from left to right, a sewage inlet pipe is arranged at the upper part on the left side of the first chamber, a sewage outlet pipe is arranged in the middle on the right side of the sixth chamber, each upper chamber cover is covered on the upper end of each chamber, anodes and cathodes are arranged in the chambers to be tested from top to bottom, a blow-down pipe is arranged at the bottom of each chamber, a gas collecting pipe is arranged on each upper chamber cover, and each reference electrode is inserted in each reference electrode insert on each chamber to be tested. The strengthened hard-degradation-wastewater treatment device is applicable to treatment of hard-degradation wastewater.

Description

technical field [0001] The invention relates to a refractory wastewater treatment device, in particular to a biocatalytic electrolysis-anaerobic hydrolysis acidification coupling enhanced refractory wastewater treatment device. Background technique [0002] In recent years, with the rapid development of petrochemical, plastic, synthetic fiber, printing and dyeing industries, various waste water containing a large amount of refractory organic pollutants has increased correspondingly, and their entry into water bodies has caused serious pollution to the environment. The treatment of refractory organic industrial wastewater has long been a problem faced by the environmental engineering field. Although the biological treatment process is recognized as an effective technical method for the treatment of organic wastewater, the biological treatment process of high-concentration refractory industrial wastewater faces the challenges of low biological conversion efficiency, lack of ef...
