Abstract

The invention discloses a bioreactor for treating high-salt organic wastewater based on a composite salt-tolerant bacterial strain. The bioreactor comprises a plurality of anaerobic reactors and aerobic sewage treatment devices which are sequentially communicated in series through communicating pipes, a supporting pore plate is fixedly arranged at the lower end in each anaerobic reactor, a fillerparticle bed layer is laid on each supporting pore plate, salt-tolerant anaerobic bacteria are added into each anaerobic reactor, and a first water distribution pipe is laid at the bottom in each anaerobic reactor; when every two adjacent anaerobic reactors are communicated in series through a communicating pipe fitting, a water filter screen is arranged at an inlet in the front end of the communicating pipe fitting and horizontally extends into the upper end of a previous anaerobic reactor, and an outlet in the rear end of the communicating pipe fitting is communicated with the first water distribution pipe laid at the bottom of the interior of a next anaerobic reactor; after anaerobic treatment, the wastewater flows into an aerobic sewage treatment device for aerobic treatment. The bioreactor disclosed by the invention is relatively high in high-salt organic wastewater treatment efficiency and low in wastewater treatment cost.

Description

technical field

[0001] The application relates to the field of wastewater treatment, in particular to a bioreactor for treating high-salt organic wastewater based on compound salt-tolerant bacteria. Background technique

[0002] With the development of my country's industrial technology, the problem of water resource utilization and treatment is becoming more and more serious. Conventional industrial wastewater is usually treated with pretreatment + activated sludge method + advanced treatment, and the treated wastewater is discharged or reused up to the standard. For the treatment of high-salt wastewater, evaporative crystallization or membrane treatment technology is generally used to extract the salt in wastewater, and then treated by ordinary activated sludge method; or directly use salt-tolerant strains without pretreatment, and use activated sludge method to process.

[0003] The main disadvantages of the above-mentioned treatment of high-salt wastewater are: The exis...
