Embodiment 1

[0099] A high-concentration organic wastewater, the water quality indicators of the wastewater are: COD concentration is 11300mg / L, TN concentration is 2450mg / L, NH4 + -N concentration is 1689mg / L, and a kind of high-concentration organic wastewater treatment method provided by the present invention is used for processing:

[0100] Step 1: High-concentration organic wastewater enters the grid to remove large-volume pollutants, and then enters the regulating tank, where the water quality is mixed uniformly and the water volume is adjusted through the regulating tank. The mesh diameter of the coarse grid is 50mm, and the mesh diameter of the fine grid is 10mm;

[0101] Step 2: The effluent of the regulating tank is lifted to the mixing tank by the lifting pump of the regulating tank, and in the mixing tank, the mixed liquid at the end of the returning aeration tank, the returning sludge of the sedimentation tank and the high-concentration organic wastewater are mixed , and the ...

Abstract

The invention discloses a high-concentration organic wastewater treatment system and a method. The system comprises a mixing tank, wherein a nutrient solution and a carbon source are added into the mixing tank, and the mixing tank is used for mixing upstream sewage to be treated, the nutrient solution and the carbon source; a biological reaction device which is arranged at the downstream of the mixing tank, wherein a bacillus microbial film is attached to a carrier of the biological reaction device, and the biological reaction device is used for preliminarily removing COD, NH4<+>-N and TN in the to-be-treated sewage; an aeration tank which is arranged at the downstream of the biological reaction device, wherein a nutrient solution and a carbon source are added into the aeration tank, florataking bacillus microorganisms as dominant strains is added into the aeration tank, and the flora is used for removing residual COD, NH4<+>-N and TN in the to-be-treated sewage; and an aeration mechanism which is used for providing required dissolved oxygen for the aeration tank and purging a carrier of the biological reaction device. The method is implemented based on the system. The construction cost and the to-be-treated sewage treatment cost are reduced, and it can be guaranteed that effluent obtained after high-concentration organic wastewater is treated reaches the standard required bysubsequent treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-concentration organic wastewater treatment system and treatment method. Background technique [0002] With the rapid development of industry, the types and quantities of industrial wastewater have increased rapidly, and the pollution of different types of industrial wastewater to water bodies has become increasingly widespread and serious, eventually threatening human health and safety. Therefore, efficient treatment of industrial wastewater can effectively reduce environmental hazards and promote the healthy development of human beings. At present, industrial wastewater is mostly high-concentration organic wastewater. High-concentration organic wastewater refers to wastewater with high concentrations of COD, ammonia nitrogen, and total nitrogen discharged from landfill leachate, papermaking, leather, slaughtering, breeding, printing, and food industries. . High...
