Embodiment

[0023] The embodiment discloses a high-concentration refractory organic wastewater treatment process, combining figure 1 , including the following 6 steps:

[0024] S1, the waste water is imported into the adjustment pool for homogeneous and equal quantity adjustment, and then sent into the heating pool to heat the organic waste water, and the heating temperature is 55 ° C to 60 ° C;

[0025] Through the heating treatment of high-concentration refractory organic wastewater, the toxic and harmful substances in the wastewater are hydrolyzed, destroying the toxic components that are harmful to microorganisms, and reducing the toxicity of wastewater;

[0026] S2. Adjust the pH range of the wastewater to 1~2, and the wastewater enters the integrated iron-carbon Fenton pool: first enters the iron-carbon pool for iron-carbon reduction electrolysis, and the ratio of iron filings and carbon in the iron-carbon pool is 1:1 by volume , the total amount of filling is 60% to 80% of the eff...

Abstract

The invention discloses a high-concentration degradation-resistant organic wastewater treatment process. The process comprises the following steps of: (1) carrying out homogeneous average adjustment and heating treatment; (2) treating in an all-in-one iron carbon Fenton tank; (3) treating in a two-phase two-stage anaerobic tank; (4) carrying out sludge sedimentation in a sedimentation tank; (5) carrying out biological degradation in a biological oxidation tank; and (6) further removing contaminants in a floatation tank. According to the treatment process, the respective advantages of an advanced oxidation process and a biochemical process are fully combined, high-concentration degradation-resistant organic wastewater can be purified stably, economically, safely and efficiently; and besides, the process is low in investment cost, floor area and operating cost.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a high-concentration refractory organic waste water treatment process. Background technique [0002] At present, my country's textile, papermaking, pharmaceutical, chemical and other industries are still the country's "big polluters". The high-concentration refractory organic wastewater discharged has caused serious pollution to major water systems across the country, causing great harm to human health and ecological pollution. The environment has caused huge damage, so the demand for comprehensive treatment of high-concentration refractory organic wastewater in industries such as textiles, papermaking, pharmaceuticals, and chemicals, and new processes and technologies for water reuse will inevitably increase. Treatment process technology research and screening optimization are also major issues in the treatment of industrial pollution sources. At present...
