The invention relates to an advanced treatment technology of high-concentration organic wastewater. The high-concentration organic wastewater is generally organic wastewater with complex pollutant ingredients and high chemical oxygen demand (COD); and the conventional high-concentration organic wastewater is mostly treated by adopting the conventional biochemical treatment process, so COD, suspended substance (SS) and chroma indexes of effluent hardly meets the requirements of 'Integrated Wastewater Discharge Standard'. To solve the problems, a ternary medicament and high-efficiency clarification technology is provided. The adopted technical scheme is that: (1) in unitary adsorption, the terminal adsorption of biochemical treatment is improved for soluble microbial products (SMP); (2) in binary oxidization, the oxidization before advanced treatment is improved for organic substances which are difficult to decompose; and (3) in ternary coagulation, a polymer coagulant and a high-density filter process are adopted for SS. The problem that the effluent of the high-concentration organic wastewater cannot reach standard is solved, the stability of the effluent is also ensured, and the standard discharge of the high-concentration organic wastewater is also realized.
Description
Technical field [0001] The invention relates to an invention patent for the advanced treatment technology of high-concentration organic wastewater after biochemical treatment. Background technique [0002] High-concentration organic wastewater generally refers to organic wastewater with complex pollutant components, high COD concentration, and high toxicity. It widely exists in various industries such as industry and municipal administration. Representative wastewater mainly includes feces wastewater, coal chemical wastewater, benzene chemical wastewater, Printing and dyeing wastewater, textile wastewater, papermaking wastewater, food processing wastewater, etc. High-concentration organic wastewater mainly contains inorganic substances such as ammonia, cyanide, and hydrogen sulfide, as well as phenol, benzene, naphthalene, pyridine, quinoline, anthracene, and other aromatic and fused-ring aromatic compounds, as well as oily substances. [0003] Most of the existing domestic...
