Embodiment 1
[0031] A high-efficiency and energy-saving high-concentration sugar cane sugar wastewater treatment process, comprising the following steps:
[0032] The pollutant content of sugar wastewater influent water quality is: chemical oxygen demand COD is 11050mg / l, ammonia nitrogen content is 58.5mg / l, total phosphorus content is 18.0mg / l, and suspended solid content SS is 327mg / l.
[0033] (1) Pretreatment of sugar-making wastewater; sugarcane sugar-making wastewater passes through the grid to filter out large particles of suspended matter and floating matter, and the effluent of the grid enters the homogeneous pool for homogeneous treatment, and the effluent of the homogenized treatment enters the pretreatment pool and is sent to the pretreatment pool. Add sodium hydroxide powder to the pretreatment tank, adjust the pH to 7.0, and stir homogeneously; put in modified zeolite-Fe 3 o 4 Particles, adsorption treatment for 3h, pretreatment ends;
[0034](2) The pretreated effluent en...
Embodiment 2
[0045] A high-efficiency and energy-saving high-concentration sugar cane sugar wastewater treatment process, comprising the following steps:
[0046] The pollutant content of sugar wastewater influent water quality is: chemical oxygen demand COD is 11050mg / l, ammonia nitrogen content is 58.5mg / l, total phosphorus content is 18.0mg / l, and suspended solid content SS is 327mg / l.
[0047] (1) Pretreatment of sugar-making wastewater; sugarcane sugar-making wastewater passes through the grid to filter out large particles of suspended matter and floating matter, and the effluent of the grid enters the homogeneous pool for homogeneous treatment, and the effluent of the homogenized treatment enters the pretreatment pool and is sent to the pretreatment pool. Add sodium hydroxide powder to the pretreatment tank, adjust the pH to 7.3, stir homogeneously; put in modified zeolite-Fe 3 o 4 Particles, adsorption treatment for 3.5h, pretreatment ends;
[0048] (2) The pretreated effluent ent...
Embodiment 3
[0059] A high-efficiency and energy-saving high-concentration sugar cane sugar wastewater treatment process, comprising the following steps:
[0060] The pollutant content of sugar wastewater influent water quality is: chemical oxygen demand COD is 11050mg / l, ammonia nitrogen content is 58.5mg / l, total phosphorus content is 18.0mg / l, and suspended solid content SS is 327mg / l.
[0061] (1) Pretreatment of sugar-making wastewater; sugarcane sugar-making wastewater passes through the grid to filter out large particles of suspended matter and floating matter, and the effluent of the grid enters the homogeneous pool for homogeneous treatment, and the effluent of the homogenized treatment enters the pretreatment pool and is sent to the pretreatment pool. Add sodium hydroxide powder to the pretreatment tank, adjust the pH to 7.5, and stir homogeneously; put in modified zeolite-Fe 3 o 4 Particles, adsorption treatment for 4h, pretreatment ends;
[0062] (2) The pretreated effluent e...
