Embodiment 1

[0021] A method for advanced treatment of rubber-making wastewater, comprising the following steps:

[0022] (1) Regulating tank treatment: Wastewater enters the regulating tank, the hydraulic retention time is 8 hours, the temperature is 30°C, and the dissolved oxygen is controlled below 0.5mg / L;

[0023] (2) UASB anaerobic treatment: Wastewater enters the UASB anaerobic biochemical treatment unit, the dissolved oxygen is controlled below 0.2mg / L, the temperature is 30°C, and the hydraulic retention time is 5h;

[0024] (3) Anoxic pool treatment: Wastewater enters the anoxic pool treatment unit, the dissolved oxygen is controlled below 0.5mg / L, the temperature is 30°C, and the hydraulic retention time is 18h;

[0025] (4) Aerobic pool treatment: Wastewater enters the aerobic pool treatment unit, the dissolved oxygen is controlled at 3mg / L, the temperature is 35°C, and the hydraulic retention time is 4h;

[0026] (5) Microwave advanced treatment process: waste water enters th...

Embodiment 2

[0029] A method for advanced treatment of rubber-making wastewater, comprising the following steps:

[0030] (1) Regulating tank treatment: Wastewater enters the regulating tank, the hydraulic retention time is 12h, the temperature is 35°C, and the dissolved oxygen is controlled below 0.5mg / L;

[0031] (2) UASB anaerobic treatment: the wastewater enters the UASB anaerobic biochemical treatment unit, the dissolved oxygen is controlled below 0.2mg / L, the temperature is 35°C, and the hydraulic retention time is 8h;

[0032] (3) Anoxic pool treatment: Wastewater enters the anoxic pool treatment unit, the dissolved oxygen is controlled below 0.5mg / L, the temperature is 35°C, and the hydraulic retention time is 24h;

[0033] (4) Aerobic pool treatment: Wastewater enters the aerobic pool treatment unit, the dissolved oxygen is controlled at 5mg / L, the temperature is 38°C, and the hydraulic retention time is 8h;

[0034] (5) Microwave advanced treatment process: waste water enters th...

Embodiment 3

[0037] The difference between embodiment 3 and embodiment 2 is:

[0038] Step (6) is: the waste water is filtered through a filter screen, and the filtrate is passed through a mixture of D3520 macroporous adsorbent resin, AB-8 macroporous adsorbent resin and NKA-9 macroporous adsorbent resin (mass ratio 4:3:1), and the sample loading flow rate is The weight ratio of filtrate to macroporous adsorption resin is 7:1, and the ratio of resin column diameter to height is 1:8.

Abstract

The invention provides a deep treatment method of rubber wastewater. The method mainly comprises the following steps: (1) regulation pool treatment; (2) UASB anaerobic treatment; (3) anoxic pool treatment; (4) aerobic pool treatment; (5) microwave deep treatment; and (6) resin deep treatment. By adopting the method provided by the invention, the wastewater treatment time can be effectively shortened, and the treatment effect on the rubber wastewater is obvious, the SS removal rate reaches 85.6-93.2%, the COD removal rate reaches 99.1-99.7%, NH3-N removal rate reaches 93.0-98.2%, the TN removalrate reaches 93.7-99.2%, and the treatment method conforms to the primary standard of the NY687-2003 stipulation.

Description

technical field [0001] The invention relates to the technical field of natural rubber processing wastewater treatment, in particular to a method for advanced treatment of rubber manufacturing wastewater. Background technique [0002] A large amount of high-concentration organic wastewater is produced during the processing of natural rubber. The water quality is complex and the environment is seriously polluted. The main pollutants are COD, NH3-N, SS, etc. At present, the treatment method of natural rubber processing wastewater generally adopts anaerobic-aerobic method. The main procedures include: advection grit chamber, coagulation pond, facultative pond, primary aerobic contact oxidation pond, delayed biochemical pond, secondary Aerobic contact oxidation ponds, sedimentation ponds and filter ponds, etc., but this method is not only complicated in process, time-consuming, but also not ideal in effect. Contents of the invention [0003] In view of the deficiencies of the ...
