Embodiment 1

[0055] 1. After the ammonia distillation treatment, the effluent is pumped to the adjustment tank by the ammonia distillation effluent pump. The raw water quality: pH is 7.8, COD is 2250mg / l, phenol is 65mg / l, ammonia nitrogen is 220mg / l, oil is 16mg / l , T-CN is 12mg / l, and the water temperature is 28°C.

[0056] 2. The effluent from the adjustment tank is pumped to the anoxic tank through the transfer pump, and the water in the anoxic tank is treated with two parts: one part is the effluent from the adjustment tank, and the other part is the reflux mixture from the aerobic tank. The ratio of the effluent from the adjustment tank to the reflux mixture is 1:3, the effluent from the anoxic tank overflows to the aerobic distribution tank.

[0057] 3. The effluent from the anoxic tank flows into the aerobic distribution tank through the overflow, and the special-effect carrier and pure water are mixed into a slurry with a concentration of 10% through the powder dosing device, and ...

Abstract

The invention provides a biological carrier for treating coking wastewater biochemical systems. The biological special-effect carrier comprises the following components in percentage by mass: 25-40% of activated carbon A, 25-40% of activated carbon B, 20-45% of diatomite and 5-40% of slag micropowder. The invention also provides application of the biological carrier in the aspect of enhancing coking wastewater biochemical system treatment capacity. The adsorbent is a combination of different types of activated carbon with slag micropowder and diatomite, can adsorb the pollutants in different molecular structures in wastewater more efficiently, enhances the adsorption efficiency of single activated carbon, and can enhance the coking wastewater treatment capacity.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a coking waste combined water treatment agent, and to the specific application of the treatment agent. Background technique [0002] Coking wastewater is the wastewater formed during high-temperature and medium-temperature dry distillation of coal, gas purification and chemical product refining, which contains organic pollutants such as phenols, benzene series, polycyclic aromatic hydrocarbons, and nitrogen-containing heterocyclic compounds, as well as ammonia, cyanide, sulfur, etc. Inorganic pollutants such as cyanide have complex components, a wide variety of components, high concentration of organic pollutants and high chroma of sewage, high toxicity, and very stable properties. It is a typical refractory complex toxic industrial organic wastewater. It is difficult and costly to meet the discharge standards. If the treatment is not done properly, it will cause great harm t...
