Embodiment 1

[0051] like figure 1 The wastewater in a chemical park shown in the figure flows through the regulating tank, the electroflocculation system, the air flotation system, the intermediate tank, the ozone catalytic reaction tower, the oxidation stabilization tank, the aerated biological filter, the inclined plate sedimentation tank, and the clean water after the secondary biochemical treatment. Pool, filter cloth filter, ultraviolet disinfection pool, carry out advanced treatment, and then discharge to the first-level A emission standard.

[0052] First, the secondary biochemical effluent enters the conditioning tank 1, and the liquid caustic soda is stored in the liquid caustic storage tank. It is added to the conditioning tank 1 through the liquid alkali dosing pump 1, and an agitator is installed in the conditioning tank 1 to achieve sufficient liquid alkali and wastewater. Mixing, the pH meter 1 is set in the adjustment tank 1, the pH value signal is input to the controller, t...

Abstract

The invention relates to the field of environmental engineering sewage treatment, in particular to an advanced treatment process for chemical industry park wastewater. Directed at the secondary biochemical effluent from chemical industry park sewage plants, the process utilizes electric flocculation and air flotation for pretreatment to separate suspended matters, the separated wastewater is subjected to ozone catalyzed oxidation decomposition and destruction of heterocyclic hardly degradable organic matters in wastewater, and the wastewater chroma is lowered, then the wastewater enters a biological aerated filter system for biological enhanced treatment, and the treated effluent enters a clean water tank, thus finally realizing discharging meeting the first level standard A. The advancedtreatment process is economical and feasible, and provides a reliable, efficient and stable combination technology for advanced treatment of chemical industry park wastewater.

Description

technical field [0001] The invention relates to the field of environmental engineering sewage treatment, in particular to a process method for advanced treatment of waste water in chemical industrial parks. Background technique [0002] The chemical industry park is the product of the modern chemical industry in order to adapt to the transformation of resources or raw materials, and conform to the development trend of large-scale, intensified, optimized, internationalized operations and maximized benefits. At present, with the continuous development of China's industrial economy and industry, a park-based development model has gradually formed, followed by the environmental problems caused by the gradual increase in the amount of sewage in the park and the particularity of the water quality in the park. The wastewater discharged by the chemical park has the following characteristics: [0003] (1) There are many chemical production devices in the chemical park, the discharge ...
