Treatment equipment for refractory wastewater

Abstract

The invention discloses treatment equipment for refractory wastewater. The treatment equipment comprises a raw water pit and an inclined tube sedimentation tank, wherein a degradation pool is arrangedbetween the raw water pit and the inclined tube sedimentation tank; the raw water pit is communicated with the degradation pool; the degradation pool is communicated with the inclined tube sedimentation tank; a positive electrode plate is arranged on one side of the degradation pool; a negative electrode plate is arranged on the other side of the degradation pool; a packing material is arranged between the electrode plates on two sides; the wastewater can be continuously treated; the packing material is arranged between the negative electrode plate and the positive electrode plate; a plurality of small galvanic batteries and electrochemical reaction are formed between the negative electrode plate and the positive electrode plate under the action of an electrical field between the negativeelectrode plate and the positive electrode plate. An external power supply and the packing material form a plurality of batteries; organic pollutants in the wastewater are sufficiently decomposed byusing current; meanwhile, the treatment equipment is introduced with ozone, so that the oxidation efficiency is improved and the treatment effect is improved. The treatment equipment has the advantages of simple operation, small occupied area, good treatment effect and the like, as well as superiority which is incomparable by other methods.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a treatment equipment for refractory wastewater. Background technique [0002] Modern wastewater treatment technology can be divided into four categories according to its principle of action: physical method, chemical method, physical chemical method and biological treatment method. Various methods are used to separate the pollutants contained in the sewage or convert them into Harmless and stable substance, so that the sewage can be purified. At present, biochemical methods such as anaerobic-aerobic method and activated sludge method are mainly used in my country, but there are still obvious deficiencies, such as high infrastructure construction cost and operating cost, large floor area, long cycle, and treatment efficiency needs to be improved. Importantly, many refractory pollutants are difficult to remove by direct biochemical treatment, so degrading re...

Problems solved by technology

At present, biochemical methods such as anaerobic-aerobic method and activated sludge method are mainly used in my country, but there are still obvious deficiencies, such as high infrastructure construction cost and operating cost, large floor area, long cycle, and treatment efficiency needs to be improved. The important thing is that many refractory pollutants are difficult to remove directly by biochemical treatment, so degrading refractory macromolecular organics into small molecular organics will be a breakthrough in the treatment of refractory wastewater
