Description

Sewage treatment integrated equipment Technical Field The utility model relates to integrated equipment for sewage treatment, in particular to integrated equipment for treating sewage of a chemical industry park containing more ammonia nitrogen and organic matters. Background The chemical industry is a ubiquitous industry worldwide, and has large sewage output and difficult treatment. The sewage treatment requirement of the chemical industry park widely exists, so that not only is sewage generated in a chemical industry park stably treated for a long time, but also the sewage pollution of the sporadic chemical industry park needs to be treated at any time. When small-scale and sporadic pollution is treated, the integrated treatment equipment has good application value by virtue of the advantages of rapidness in treatment and convenience in operation. Ammonia nitrogen and various organic matters are important components in sewage of chemical industry parks because the ammonia nitrogen and various organic matters are common chemical raw materials. Chemical industrial park sewage is not suitable for biological treatment because toxic substances are often contained in the sewage, and even if microorganisms can adapt to survival, the treatment efficiency is low. Compared with biological methods, chemical methods are more applicable. Most of organic matters in the sewage of the chemical industry park belong to refractory organic matters, and are treated by an advanced oxidation method, specifically comprising Fenton, ozone oxidation and the like. Although advanced oxidation has a strong oxidizing ability, the oxidizing efficiency for ammonia nitrogen is very limited. Disclosure of utility model In order to overcome the defects, the utility model aims to provide the integrated sewage treatment equipment for removing organic matters and ammonia nitrogen in the sewage of the chemical industry park by adopting a mode of combining ozone oxidation and sodium hypochlorite oxidation. To achieve the above object, the present utility model provides an integrated sewage treatment apparatus comprising: the device comprises a box body, wherein an equipment room and a reaction room are arranged in the box body; an ozone generating device, a sodium hypochlorite solution storage tank and a control device are arranged in the device chamber; The reaction chamber is divided into an ozone reaction chamber and a chlorination reaction chamber which are communicated end to end through a partition board; The head of the chlorination reaction chamber is provided with a sodium hypochlorite solution water distribution pipe, and the tail of the chlorination reaction chamber is provided with a drain pipe; The ozone generating device comprises an ozone generator and an ozone dissolved air tank, wherein ozone generated by the ozone generator enters the ozone dissolved air tank through a pipeline; The water inlet of the ozone dissolved air tank is provided with an ozone dissolved air water pipe which is used for pumping clean water at the position close to a drain pipe of the chlorination reaction chamber into the ozone dissolved air tank, and the water inlet of the ozone dissolved air water pipe is lower than the drain pipe; The sodium hypochlorite solution water distribution pipe is communicated with the sodium hypochlorite solution storage tank through a pipeline. Further, the raw water distribution pipe is positioned at the lower part of the ozone reaction chamber. Further, the water flow directions of the ozone reaction chamber and the chlorination reaction chamber are lower inlet and upper outlet. Further, the effluent above the tail of the ozone reaction chamber enters the chlorination reaction chamber from below the head of the chlorination reaction chamber after passing through a pipeline or a channel. The utility model has the following advantages: (1) The integrated equipment adopts a combined process of ozone oxidation and sodium hypochlorite oxidation, so that sewage containing more ammonia nitrogen and organic matters in the chemical industry park can be efficiently treated. (2) All the devices are integrated in the cuboid box body, so that the appearance is concise and attractive, and the operation is simple. (3) And the ozone oxidation process is followed by a sodium hypochlorite oxidation process, and the sodium hypochlorite has a decomposition effect on ozone, so that tail gas pollution is reduced.
