Abstract

The invention provides an alternative hydrolysis pretreatment device and a method for treating wastewater by using the device. The alternative hydrolysis pretreatment device comprises a water inlet connected with a water pump; the water pump is respectively connected to a water inlet zone of a hydrolysis tank A and a water inlet zone of a hydrolysis tank B through pipelines; the outlet of the hydrolysis tank A is respectively connected to the water outlet and the water inlet pipe an upflow anaerobic sludge bed reactor through pipelines; the outlet of the hydrolysis tank B is respectively through pipelines connected the water outlet and the water inlet pipe of the upflow anaerobic sludge bed reactor; and the water outlet pipe of the upflow anaerobic sludge bed reactor is respectively connected to the water inlet zone of the hydrolysis tank A and the water inlet zone of the hydrolysis tank B through pipelines. The invention has the advantages of simple structure, convenient connection and easy switching, and can prolong the survival life of the microorganism, improve the processing efficiency of the pretreatment system, and realize the two purposes in one device.

Description

Technical field [0001] The invention relates to an alternative biological hydrolysis pretreatment device for treating high-concentration organic wastewater that is difficult to degrade and a method for treating wastewater by using the device. Background technique [0002] With the development of China's modernization, the chemical industry occupies a pivotal position, such as chemical pharmacy and paint. The chemical raw materials used in these industries are often biologically toxic. The wastewater concentration in the work section is extremely high, and the chemical requirement (COD) is even as high as 10,000 mg / L. This type of wastewater usually requires advanced oxidation to change the structure of organic matter in the wastewater. When it is reduced to 5000mg / L, perform anaerobic-aerobic process. [0003] However, in engineering, the COD concentration and toxicity of wastewater are often further increased during operation errors and shutdown start-up phases. For this type of...
