Cell breaking device

Abstract

The invention discloses a cell breaking device which comprises an external electrode, and an internal electrode sleeved by the external electrode, and also comprises an electrode tip respectively electrically connected with the external electrode and the internal electrode; the external electrode is a stainless steel sleeve provided with a polytetrafluoroethylene layer at the outside. The device of the invention has a tubular structure, is free of moving part, is free from wearing, and needs no maintenance generally; the energy consumption for a sinlge device is 35 W, and the energy consumption is reduced; a DN150 pipe diameter is adopted, and thus the processing capacity is large.

Description

technical field [0001] The invention relates to a cell breaker. Background technique [0002] With the increasing eutrophication of water bodies, many countries have formulated increasingly stringent nitrogen and phosphorus discharge standards. However, most sewage plants operate in a low-carbon source environment, and when the carbon source is too low, the conventional anaerobic-anoxic-aerobic biological treatment process is often difficult to meet the requirements of efficient nitrogen and phosphorus removal at the same time. To further increase the removal rate of nitrogen, it is necessary to supplement the carbon source. However, due to the inherent nature of raw water, the amount of water to be treated is large, and the addition of carbon sources will inevitably increase the cost. Therefore, efficient nitrogen and phosphorus removal from raw water with low carbon sources has become an urgent problem to be solved in raw sewage treatment. [0003] However, a large amoun...
