Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an improved built-in electrolysis device. Background technique [0002] Electrolysis is a commonly used method of phosphorus removal in sewage treatment equipment. This electrolytic phosphorus removal technology is to place the electrode plate in the electrolytic box, use an external DC power supply to the electrode plate, and release metal ions by sacrificial anodes, so that the metal ions or their hydrates and the phosphate in the water are integrally formed and precipitated. Closely remove phosphorus in water. [0003] In order to increase the amount of metal ions released by the anode, a polarizing plate can be added between the positive main electrode plate connected to the positive pole of the power supply and the negative main electrode plate connected to the negative pole of the power supply. The polarizing plate is on both sides of the positive main electrode plate and t...

Problems solved by technology

[0003] In order to increase the amount of metal ions released by the anode, a polarizing plate can be added between the positive main electrode plate connected to the positive pole of the power supply and the negative main electrode plate connected to the negative pole of the power supply. The polarizing plate is on both sides of the positive main electrode plate and the negative pole Under the potential generated by the main electrode plate, metal ions are released. The more the separator plates are, the more metal ions are released, and the phosphorus removal effect is better. The distance between the positive main electrode plate and the negative main electrode plate in the existing electrolytic box Fixed, the distance between the plates is too small, because a certain distance must be maintained between adjacent plates, it is impossible to add too many separator plates between the positive main electrode plate and the negative main electrode plate, for sewage with high phosphorus content , the phosphorus removal effect is not good. In order to ensure the electrolytic phosphorus removal effect, the distance between the positive main electrode plate and the negative electrode main electrode plate is generally designed according to the standard for removing sewage with high phosphorus content. The larger the distance between the negative main electrode plates, the higher the power consumption. At this time, when treating sewage with low phosphorus content, the electric energy will be wasted, and the phosphorus removal effect will not be improved; The number of polar plates in between is mostly fixed. When treating sewage with low phosphorus content, metal ions are released excessively, and the release of metal ions will consume the polar plates, which is a great waste of the polar plates.
