The electroflocculation tank includes a power board, a positive electrode, a negative electrode, Electrode plate and stirring device 2. The sedimentation tank includes a retaining wall, inclined pipe tank group, mud scraping device and water diversion tank. The denitrification tank is set on the right side of the sedimentation tank, and the disinfection reaction tank is set on the right side of the denitrification tank. The water outlet It is arranged on the right side wall of the main body, a residual chlorine detection device is arranged at the water outlet, and the PLC controller is arranged on the right side wall of the main body above the water outlet.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to an integrated denitrification filter of a charged flocculation device. Background technique [0002] Denitrification filter is an advanced sewage treatment technology that integrates denitrification biological denitrification and filtration functions. Its working principle is that when sewage flows through the filler inside the filter, the biofilm attached to the filler In the state, the nitrite and nitrate are reduced to nitrogen and other reducing gases; at the same time, under the physical interception and adsorption of the filler, a part of the influent suspended solids is also removed. [0003] In order to reduce the influent suspended solids content of the denitrification filter and prolong the backwash cycle of the filter, the pretreatment method of high-efficiency coagulation and sedimentation is usually used to remove most of the suspended ...

Problems solved by technology

At present, most of them use the combination process of ozone and biological treatment, such as: Chinese patent 201711447463.2 discloses a wastewater treatment system and method for ozone treatment and biofilter. The invention includes an ozone treatment device and a biofilter, which can effectively remove refractory waste water Organic matter, but the ozone content in the ozone-containing air stream is low, the amount of ozone required is large, the energy consumption is large, and the system cannot meet the requirements of deep denitrification
