The invention belongs to the field of papermaking wastewater treatment, and relates to a papermaking wastewater pretreatment device which comprises a cylindrical first box body and a second box body fixedly installed on the side face of the first box body, and a coagulant storage tank is fixedly installed on a shell on the side, opposite to the direction of the second box body, of the first box body. A water inlet is formed in the side, close to the coagulant storage tank, of the top side of the first box body, a control motor is fixedly installed at the top of the second box body, and a discharging port is formed in the position, on the side opposite to the first box body, of a shell of the second box body, the first box body comprises a first shell, and a first motor is arranged at the top of the inner side of the first shell; a vertically downward control shaft is arranged below the first motor, a wastewater separation module is arranged on the control shaft and located below the water inlet, a treatment cavity is formed in the position, located below the wastewater separation module, of the first shell, a defoaming module is arranged on the control shaft and located in the treatment cavity, and a stirring rod is arranged on the control shaft and located below the defoaming module; and a compaction drainage module is arranged in the coagulant storage tank. A large amount of floating foam containing harmful substances generated in the papermaking wastewater cleaning process can be removed.
Description
technical field [0001] The invention belongs to the field of papermaking wastewater treatment, in particular to a papermaking wastewater pretreatment device. Background technique [0002] Papermaking wastewater refers to the wastewater generated during the pulp and papermaking process. Including pulping and cooking wastewater, washing wastewater, bleaching wastewater and paper machine white water, etc. Papermaking wastewater has complex composition and poor biodegradability. It is an industrial wastewater that is difficult to treat and is one of the main sources of industrial pollution in my country. [0003] During the cleaning process of papermaking wastewater, a large amount of scum containing harmful substances will be produced. The existing equipment is not thorough in cleaning the scum, and it is necessary to design a device that can completely remove the scum. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a papermaking wastew...
