High-speed coagulation reactor for feed water treatment

Abstract

The invention particularly relates to a high-speed coagulation reactor for feed water treatment. The high-speed coagulation reactor for feed water treatment comprises a reactor tank body, a water inlet pipe and a water outlet pipe. An L-shaped feeding pipe is arranged on the upper portion of the reactor tank body. Meanwhile, a stirrer and a flow disturbing cylinder are further arranged inside the reactor tank body. The stirrer is arranged in the center of the reactor tank body and connected to a motor through a speed reducer. The flow disturbing cylinder is fixed to the top end of the reactor tank body and located between the stirrer and the reactor tank body. The water inlet pipe and the water outlet pipe are embedded into the outer walls of the left side and the right side of the reactor tank body correspondingly. The high-speed coagulation reactor for feed water treatment can improve the mixing rate, shorten the mixing time and improve the removal rate of organic matter through coagulating sedimentation, so that the follow-up flocculation effect, the sedimentation effect and the filtering effect are further improved, and the quality of water discharged from a filter chamber in the following period is remarkably improved; and meanwhile, the dosage of a coagulant can be further reduced, the volume of a mixing pool is reduced, and the operating cost and the engineering construction investment are reduced.

Description

technical field

[0001] The invention relates to the technical field of water treatment, in particular to a high-speed coagulation reactor for water treatment. Background technique

[0002] At present, most of the effluent turbidity of sedimentation tanks of water purification plants using conventional treatment processes in my country is 1 to 3 NTU, and the turbidity of effluent water from filters generally does not exceed 1 NTU; while the turbidity of effluent water from sedimentation tanks of foreign advanced water purification plants using similar processes The turbidity of the filter water is not higher than 1NTU, and the turbidity of the filter water is not higher than 0.1NTU. It can reach the standard of direct drinking water without advanced treatment. However, after the domestic conventional treatment process, it is necessary to increase the advanced treatment of membrane filtration to make the turbidity of the water supply reach a level not higher than 0.1NTU.
