Combined double-vortex efficient muddy water purification device

Abstract

The invention discloses a combined double-vortex efficient muddy water purification device. The device comprises a vertical independent tank which is provided with a water outlet, a water inlet and a mud outlet; a water distribution unit is arranged in the tank of the purification device, and is composed of a sludge gathering area, a mixing area, a push-type reaction area, a clarification and sedimentation area and an inclined-tube sedimentation area from bottom to top; a path from the water inlet to a coarse granular sludge gathering area of the sludge gathering area is additionally provided with a hydraulic mixing desanding chamber which is internally provided with filler for mixing water with drugs; and a water inlet of the hydraulic mixing desanding chamber is equipped with a fluid distribution unit enabling fed water to rotate. The device disclosed by the invention can overcome the defects in the prior art well, save the occupied space and improve the work efficiency, and has a remarkable water purification effect.

Description

technical field [0001] The invention relates to industrial circulating water treatment equipment, in particular to a combined double-swirl flow high-efficiency turbid water purification device. Background technique [0002] The conventional treatment method of industrial circulating water is mainly according to vertical flow sedimentation (the first mixed sedimentation sand removal) and subsequent coagulation, flocculation, dosing and stirring, reaction, sludge return, inclined tube sedimentation and sludge discharge treatment The process is arranged horizontally or two or three of them are combined, and its disadvantage is that it needs more tanks (in order to complete multiple process procedures, it is composed of multiple vertical or horizontal tanks), and it occupies a large area. , complex operation, high investment, high operating costs and high power consumption. The treatment effect of vertical flow sedimentation is generally poor, especially the mixing and sand rem...

Problems solved by technology

[0002] The conventional treatment method of industrial circulating water is mainly according to vertical flow sedimentation (the first mixed sedimentation sand removal) and subsequent coagulation, flocculation, dosing and stirring, reaction, sludge return, inclined tube sedimentation and sludge discharge treatment The process is arranged horizontally or two or three of them are combined, and its disadvantage is that it needs more tanks (in order to complete multiple process procedures, it is composed of multiple vertical or horizontal tanks), and it occupies a large area. , complex operation, high investment, high operating costs and high power consumption

The treatment effect of vertical flow sedimentation is generally poor, especially the mixing and sand removal effect of vertical flow sedimentation is not good, which increases the processing burden of subsequent processes and directly affects the quality of effluent

[0003] For this reason, the applicant has carried out thorough improvement to the turbid water purification device, as Chinese patent ZL2011201302369 has announced a kind of high-efficiency combined water purifier, and it has made fundamental changes in the design of the water distributor, in the water purifier The sludge accumulation area, reaction area, clarification sedimentation area and inclined tube sedimentation area, etc. are integrated in the internal integration. Its use efficiency is high. The operating cost is low, but there are still some defects: first, before the sewage enters the equipment, the first sedimentation of large particles must be completed, so a tank to complete the process is required. Therefore, relatively speaking It also needs to occupy more space; secondly, in order to collect sludge more efficiently, a sludge return device is set between the sludge accumulation area and the primary mixing reaction area, including a sludge return pump installed in the device , the setting of the sludge return pump will undoubtedly consume more electric energy due to electric drive, which is not conducive to energy saving and environmental protection
