Problems solved by technology

[0006] The known problems that cannot be solved by the known technology are: during the operation of the clarifier, the flow state of the dosing seawater in the mixing reaction zone of the clarifier is often poor, the flow distance of the seawater is too short, and the degree of mixing with the return sludge Insufficient, resulting in insufficient concentration of the suspended sludge layer in the clarifier, and it contains more fine alum flowers
In this way, the purification effect of the clarification tank, which is based on the collision and growth of the tiny alum flowers generated by the sea water with the flocculant and the suspended mud layer sludge in the tank, is poor.
The operating load of the clarification tank does not meet the design requirements, and the effluent quality is poor, which increases the treatment load of the subsequent filtration process

Abstract

The invention provides a seawater clarifier turbulence construction and a clarifier thereof, relating to the technical field of seawater purifying treatment, in particular to the clarifier which improves the turbulence construction. The clarifier comprises a clarifier body composed of a first reaction chamber and a second reaction chamber and an agitating vane, wherein, the turbulence construction comprises a first turbulence unit and a second turbulence unit, the first turbulence unit is arranged in the first reaction chamber of the clarifier, and the second turbulence unit is arranged in the second reaction chamber of the clarifier. The seawater clarifier of the invention can improve flocculation condition effectively and improve the collision probability of destabilized small colloid in seawater, and the formed alumen ustum has better effect in size and settling property, thus achieving the purpose of improving the efficiency of water treatment.

Description

technical field [0001] This case involves the technical field of seawater purification and treatment, especially the clarifier with improved flow-disturbing structure. Background technique [0002] At present, the seawater purification treatment reaction clarifier relies on the sedimented sludge to circulate, and uses the sludge with flocculation activity to contact flocculation with seawater added with flocculants to improve the effect of seawater flocculation and sedimentation. [0003] For example, the published Chinese patent application 200710038625.7 is a high-efficiency clarified water treatment device and process belonging to the technical field of water treatment, specifically a high-efficiency clarified water treatment device and process. The middle part of the device is two volume flocculation chambers, which are equipped with a mesh spoiler, and the lower part of the volume flocculation chamber is a pre-sedimentation chamber. The active sludge suspension layer i...
