Embodiment Construction

[0016] Below in conjunction with specific embodiment, further illustrate the present invention.

[0017] As shown in the figure, the water added with coagulant flows through the tubular mixer 2 from the water inlet pipe 1 and flows through the first flap vortex reaction chamber 5, the second flap vortex reaction chamber 6, the third flap vortex reaction chamber 7 and the third flap vortex reaction chamber. The four-fold plate vortex reaction chamber 8, the first folded plate vortex reaction chamber 5 and the second folded plate vortex reaction chamber 6 are all different folded plates, and a type I vortex reactor 4 is placed inside; the third folded plate vortex reaction chamber 7 The fourth folded plate vortex reaction chamber 8 is the same folded plate, and a type II vortex reactor 10 is placed in it at the same time. After the water flow passes through the folded plate and the vortex reactor, countless small eddies are formed, which makes the quality of the floc alum flower...

Abstract

The invention discloses a precipitation water treatment method. The method involves a folded plate eddy current synergistic flocculation unit, an inclined pipe precipitation unit, a sludge backflow and discharge unit and a dredge pipe backwash unit, wherein the folded plate eddy current synergistic flocculation unit is composed of four folded plate eddy current reaction chambers, raw water enters an water inlet pipe, passes through a pipeline mixer, and orderly passes through the four folded plate eddy current reaction chambers via a pipe mixer, and then enters the inclined pipe precipitation unit after passing through a transition area; same-wave folded plates, opposite folded plates and eddy current reactors in different models are arranged in the four folded plate eddy current reaction chambers, and a sludge backflow, discharge and backwash device unit is arranged at the bottom of each of the four folded plate eddy current reaction chambers. By use of the method disclosed by the invention, the efficiency of the flocculation reaction is improved, the effects of improving the water purification amount and the water quality are obvious, and the clarifying efficiency and the precipitation effect are guaranteed at the same time, water sources and the coagulation reagent quantity are effectively saved, and the high social and beneficial benefit are realized.

Description

technical field [0001] The invention belongs to the field of environmental protection, and relates to a folded plate eddy current cooperative flocculation and inclined tube sedimentation water treatment method. It is proposed based on the theory of vortex synergistic coagulation technology, shallow pool theory and sludge return enhanced coagulation theory. Background technique [0002] At present, my country's urban water supply industry is facing the dual pressure of water source water quality pollution and water supply quality standard improvement. In addition, the difficulty of drinking water has plagued my country's rural areas and some townships for a long time, seriously restricting the improvement of local residents' living conditions and the development of rural economy. Solving the safety of drinking water in rural areas and some towns is a livelihood project that the Party Central Committee and the State Council attach great importance to and that is urgently neede...
