Embodiment 1

[0019] Embodiment 1, vortex grid clarifier, it comprises flocculation reaction unit, clarification unit and sludge thickening unit, wherein: the first vortex reaction chamber 5 and the second vortex reaction chamber 6 jointly form flocculation reaction unit, the bottom of vortex clarification tank The inlet pipe 12 of the water inlet pipe 12 communicates with the bell mouth at the bottom of the first vortex reaction chamber 5 successively through the nozzle 9, the throat pipe 8; Communication; a vortex grid flocculation reactor 13 is provided in the first vortex reaction chamber 5 and the second vortex reaction chamber 6; the operating rod 1 arranged on the top of the pool controls the vertical rise and fall of the throat pipe 8 through the connecting piece.

Embodiment 2

[0020] Embodiment 2, a clarification method for improving coagulation reaction and sedimentation effect in water treatment, the water that adds coagulant flows through pipeline mixer and enters from the water inlet pipe 12 at the bottom of the vortex clarifier, and then passes through nozzle 9, throat Tube 8 flows into the bell mouth of the first vortex reaction chamber 5 bottom;

[0021] After the water distribution is completed at the bell mouth, it enters the first vortex reaction chamber 5 and the second vortex reaction chamber 6. With the help of the device 13, the flocculation is completed, and the water flows out to the buffer zone 7 from the bottom of the second reaction chamber;

[0022] The floc sediment produced in the flocculation process sinks to the sludge area 10 located below the buffer zone 7 due to gravity, and the water flow passes through the inclined tube or the inclined plate area 4, and then the solid-liquid separation is further performed to complete th...

Embodiment 3

[0023] Embodiment 3. The vortex grid flocculation reactor 13 installed in the first vortex reaction chamber and the second vortex reaction chamber is a hollow sphere with grid-like holes on the spherical surface, and the opening ratio is 50% to 70%. All the other are with embodiment 1 or 2.

Abstract

The invention belongs to the field of environment protection, relates to a vortex grid clarifying pool and a clarifying method enhancing clarifying effect of coagulation reaction in water treatment. The pool comprises a flocculation reaction unit, a clarifying unit and a sludge concentration unit, wherein the flocculation reaction unit comprises a first vortex reaction chamber and a second vortexreaction chamber, a water inlet pipe at bottom of the vortex clarifying pool communicates with a bell mouth at bottom of the first vortex reaction chamber; the first vortex reaction chamber communicates with the second vortex reaction chamber, and the second vortex reaction chamber communicates with a buffer; vortex grid flocculation reactors are disposed in the first vortex reaction chamber and the second vortex reaction chamber; an operation rod disposed above the pool controls lifting on the longitudinal direction. The invention increases utility ratio of the first reaction chamber, reducesenergy consumption, capable of enhancing efficiency of flocculation reaction, reducing loss of water head and medicament consumption, enhancing quality of purified water, having relatively high social and economic effect.

Description

Technical field: [0001] The invention belongs to the field of environmental protection, and relates to a vortex grid clarification tank and a clarification method for improving coagulation reaction and sedimentation effect in water treatment. Based on pool theory. Background technique: [0002] The clarifier is a structure that integrates the flocculation reaction process and the clarification and separation process. At present, many clarifiers commonly used in my country's water treatment are facing problems such as aging, low water production efficiency, and poor effluent quality. For example, the mechanical agitation clarifier with a large amount of treated water has the disadvantages of large area, high civil construction cost, unstable operation, troublesome mechanical investment and maintenance; the hydraulic circulation clarifier is difficult to control because of the return flow of mud and slag, and the reaction The room volume is small, the reaction time is short,...
