Embodiment Construction

[0056] In order to better understand the present invention, the content of the present invention will be further clarified below in conjunction with the examples and accompanying drawings, but the present invention is not limited to the following examples.

[0057] like figure 1 As shown, the present invention transforms the reaction device of the coagulation process part of water supply treatment. The process flow is: raw water enters the mechanical coagulation tank 2 through the raw water inlet pipe 1, and flocculant is added, and the agitator 3 rotates rapidly to carry out water and Rapid mixing of medicaments is mixed with medicaments, and then enters the hydraulic flocculation tank, and enters the next process through the outlet pipe 11.

[0058] by figure 2 For example, an adjustable water treatment coagulation reaction system includes a mechanical mixing tank 2 and a hydraulic flocculation tank 7, and the height difference between the mechanical mixing tank 2 and the ...

Abstract

The invention discloses an adjustable novel water treatment coagulating reaction system adapting to the quality and quantity change of raw water. The system mainly comprises a mechanical mixing tank and a hydraulic flocculation tank, wherein the height difference between the mechanical mixing tank and the hydraulic flocculation tank is greater than the head loss between the mechanical mixing tank and the hydraulic flocculation tank; a circumferential surrounding type water-in canal is arranged on the periphery of the hydraulic flocculation tank, a water-out canal is arranged at the upper part, and a blow-down pipe and a mud discharge pipe are arranged at the bottom; the mechanical mixing tank is communicated with the circumferential surrounding type water-in canal through a connection pipeline; a valve is arranged on the connection pipeline; multiple water-in pipes are arranged at the bottom of the circumferential surrounding type water-in canal and form an angle with the horizontal direction; and multiple holes are formed in the water-in pipes. In the system disclosed by the invention, the G value can be adjusted according to the actual conditions of water quality and quantity and based on the structural characteristics of the device and in combination with the corresponding adjusting way so as to realize better coagulation effect and energy conservation; and the system brings good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of coagulation reaction device manufacture and application, in particular to a water treatment coagulation reaction system combining a mechanical mixing tank and a hydraulic flocculation tank that can adjust the speed gradient according to water quality and quantity. Background technique [0002] In the process of water supply treatment, the process from the uniform mixing of liquid medicine and water to the formation of large particle flocs is coagulation. Coagulation is composed of two parts: mixing and flocculation, which are all promoted by corresponding equipment. Among them, the basic requirement of mixing equipment is: the mixing of medicament and water must be fast and uniform. The basic requirements of the flocculation equipment are: After the raw water is mixed with the chemical agent, the large dense flocs visible to the naked eye should be formed through the flocculation equipment, so as to achie...
