Problems solved by technology

Based on the classic DLVO coagulation mechanism, the stirring speed and stirring time used in the mixing and flocculation stages of the traditional coagulation process are different, which increases equipment and infrastructure investment to a certain extent, and also due to different control conditions in a certain increased operating costs

example 1

[0015] Raw water passes through the water inlet constant flow control system. According to the influent water volume and raw water quality, the banana peel water treatment agent is added to the water inlet pipe next to the flocculation tank by a dosing pump, and then enters the flocculation tank at the same time as the water. The flocculation tank is a grid flocculation tank. In the pool, the flow velocity at the beginning is controlled to be 0.65 m / s, and the effective flocculation time is controlled to be 25 minutes. After the flocculation is completed, it enters the sedimentation tank, and the effective sedimentation time is controlled to be 40 minutes.

example 2

[0017] Raw water passes through the water inlet constant flow control system. According to the influent water volume and raw water quality, the banana peel water treatment agent is added to the water inlet pipe next to the flocculation tank by using a dosing pump, and then enters the flocculation tank at the same time as the water. The flocculation tank is a mechanical flocculation tank. , the initial speed control is 90 rpm, the initial time control is 6 minutes, the continuous speed control is 60 rpm, and the continuous time control is 15 minutes. After the flocculation is completed, it enters the sedimentation tank and controls the effective sedimentation time. for 40 minutes.

example 3

[0019] The raw water passes through the water inlet constant flow control system. According to the influent water volume and raw water quality, the banana peel water treatment agent is added to the water inlet pipe next to the flocculation tank by the dosing pump, and then enters the flocculation tank at the same time as the water. The flocculation tank is a folded plate flocculation tank. Pool, the flow velocity at the beginning is controlled to be 0.5 m / s, and the effective flocculation time is controlled to be 20 minutes. After the flocculation is completed, it enters the sedimentation tank, and the effective sedimentation time is controlled to be 45 minutes.

Abstract

The invention provides a coagulation technology of a banana skin water treatment agent and without a mixing process. A liquid product prepared through the national invention patent, namely a preparation technology of banana skin high-molecular coagulant for water treatment (201610245449.3) serves as a coagulant in the coagulation process. Compared with a traditional coagulation technology, on the premise that the amount of treated water is the same, the equipment cost, capital construction cost and operation cost can be reduced, and the technology can be used in the treatment field of various kinds of surface water, contaminated underground water and industrial wastewater or domestic sewage.

Description

technical field [0001] The invention belongs to a water treatment process, in particular to a coagulation process of a banana peel water treatment agent without a mixing process. Background technique [0002] The coagulation process refers to adding a coagulant to the water in the process of water supply or sewage treatment, so that the coagulant and water are mixed, so that the colloidal substances or fine suspended matter in the water are condensed into flocs, and then the mud and water are separated to complete The process of pollutant removal. The flocs produced by the coagulation process have strong adsorption force, which can not only adsorb suspended solids, but also adsorb some bacteria and dissolved substances. Therefore, as an important traditional process, the coagulation process has the advantages of convenient operation, simple equipment, good effect and convenient intermittent operation. Therefore, it is still one of the most extensive and important applicatio...
