Embodiment 2

[0041] A micro-vortex flocculation inclined tube sedimentation water treatment method based on sludge water reuse, including the following steps. The specific operating parameters are shown in Table 1:

[0042] 1 Micro vortex flocculation: Raw water is input into static pipeline mixer 2 through water inlet pipe 1, and coagulant is added at the same time, and raw water and coagulant are fully mixed in static pipeline mixer 2 to obtain reaction water 1; after that, the mixed solution passes through The water distribution bell mouth 3 evenly distributes water into the vortex reaction tank 4, and the coagulation reaction is strengthened through the regular hexagonal vortex reactor 5 in the vortex reaction tank 4, and the reaction water 2 and sludge 1 are obtained; after that, the reaction solution 2 is turned into the transition section 6. The sludge 1 sinks into the sludge hopper 10 of the reaction tank set under the vortex reaction tank 4; the regular hexagonal vortex reactor 5 n...

Abstract

The invention provides a micro-vortex flocculation and inclined pipe sedimentation water treatment device based on sludge water reuse. The device is characterized in that the device mainly comprises three constituent units which are a micro-vortex enhanced coagulation and inclined pipe sedimentation unit, a sludge water collection and sedimentation unit and a sludge water reuse unit. The inventionalso provides a micro-vortex flocculation and inclined pipe sedimentation water treatment method based on sludge water reuse. The method comprises the following steps: micro-vortex flocculation, inclined pipe sedimentation, sludge water collection and sedimentation, and sludge water reuse. The device and the method have the following advantages: the sludge water reuse and a micro-vortex reactionare organically combined to adapt to various water quality changes, so the impact load resistance is enhanced; and little change is carried out on the basis of the original water treatment structure in a water plant, so the water yield is increased, the quality of effluent water is improved, and the problem of sludge water treatment in the water plant is solved, thereby many things are achieved atone stroke.

Description

technical field [0001] The invention belongs to the field of environmental protection, and relates to a water treatment method for improving the coagulation reaction and sedimentation effect based on the reflux of sludge discharge water, in particular to a micro-vortex flocculation inclined tube sedimentation water treatment device based on the reuse of sludge discharge water from a water purification plant and its processing methods. Background technique [0002] With the continuous growth of population, people's demand for water resources is also increasing. The subsequent water supply plants will inevitably produce a large amount of production wastewater when producing water, mainly including sludge discharge from sedimentation tanks and backwash wastewater from filters, accounting for 4%-7% of the total production of water plants. [0003] It turns out that most water plants use the method of directly discharging sludge into rivers and lakes. However, sludge discharge c...
