Therefore, referring to fig. 2 to 11, in order to achieve uniform discharge of the flocculant, the distributed domestic water disinfection and purification apparatus is further provided with a material throwing barrel 10, a material blocking plate structure 6, a first sliding rail 2 and an adjusting assembly 7.

In order to realize the dispersion input of the flocculating agent, the material throwing barrel 10 is positioned above the flocculating barrel 12, the material throwing barrel 10 is of a hollow barrel structure, the flocculating agent in the material throwing barrel is controlled to be thrown out along the circumferential direction by utilizing centrifugal force during rotation, and the centrifugal material scattering device ensures that the flocculating agent is thrown out from the center to the periphery and falls into the flocculating barrel 12 in a dispersed state.

The distributed domestic water is a miniaturized and modularized water consumption mode which is independent of a centralized water supply and drainage pipe network in a city and independently completes water taking, treatment, water consumption and tail water treatment at nearby water consumption points. The water quality fluctuation of the water point is large, for example, the low turbidity water is used in the winter dead water period, the suspended particles are few, the flocculant dosage is small, and the high turbidity water is used in the rainy mountain torrent period, so that the flocculant dosage is greatly increased. The addition amount of the flocculant is required to be manually adjusted according to the water quality, and the experience of professionals is highly relied on, but the dispersive characteristic leads to that most workers are non-professionals and lack professional regulation and control capability, so that the addition amount of the flocculant is difficult to adapt to scenes. The following describes in detail two discharge modes of the storage assembly 4 to accommodate the flocculant dosage distinction between winter dead water and rainy mountain flood.

As in fig. 13, two modes of operation of the oscillating assembly 5 are described herein in the (a) state in fig. 13 and the (B) state in fig. 13:
