Description

Water purification device based on sand filtration

Technical Field

The utility model belongs to the technical field of urban water purifies, concretely relates to filter water purifier based on sand.

Background

Sources of contaminants in water include exogenous and endogenous pollution; exogenous pollution includes point source pollution (industrial sewage, domestic sewage, etc.) and surface source pollution (initial rainwater runoff, air dust fall, agricultural waste dumping, etc.); endogenous pollution includes the release of sludge and pollutants in the water body. The root cause of the black and odorous water body is that the pollution amount exceeds the self-cleaning capacity of the water body. The concept of 'exogenous control + endogenous control + self-purification capacity improvement + comprehensive management' should be followed when treating black and odorous water. The external source control mainly cuts off a pollution source and comprehensively treats point source pollution and non-point source pollution; endogenous control is the removal and solidification of endogenous pollutants (such as river channel dredging and the like); the self-cleaning capacity is improved by communicating water systems, maintaining the water body fluidity, recovering the self-cleaning capacity of a water body ecological system and recovering the river landscape. On the basis, comprehensive management is enhanced, and a perfect monitoring system is established. The treatment of black and odorous water is the foundation, the key is the treatment, and the foundation is ensured.
