Problems solved by technology

Among them, the subsurface flow constructed wetland has the advantages of various forms, high purification efficiency, and good sanitary conditions, but has the disadvantages of complex structure, high requirements for the concentration of suspended solids in the influent, easy to block, relatively complicated operation and management, high cost and high maintenance cost; table Flow constructed wetlands have low requirements on the concentration of influent suspended solids, are not easy to clog, are easy to manage, and have low cost, but the purification effect of pollutants is relatively low
[0004] Existing ecological purification technologies have certain limitations, which to a certain extent limit the application of ecological purification technologies in raw water from polluted drinking water sources

Embodiment Construction

[0057] The present invention will be further described below in conjunction with specific examples. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the protection scope of the present invention.

[0058]In the present invention, the submerged plants refer to large aquatic plants whose plants are all located below the water layer and live sessilely. Their roots are sometimes underdeveloped or degenerated, and all parts of the plant can absorb water and nutrients. Such as bitter grass (Latin name is Vallisneria spiralis L), hornwort (Latin name is Ceratophyllum demersum), foxtail algae (Latin name is Myriophyllum spicatum L.), hydrilla (Latin name is Hydrilla verticillata (L.f.) Royle ), Najas minor L in Latin, Potamogeton crispus in Latin, Potamogetonaceae in Latin, etc.

[0059] In the present invention, the floating-leaf plant refers to an aquatic plant whose roots are rooted in the bottom soil and w...

Abstract

The invention relates to an ecological purification process for raw water from a polluted source of drinking water. The raw water from the polluted source of drinking water passes through a pretreatment purification unit, a combined wetland purification unit, an efficient oxidation purification unit, a sunken plant purification unit and advanced purification unit in sequence to be treated. The ecological purification process can operate in a modularized manner, has the characteristics of short forming time, good purification effect and wide application range, can be used for treating the raw material from the polluted source of drinking water, and changes the ecological environment of the area of the drinking water source within short time.

Description

technical field [0001] The invention belongs to the technical field of ecological environment engineering, and in particular relates to an ecological purification process of polluted drinking water source raw water. Background technique [0002] At present, in the field of raw water purification of polluted drinking water sources, the widely used ecological purification technologies mainly include artificial wetlands, ecological grass artificial media, ecological floating beds, floating islands, etc. Among them, ecological grass artificial media, ecological floating beds and floating islands are mainly used For the purification of raw water from polluted drinking water sources on a small and medium scale, the artificial wetland purification technology can be applied to large, medium and small ecological purification projects of various scales. [0003] The widely used ecological wetland purification technologies mainly include subsurface flow constructed wetland technology a...
