Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] see Figures 1 to 3 , the present invention provides a technical solution:

[0030] Before designing the ecological restoration system, it is necessary to have a detailed understanding of the water quality of reclaimed water and the water quality of rivers and lakes, compare the water quality indicators, and pay special attention to organic matter, nitrogen, phosphorus and other nutrients that have a great impact on the microbial communities of rivers a...

Abstract

The invention relates to the technical field of sewage treatment and ecological engineering restoration, in particular to a biological restoration system for river and lake ecology by using recycled water from a sewage treatment plant. The biological restoration system includes a stepped bottom foundation, the stepped bottom foundation includes a first step bottom and a second step bottom and a third step bottom, the second step bottom is located between the first step bottom and the third step bottom, and the heights of the first step bottom, the second step bottom and the third step bottom are sequentially decreased. Under the adjustment that planktonic algae and nutrients can be eliminated without use of chemicals, the contents of the nutrients and the planktonic algae in the recycled water are eliminated and solidified in a biological type by arranging a water purification zone, a buffer adjustment zone, a trophic ion solidification zone and a three-dimensional ecological restoration zone, and rivers and lakes are ecologically replenished.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and ecological engineering restoration, in particular to a bioremediation system for river and lake ecology using regenerated water from a sewage treatment plant. Background technique [0002] The quality of reclaimed water is between sewage and tap water. It is non-drinking water that can be used within a certain range after urban sewage and waste water have been purified to meet national standards. It is called the second water source for cities. In the face of the basic national conditions of a large population and a shortage of water resources in our country, urban sewage recycling is one of the effective ways to improve the comprehensive utilization rate of water resources and reduce water pollution. Alleviating the contradiction of water shortage is an important measure to implement sustainable development. Moreover, compared with other water resource development such as seawater d...
