Embodiment 1

[0033] A method for purifying multiple sewage in a polder area by using the ditches and ponds ecosystem in the polder area, comprising the following steps:

[0034] The method of this embodiment is implemented in the west of Niujiao Dawei in Yandun Street, Baohe District, Hefei City, the southwest Yipai River embankment, and other directions are all close to agricultural areas and residential areas in the polder. Ditches and ponds are widely distributed in this area, and non-point source pollution, domestic sewage, and initial rainwater in the polder enter from the northwest end of the implementation area through ditches, and flow out from the southeast end after being purified by the ditches and ponds ecosystem. Before the treatment, the method implementation area was in the original ecological state, with weeds overgrown, water peanuts growing wildly in the ditches and ponds, causing some areas to become silted and swamped, the ditches and ponds were blocked, unable to flow, ...

Abstract

The invention belongs to the field of water treatment environmental technologies, and in particular relates to a method for purifying polder area multiple sewage by using a polder area ditch-pond ecological system. According to the process provided by the invention, by virtue of integration and optimization of ecological restoration combination technologies including a polder area ditch-pond form transformation technology, a polder area ditch-pond water system communication technology, a foundation base repair and transformation technology, an aquatic animal and plant restoration technology, an aquatic plant floating bed strengthening technology and the like, a polder area ditch-pond system water purification comprehensive improvement engineering, which takes water quality improvement as a basis and ecological restoration as a core and also gives attention to landscape promotion, is constructed. The method can significantly improve the environmental quality of polder area ditch-pond water to realize organic combination of water purification and landscape promotion, thereby not only effectively reducing wastes of polder area soil and water resources, but also significantly reducing material resource, money resource and manpower inputs on polder area environmental management by government. Moreover, the process provided by the invention aims at purifying the multiple sewage, which is polluted by agricultural surface sources, industrial point sources, town and rural lives and initial rainwater, in polder area ditches and ponds.

Description

technical field [0001] The invention relates to the technical field of water treatment environment, and more specifically relates to a method for purifying multiple sewage in the polder area by using the ditch pond ecosystem in the polder area. Background technique [0002] The polder area is an area where dikes are built to resist floods and engage in agricultural production. Due to the low-lying terrain, there are many ditches and ponds in the polder area, and the water volume is relatively large. However, with the rapid development of industry and agriculture, the improvement of people's living standards and the irrational use of land, a large amount of clean water in ditches and ponds has long been polluted by agricultural non-point sources, industrial point sources, urban and rural life pollution, and initial rainwater pollution. The multiple polluted water caused by the ditches and ponds in the polder area deteriorates the water quality, decreases the diversity of aqu...
