Description

A kind of comprehensive ecological management system of the domatic at the bottom of pond eutrophication water of hard

Technical field

This utility model is related to the technical field of water body in lake restoration of the ecosystem and in particular to a kind of hard domatic at the bottom of pond richness is sought The comprehensive ecological management system of fosterization water body.

Background technology

Eutrophication is the subject matter that current Water Environment In Lakes face, and for a long time, people constantly explore eutrophication The approach of water body treating.Eutrophication is the impact due to mankind's activity, the nitrogen needed for biology, the enrichment of phosphorus nutrition material, draws Play algae and other plankton breeds rapidly, Dissolved Oxygen in Water amount declines, Fish and the mortality of other biology, water quality deterioration Phenomenon.Eutrophication be water body in lake growth, develop, aging, wither away whole life cycle in must through natural process, its process Very long it is often necessary to its process is described with geological epoch or century.And because anthropogenic discharge contain nutrient substance industrial wastewater and Body eutrophication phenomenon caused by sanitary sewage, the speed that it develops is very fast, can make water body in a short time by lean nutrition State is changed into eutrophic state.Eutrophication and is mainly shown as plankton amount reproduction in water body, occurs " wawter bloom " Phenomenon.It is mainly the impact that human activity produces for now.

At present, nation-building process high speed development, people required to improve constantly therewith to quality of life, many urban construction Introduce the man-made lake projects such as water body is built, lake is built, part man-made lake is domatic and at the bottom of pond hardening water body, side slope is steeper（Slope Than steep in 1:3）, no ecosystem, cause newly-built man-made lake body eutrophication to be on the rise, water body degradating trend substantially, people The news present situation in work lake fouling pool has been encountered with many times, and water ecology is repaired extremely urgent.

Traditional purifying eutrophication water body mode is water diversion and renewal, adds chemistry or microbial reagent, set using oxygenation Apply or equipment carries out to water body forcing oxygenation etc..Wherein, water diversion and renewal measure needs abundance, convenient cleaning water source as changing Water water source, simultaneously this kind of mode have that water stabilization degree is poor, pollution transportation the shortcomings of；Add chemistry or microbial reagent exists Fund input is big, water quality easily repeatedly, have secondary pollution problems；There is energy consumption greatly in forced aeration measure, processing cost is high to be waited not Foot.

Ecological Measures predominantly carry out water process using the mode of ecosystem, that is, simulate the Producer in nature, disappear Fei Zhe, decomposer, meticulous reasonable disposition, so that whole food chain is more and more abundanter, make ecosystem more and more stable, use Self purification function of nature itself is reaching the purpose purifying water.

Restoration of the ecosystem is for ecological disruption, the ecosystem structure function of ecological disruption and relation broken Bad, hard domatic at the bottom of pond water body does not possess and carries out restoration of the ecosystem by Ecological Measures, belongs to ecological disruption, and restoration of the ecosystem is exactly The relation of the rational structure of restored ecosystem, efficient function and coordination, is function and the phase rebuilding damaged ecosystem Physics, chemistry and the biological nature closed.Its essence is the necessary function of recovery system and makes system reach the state of self-sustaining. The purpose repaired is intended to reproduce one naturally, and the ecosystem of energy self regulation is so as to form one with the ecoscape being located Individual complete entity.

Additionally, natural lake is compared, the man-made lake of hard domatic at the bottom of pond eutrophication water type due to the needs of function, There are structures all to be built by the way of through engineering approaches, how to improve lake view, reduce manual vestige as far as possible, with With surrounding landscape phase coordinate, be also lake build it is also contemplated that problem.
