Technical field:
The present invention relates to a kind of ecological engineering combination technique that is applicable to reuse water nutritive salt deep purifying, belong to environmental engineering, ecological engineering, Garden Engineering technical field.
Background technology:
The shortage of water resources problem is prevalent in the most of areas of China, and in many areas of northern China, shortage of water resources becomes the bottleneck problem of Economic development, the aquatic attitude health of water surrounding especially gradually.Be that rainfall amount forms the resource lack of water less by weather and geographical position decision on the one hand; On the other hand, Economic development brings water pollution, and the aquatic attitude of water surrounding continues to worsen, and causes available water source to reduce year by year.Under this situation, the development and use of reuse water come into one's own increasingly, can improve the water body cyclic utilization rate, can realize in the development and use process that again the purification of pollutent is removed.
Since China's " the Seventh Five-Year Plan ", just carried out research, and built up a plurality of regeneration water factory in succession reclaimed wastewater reuse, after sewage disposal, develop water for reclaimed water, industrial colling, afforestation pour water, ecological supplementary feed etc.At the development and use of reuse water, China has also put into effect corresponding water quality standard, has effectively ensured the reuse safety of reuse water.When reclaimed water reuse is ecological supplementary feed, generally carry out with reference to the landscape water reuse standard of China.But standard is on the low side to water quality requirement, far can not reach ground Table V class water quality standard.For the water body with better self-purification capacity, reuse water water quality is on the low side and no problem.But at present, the many water body water yields of northern China are little, flow slowly, and water body self-purification ability and water environment capacity are low, the higher requirement that this just proposes the water quality of reuse water.Reuse water further must be purified, remove nutritive salt such as wherein residual nitrogen, phosphorus, thereby reduce after the reuse water supply influence water body.
Generally research and development form existing many engineerings at sanitary sewage or rain flood, because water quality characteristic is different with reuse water, technology also is not suitable for the deep purifying of reuse water.At first, after reuse water had passed through reuse water factory and office reason, pollutent had purified degraded to lower concentration.Secondly, change has taken place in the occurrence patterns of pollutent, and most of pollutents exist with solubilised state, and particulate form is few.Moreover the concentration ratio of pollutent is different with sanitary sewage etc., and outstanding behaviours is higher at nutrient concentrations such as nitrogen, phosphorus, and organic concentration is less relatively.Because the transformation of above-mentioned water quality characteristic, when traditional environment project and ecological engineering technology were applied to the reuse water deep purifying, the actual motion effect was relatively poor relatively.Therefore, along with Economic development, water resources are utilized the transformation of trend, but the engineering of residual contaminants just has higher actual value and meaning in a kind of significant depth purifying regeneration water that is applicable to reuse water water quality of research and development.
Summary of the invention:
The object of the invention is to research and develop and a kind ofly is adapted to China's reuse water water quality, but the ecological engineering combination technique of residual nitrogen and phosphorous nutrient in the deep purifying reuse water ensures the water quality of reuse water as ecological supplementary feed, and the health of receiving water body.
For achieving the above object, the technical solution used in the present invention is: adopt the artificial pool, artificial swamp, three kinds of ecological engineering technologies of vegetation buffer strip, optimize and techniqueflow optimization through each modular construction, form a whole set of effective integration engineering technology (Fig. 1).
Comprise two rank artificial swamps in A, the integration engineering technology, be drowned flow artificial wet land and the surface low artificial swamp is formed in parallel.The artificial swamp unit is the core unit in the combination technique, and most of pollutent is removed at this purification unit.Wherein drowned flow artificial wet land adopts gravel as matrix, and the surface low artificial swamp adopts original-state soil as matrix.
Comprise two facultative lagoons and an oxidation pond in B, the integration engineering technology.The artificial pool is the important supplementary units of artificial swamp, assists artificial swamp to realize pollutant removal.
C, vegetation buffer strip are positioned at integration engineering technology terminal, in the time of full-scope safeguards reuse water effluent quality, are connected artificial ecosystem and natural ecosystems.
Integration engineering technical system of the present invention mainly contains following characteristics: 1) parallel-connection structure of drowned flow artificial wet land and surface low artificial swamp helps realizing the mutual supplement with each other's advantages of the two, current wetland has ensured the pollutant purification ability of system, and surface-flow can prevent that then cross flow from appearring in current wetland; 2) gravel through lab scale, pilot scale and engineering verification, has good pollutant purification effect for reuse water water quality as drowned flow artificial wet land matrix; 3) in conjunction with reuse water water quality and as the application characteristic of ecological supplementary feed, both degradation of contaminant had the ecological recovery effect again to techniqueflow closely.
