Description
Technical field
The invention belongs to field of environment engineering, more particularly, relate to device and the control method of a kind of large-scale planting industry farmland control runoff pollution, adopt A
2The O oxidation Ditch Technology focuses on agricultural run-off.
Background technology
In recent years, along with the fast development of Chinese society economy, body eutrophication trend is day by day serious.Cause the source of pollution of eutrophication can be divided into point-source pollution and pollution of area source, along with the increasing of point-source pollution management, the control of pollution of area source becomes the key of cutting down the external source pollution load gradually, and rural activity to the contribution rate of pollution of area source up to 75%.The pollutent that agricultural run-off carries is the important component part of farming region pollution of area source, and simultaneously, this is also the important factor that causes the body eutrophications such as lake, river and ocean.Therefore control the pollution of agricultural run-off, for the reduction of prevention and cure of pollution and the outrophication risk [Yang Linzhang that has great importance, Zhou Xiaoping, Wang Jianguo, Deng. be used for ecological intercepting type sewerage and the effect thereof of controlling farmland non-point pollution. ecological magazine, 2005,24 (11): 1371-1374].
A
2O(anaerobic-anoxic-oxic method) be a kind of sewage treatment process commonly used, can be used for B-grade sewage processes or three grades of sewage disposals and middle water reuse, has good Nitrogen/Phosphorus Removal [Gao Tingyao, Gu Guowei, Zhou Qi, Water Pollution Control Engineering (the 3rd edition), Higher Education Publishing House, Beijing, 2007].But A
2O technique has its intrinsic shortcoming, wherein topmost problem be under anaerobic environment denitrification with release phosphorus to the competition of carbon source.
The characteristics of the oxidation ditch process continuous circulation that is sewage in the spaces such as circular or annular has long, the advantage such as sludge loading is low, shock resistance is strong of the residence time.But the denitrogenation dephosphorizing function of oxidation ditch self a little less than, therefore in order to strengthen the processing to nitrogen phosphorus, often increase anaerobism section (pond) and anoxic section (pond) at oxidation ditch water inlet leading portion, but this has just increased cost, has simultaneously the too large shortcoming of floor space.
The technology commonly used of agricultural run-off processing at present comprises: artificial swamp, oxidation pond, biological filter and soil filtration technology etc.For example the open a name of China Patent Publication No. CN 101723560A is called the patent document of processing dispersed wastewater integrated A/O bacteria filter device, this invention relates to a kind of processing dispersed wastewater integrated A/O bacteria filter device, the device profile is cylinder-like structure, the device center is provided with columnar vertical-flow preliminary sedimentation tank, between inside and outside cylindrical shell, partition wall is set, will be divided into equalizing tank, anoxic biological filter, aerobic biofilter, clean water basin, storage basin on the space.Anoxic biological filter, aerobic biofilter and clean water basin are concentric(al) circles arc structure.Sewage in equalizing tank is lifted into preliminary sedimentation tank through airlift, and after precipitation, sewage is distributed into anoxic biological filter denitrogenation together with the backflow nitrification liquid, and the bottom of anoxic pond and middle portion are provided with the back flushing pipeline, can realize the segmentation back flushing; Anoxic pond is communicated with bottom aerobic biofilter, and after denitrogenation, sewage enters the clean water basin water outlet from surperficial overflow after aerobic biofilter is removed organism, nitration treatment.Yet this technique is often due to low carbon source and reason can't complete to Farmland Flow Pollution effective removal such as hydraulic detention time is short, the raising of removing simultaneously standard along with N, P, and single Ecological Disposal technology is difficult to efficient degradation and gets rid of nitrogen phosphorus in water.
