Description
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of modular structure and application art thereof of small-sized artificial swamp.
Background technology
" Chinese countryside safe drinking water supervision of construction practice and exploration " report according to Ministry of Water Resources's issue in 2010; More than 60 ten thousand administrative villages, the whole nation, more than 250 ten thousand natural villages; Peasant household more than 200,000,000, nearly 800,000,000 people are living; The dangerous population of rural potable water is about about 3.23 hundred million people, and wherein 9,084 ten thousand people receive the influence that water pollutes.
Causing the reason of this problem is that the rural area does not have sewage treatment facility.In the sample survey of national domestic sewage of villages and small towns in 2009, through more than 200 administrative village of investigation, the village that has sewage treatment facility only accounts for 2.6%.The main contribution of villages and small towns, basin sewage in pollution load surpasses 50%, become the important factor that the main basin water of China pollutes.
Firmly the portion of building representes, the emphasis of " 12 " energy-saving and emission-reduction is just in the Pollution abatement in rural area.According to country's " 12 " national villages and small towns waste water control planning, reinstated about 30 years from 2010, set up the facility and the service system of perfect draining and WWT in the villages and small towns of China 90%.To the year two thousand twenty, make 30% villages and small towns population obtain fairly perfect public draining service, and each villages and small towns sewage pollution problem of laying special stress on protecting in the district of China is controlled comprehensively and effectively.During " 12 ", national villages and small towns waste water control rate will promote 10%.Domestic sewage in rural areas by using is administered in flakes and will be got into the key stage.
The difficult point of rural area water pollution control mainly contains three aspects: at first, domestic sewage in rural areas by using have have a large capacity and a wide range, organic concentration is higher, and characteristics such as daily variation factor is big, intermittently discharged, control difficulty.Secondly, lacking of capital is that the peasant administers the big Root of Clark Clematis that water pollutes.Rural environment protection belongs to that the responsible party is difficult to differentiate or the responsible party too many, public welfare is very strong, the less field of rate of return on investment, and social funds are lacked magnetism.Agglomeration, rural area and samll cities and towns are because the monomer market scale is little; Its infrastructure construction and operation are difficult to carry out market operation; Thereby must rely on financial fund; And small towns and the general financial resources of village level administrative organization are not enough, are difficult to build Pollution abatement Infrastructure, and this has just caused the pollution of agglomeration, rural area to be on the rise and will continue serious situation.At last, the rural environment level of management are low, the rules imperfection, also are the serious day by day major reasons of rural area pollution problem.
The Chinese city waste water control has very rich experience, and country sewage was just administered since 2000.No matter be government or unit in charge of construction, got used to doing city improvement, just be used in the set of rule cover in city on the rural area, always go wrong." suiting measures to local conditions " is the core principles of Chinese countryside waste water control, can not consider rural problem according to the thinking in city, must pay close attention to the characteristics and the actual state in rural area.
