Description

The one underground sewage disposal system of a kind of samll cities and towns and country sewage and reuse technology
Technical field
The invention belongs to water, waste water, sewage treatment area, particularly to one underground sewage disposal system and the reuse technology of a kind of samll cities and towns and country sewage。
Background technology
Along with the development of urbanization, China's rural population quantity is downward trend year by year。By the end of the year 2012, China's rural population quantity 6.4 hundred million, rural population accounts for the 47.4% of country's total population。
Chinese Ministry of Environmental Protection's " Chinese environmental situation bulletin " shows, starts to increase the discharge statistics of agricultural sources Wastewater Pollutant from 2011。From the statistical data of 2011-2013, China's agricultural sources Wastewater Pollutant discharge capacity maintains a high position。By the end of the year 2013, China's COD total emission volumn 2352.7 ten thousand tons, wherein agricultural sources COD 1125.7 ten thousand tons (889.8 ten thousand tons even above life source), account for the 47.8% of total emission volumn；Ammonia nitrogen total emission volumn 245.7 ten thousand tons, wherein agricultural sources ammonia nitrogen 77.9 ten thousand tons, account for the 31.7% of total emission volumn。
From 2006 to 2013, whole nation the planned city wastewater treatment rate rose to 99.1% from 55.7%, at present close to saturation；County town wastewater treatment rate rises to 82.6% from 13.6%, and wastewater treatment rate is also obviously improved。
And rural sewage treatment rate is far below the planned city and county town。2012, village wastewater treatment rate was only 7.0%, and only the rural sewage treatment cause of minority developed provinces and cities obtains certain achievement。Village's ratio that domestic sewage in rural areas is processed by the minority developed provinces and cities such as Beijing, Tianjin, Shanghai, Jiangsu, Zhejiang, Guangdong can reach about 10%；Shanghai reaches 43%, the highest for the whole nation；Other major part provinces are also not fully under way, simply carried out pilot in part villages and small towns。
From region zones, east rural sewage treatment rate is the highest, and Midwest rural sewage treatment rate is relatively low。2010, east, middle part, west area were carried out the village of rural domestic sewage treatment and are accounted for the ratio of respective village sum respectively 9.4%, 2.6%, 2.1%, all not up to 10.0%。
According to " rural domestic sewage treatment project construction and guide to investment ", in domestic sewage in rural areas separated practices construction investment standard, small-scale artificial wetland ton water invests 2600-3700 yuan/ton, land treatment systems 2000-3300 yuan/ton, stabilization pond 1900-3300 yuan/ton, small-sized integrated sewage-treatment plant 11000-39000 yuan/ton。
Development along with Re-search on Urbanization, it is assumed that annual rural population is with 2% decrease of speed, and country sewage discharge capacity was approximately 14,800,000,000 tons in 2017。
Rural sewage treatment rate aspect, according to " General Office of the State Council is about printing and distributing 12 whole nation urban wastewater treatment and the notice of regeneration Facilities Construction planning ", by 2015, organic town of China wastewater treatment rate reached 30%。Owing to rural sewage treatment rate is affected by the factor in many ways such as policy, market, technology, it is contemplated that by 2015, rural sewage treatment rate was likely lower than organic town's wastewater treatment rate 30%。Assume that 2014-2017 treatment facility is built unit price and remained unchanged, reach 20% calculating with rural sewage treatment rate, then rural sewage treatment potential market scale in 2017 40800000000 yuan。
Villages and small towns average population in 5000 human world, people ~ 30000, displacement average out to 500 ~ 3000m3/ d, the buried sewage disposal device separate unit disposal ability of General Decentralized formula is less than 500m3/ d, the investment of processed in units amount is higher, and high for requirement for anticorrosion, as easy as rolling off a log causes leakage scenarios, causes farmland and rivers and canals to pollute；All the other land treatment systems methods all need to take a large amount of soil, require higher to addressing, cause land wastage serious。
