Description
Technical field
The utility model relates to environment-protective water process field, is specifically related to a kind of sedimentation basin.
Background technology
China is about 6.74 hundred million people in the countryside at present, and more than 250 ten thousand natural villages, every day, more than 3,000 ten thousand tons of quantity of wastewater effluent, accounted for national Sewage Water Emissions amount more than 50%.From 2006 to 2013, National urban wastewater treatment rate rose to 99.1% from 55.7%, at present close to saturation state; County town wastewater treatment rate rises to 82.6% from 13.6%, and wastewater treatment rate obviously promotes.And village wastewater treatment rate is only 7.0% at present, only the rural domestic sewage treatment ratio of minority developed provinces and cities as Beijing, Tianjin, Shanghai, Jiangsu, Zhejiang, Guangdong etc. can reach about 10%; Shanghai reaches 43%, for the whole nation is the highest; Other most of provinces are also not fully under way, just carried out pilot in part villages and small towns.
" water prevention and cure of pollution action plan " (" ten, water ") is put into effect.According to measuring and calculating, the investment demand that " ten, water " measures is implemented completely will reach 2 trillion yuan.Investment will relate to newly-built sewage treatment facility, mark transformation, pipeline network construction and villages and small towns sewage disposal four bulk are put forward by existing sewage treatment plant, and this is also the major fields of Present Domestic sewage disposal.Villages and small towns market of sewage treatment will welcome " large opportunity+challenge greatly ".Predict that China's country sewage discharge capacity in 2015 is about 14,800,000,000 tons.Suppose to reach 20% calculating with handling rate, then rural sewage treatment potential market scale in 2015 can reach 40,800,000,000 yuan (do not comprise facility build up after operation market scale).Villages and small towns market of sewage treatment has a high potential.
Conventional active sludge treatment process shortcoming: floor space is large, operation is complicated, invests high, and energy consumption is large, and sludge yield is higher, and effluent quality is poor, and nitrogen, tp removal rate are low.
The technique capital costs such as artificial swamp, stabilization pond, land treatment system are low, run in energy consumption low, management is simple, while protection of the environment, improve regional area view, be adapted to new countryside construction.But there is effluent quality instability, treatment effect large, the shortcoming such as dwell time of sewage is long and floor space is large affected by environment, be only applicable to weather suitable, there is a large amount of low-lying lands and the rural area of vacant land.
According to the feature of villages and small towns sewage and country to the requirement of new village of promoting a conservation culture, the technique of suitable China villages and small towns sewage disposal should possess stronger anti impulsion load ability, and removal efficiency is high; Simple process is flexible, stable, maintenance management convenient; Capital expenditure is economized, operating cost is low, save energy and reduce the cost obviously; Present stage process emission request up to standard can be adapted to preferably and consider to carry out the features such as the change of regeneration needs with following.For the treatment process of country sewage dispersion treatment project recommendation in " rural domestic sewage treatment project construction and guide to investment " that national environmental protection portion issues in November, 2013: small-scale artificial wetland, land treatment systems, stabilization pond, purifying biogas generating pit, integrated sewage treating apparatus.
The main Problems existing of wastewater treatment in China has: pipe network is supporting to relatively lag behind, heavy water light mud phenomenon is general, upgrading is very urgent, reuse of wastewater degree is low, the management of the construction operation of sewage treatment plant still needs to strengthen and sewage treatment works is not also carried out on a large scale.
Along with China's population increases sharply, water requirement sharply increases progressively.Developing to middle-size and small-size distributing from centralized on a large scale for adapting to China's national situation sewage disposal scale, forming the situation of " based on large-scale, middle-size and small-size complementation ".The application and development of these integrated water treatment facilities provides new opportunity.
