Description
Technical field
The present invention relates to sewage treatment area, particularly relate to a kind of biological process Sewage treatment systems.
Background technology
Current, water resources is that countries in the world generally face one of urgent problem.According to the research of World Resources Institute of United Nations, World Water money is all faced with than other resource and situation all more severe than ever in quality and quantity.Trillion m3 on the annual industrial water consumption in the whole world according to statistics, and this phenomenon situation is far from it all over the world, demand and limited can be extremely inadaptable by water resources, and the whole world is also hundred billion m3 discharged to the industrial and life contaminated water of natural water every year, cause the Freshwater resources of more than 35% to be polluted, thus pollution control of water will be particularly important.Say that the situation according to Available water resources is determined by the speed of Economic development all over the world in a sense.
The water resources of China also faces serious pollution problem.A large amount of trade effluent not standard discharge, the not treated direct discharge of most sanitary sewage, the agrochemicals such as the unreasonable use chemical fertilizer in vast Rural areas, agricultural chemicals, are on the rise on surface water impact.The Freshwater resources in most of city, the whole nation and area oneself be subject to the destroyed threat of water quality deterioration and aquatic ecosystem.Because the sewage in the whole nation about 80% directly enters waters without any process, cause the section in the whole nation more than 1/3 to be polluted, the urban waters of more than 90% is seriously polluted, and the key cities waterhead area of nearly 50% does not meet drinking water standard.China's city water resource quality is also poor, and most of city and regional ground water table decline continuously, define the Trend of Groundwater Descent Funnel of different scales, and situation is quite severe.Though the basic reason causing water resources to be subject to severe contamination is that a large amount of productive life waste water is unprocessed or treated but below standard.These waste water that must not make full use of and contaminate environment, waste resource again, in the urgent need to carrying out recycling.In various pollutents in water, organic pollutant, the especially organic pollutant of high density, not only in water, lifetime is long, migration circle is wide, and harm is large, intractability is large, is an important subject of field of Environment Protection always.
Summary of the invention
For in the various pollutents in water in above-mentioned prior art, organic pollutant, especially the organic pollutant of high density, not only in water, lifetime is long, migration circle is wide, and harm is large, intractability is large, be the problem of an important subject of field of Environment Protection always, the invention provides a kind of biological process Sewage treatment systems.
For the problems referred to above, a kind of biological process Sewage treatment systems provided by the invention is achieved the goal by following technical essential: a kind of biological process Sewage treatment systems, comprise reaction tank, bio-reactor is provided with in described reaction tank, described bio-reactor comprises at least one group of biological respinse group, described biological respinse group comprises two pieces of microbial films be parallel to each other, between described microbial film, there is closed gas channel, the inlet end of described gas channel and exit end are connected to inlet pipe and escape pipe, and described microbial film is silicone rubber membrane or hydrophobic polymer membrane.
In the present invention, by passing into air or oxygen by inlet pipe and escape pipe between the microbial film be parallel to each other, like this, biomembranous both sides are respectively oxygen side and reaction side, this situation can from the duration of contact of oxygen and film and contact area two aspects, being convenient to oxygen is passed in membranous system, is beneficial to and improves oxygen transfer efficiency to improve sewage treatment capacity; Meanwhile, due to compared to traditional bubble aeration structure, due to oxygen and biofilm contact area certain, the present invention also has the advantage being convenient to control sewage treatment process parameter.
Further technical scheme is:
For making the sewage entering into reaction tank effectively to contact with bio-reactor, also comprise and be arranged on water inlet pipe on reaction tank sidewall and rising pipe, described water inlet pipe is positioned at the below of bio-reactor, and described rising pipe is positioned at the top of bio-reactor.
Can flow uniformly in reaction tank for realizing sewage, being beneficial to organic clearance, all more than one of described water inlet pipe and rising pipe.
For ease of the discharge of mud in reaction tank, the bottom of described reaction tank is also provided with and drains mouth.
For improving the sewage treatment capacity of this reaction tank, described biological respinse group is many groups, and biological respinse group is stacked distribution on the depth direction of reaction tank, and often the spacing organized between biological respinse group is not more than 15cm.
The present invention has following beneficial effect:
By passing into air or oxygen by inlet pipe and escape pipe between the microbial film be parallel to each other, like this, biomembranous both sides are respectively oxygen side and reaction side, this situation can from the duration of contact of oxygen and film and contact area two aspects, being convenient to oxygen is passed in membranous system, is beneficial to and improves oxygen transfer efficiency to improve sewage treatment capacity; Meanwhile, due to compared to traditional bubble aeration structure, due to oxygen and biofilm contact area certain, the present invention also has the advantage being convenient to control sewage treatment process parameter.
