Description
Technical field
The invention belongs to ecology and field of environment protection, relate to underload river water cleaning field, section, farmland, relate in particular to a kind of method of utilizing natural biology membrane reactor to purify underload low temperature river.
Background technology
At present, body eutrophication problem is just having a strong impact on the mankind's living environment.Over nearly 10 years, China's rivers, storehouse, lake eutrophication are very serious and be degradating trend.In more than 700 river of China (overall length 100,000 kms), 70.6% river is polluted.It is dangerous that China rural area has people more than 300,000,000 to drink water, and wherein approximately more than 6,300 ten thousand people drink water of high fluorine content, and 2,000,000 people drink high arsenic water, and more than 3,800 ten thousand people drink brackish water, and 1.9 hundred million people's tap water harmful substance contents exceed standard, and Schistosomiasis Endemic Areas approximately more than 1,100 ten thousand people drink water dangerous; Quite a few urban water resource is seriously polluted, threatens quality of drinking water.
Farmland pollution of area source is one of China's principal mode of entering dystrophication load, and the discharge of farmland pollution of area source has brought the pollutent of a lot of underloads to river course nearby.Due to this pollutant underload, brought a lot of new challenges to conventional treatment process, the cost performance of processing as traditional activated sludge process is not high.
At present, for the treatment process of this class underload river, be divided into two classes, a class is original position purification of water quality method, and another kind of is the bypass method of purification (claiming again dystopy facture).The bypass method of purification is to utilize the vacant lot on both sides, river course, builds river water cleaning system, as wet land treating system, biological pond, soil filtration etc.For example: for what cut down Dian Chi, enter lake pollution load, the thinking purifying based on bypass has designed and built the biological stabilization pond system that comprises Aquatic-plant Pond and culture pond, has investigated the removal effect to nitrogen, phosphorus.Result shows, this system is to TN, TP, NO
3 --N and NH
3the average removal rate of-N is respectively 25.3%, 50.6%, 38.4% and 35.6%, also has certain ecoscape benefit when improving water quality, and the purification that can be other water body provides demonstration.The feature of the bypass method of purification is exactly to build economically viable treatment system in conjunction with river water quality feature, but this class bypass method of purification needs power water lift conventionally, has increased processing costs, also needs to increase manpower and manages and protects.
Therefore, there is research that this bypass purifying method is carried out to upgrading, as construction that bypath system is combined with traditional sewage purification system (as denitrification dephosphorization system).The problems such as patent of invention (application number 201110159014.4) is high for the water inlet sediment concentration often running in current denitrification dephosphorization technique, VSS/MLSS is on the low side, carbon source is not enough propose a kind of bypass mud decrement, silt separation and denitrogenation dephosphorizing Sewage treatment systems and method, main body Sewage treatment systems and the bypath system two portions with denitrogenation dephosphorizing function, consist of.Main body Sewage treatment systems comprises settling pit and has the Sewage treatment systems of denitrogenation dephosphorizing function.Bypath system is comprised of hair separator, mud decrement pond, mud silt separator and silt dewatering system and chemical phosphorus removal system.This way that combines with bypass clean-up system and build, can prevent that silt from accumulating in Sewage treatment systems, promote mud VSS/MISS ratio in biochemical reaction tank, in embedded bypath system, be aided with chemical dephosphorization, can realize the low cost chemistry of sewage phosphorus and remove and reclaim.
