Description
Technical field
This utility model belongs to technical field of sewage treatment equipment, particularly to a kind of integration combined biological filter tank.
Background technology
China always payes attention to Water Pollution, in recent years, achieves the biggest effect, and quality of water environment has changed
Kind, but existing problems are still severe.Being mainly manifested in, concentrated contaminated water source, city is paid attention to and is administered, and concentrates and build in city
Becoming district's water environment to obtain a certain degree of improvement, it is dirty that the main pollution to water body at present is changed into early-stage rainwater by point-source pollution
Dye, widespread pollution from the overuse of fertilizers and pesticides in rural area and the pollution of rural scattered domestic sewage.
Rural Water Pollution thing discharge capacity maintains a high position, accounts for more than the 50% of whole nation Sewage Water Emissions amount, and due to rural area
Sanitary sewage is away from urban pipe network, and collection sewage conduct cost performance is low, is affected by fund, and handling rate is on the low side, currently mainly adopts
Process by decentralized type sewage processing means.
At present, scattered domestic sewage treatment device major part uses Wastewater Treated by Activated Sludge Process device, also has part biological
Embrane method processing means, on the whole, operational effect is bad.In addition to the management reason such as not in place, the choice of technology there is also and ask
Topic.
The difficult point of a part of rural sewage treatment maximum is that sewage quantity is unstable, and on the one hand reason is, is divided by rural residence
The factor impacts such as scattered, hypsography, it is lower that sewage collection system builds sexual valence, and sewage is difficult to all collect；On the other hand
Reason is, is affected by rural population Out-migrant for work etc., and population fluctuation's property is big, and festivals or holidays, population was more, and permanent resident population is few at ordinary times, place
Reason device to adapt to different water yield requirements, requires higher to its anti-undulatory property.
Rural area uses activated sludge method processing technique (such as A/O method, A/A/O method, biological contact oxidation process, MBR mostly at present
Method etc.), owing to sewage quantity is unstable, design load is on the low side at ordinary times, it is difficult to form sufficient concentrations of biological sludge, treatment effect without
Method ensures, after partial devices comes into operation, is in idle state.
There is provided and a kind of adapt to country sewage water quality, the sewage-treatment plant of feature that water yield undulatory property is bigger has very much must
Want.
