Description
Technical field
This application involves integrated domestic sewage treatment devices.
Background technique
In the prior art, the rapid growth of population and industrialized rapid development, so that water environmental problems become more
Carry out more serious global problem.China is as maximum developing country, the quantity and scale in emerging villages and small towns are continuous in the world
Expand, at the same time, since domestic sewage of villages and small towns treatment facility is not perfect, 95% or more resident living sewage and fecal sewage
It is just discharged into natural water without administering, local water source, underground water source and ambient enviroment are caused seriously to pollute, water resources situation is tight
Deteriorate again.In most of rural area water source, the over-standard phenomenon of the indexs various degrees such as ammonia nitrogen, COD, total phosphorus, this just adds
The China Ju Liao originally water environment pollution of very severe, and directly influence the life and health of resident.Currently, raw for villages and small towns
Sewage treatment living is developed, design, Development Techniques process route are reasonable, economical and efficient integration apparatus is by technological innovation
An important development direction for solving the problems, such as domestic sewage of villages and small towns, protection and improvement to villages and small towns water environment have important meaning
Justice.
Processing domestic sewage of villages and small towns most efficient method is the middle-size and small-size sewage disposal device using low cost.Inside equipment
Using biological membrane processing method.Using filler as microorganism carrier, have biomass high, activated sludge loading rate is high, resistance to punching
It is strong to hit load, and can effectively place the advantages that sludge bulking.General technique used is anaerobic and aerobic process, and A (Anaerobic) is
Anaerobism section is used for denitrogenation dephosphorizing；O (Oxic) is aerobic section, the organic matter for going in water removal.Although the technique has system simple
Single, operating cost is low, takes up little area；Save additional carbon expense；Anoxic pond is preceding, since denitrification consumes partial organic substances,
Mitigate aerobic tank load；Aerobic tank can further remove organic matter rear；The basicity that denitrification generates can compensate for nitrifying process pair
The advantages that consumption of basicity, however still inevitably there are some disadvantages in this technique, due to no independent sludge reflux system
System, so that the sludge with unique function cannot be turned out, the degradation rate of hard-degraded substance is lower；To improve nitric efficiency,
Nitrate recirculation ratio must be increased, and denitrification percent is extremely difficult to 90%.
