Water sieve plate is divided, along constituting, several water holes to be uniformly distributed on the sieve plate, water hole plays by sieve plate and the sieve plate of its surrounding
Water is allowed to flow uniformly through the effect of sieve plate.
The working principle of the utility model is as follows:
1, sewage enters by-pass filtration pond by the main water inlet tube below by-pass filtration pond when system works, later sewage
Nitrification filler uniformly and is slowly flowed through, the impurity such as excrement in water can be stuck on nitrification filler, be grown by nitrification filler surface
Microorganism decomposed, while the nitrobacteria that molten ammonia nitrogen in water can be grown by nitrification filler surface is converted to nitrous acid
Salt is further converted to nitrate, nitrifying process net reaction at this time are as follows: NH4++1.83O2+1.98HCO3 -→
0.021C5H7O2N+0.98NO3 -+1.04H2O+1.884H2CO3
The constantly upper length of water level in by-pass filtration pond, reaches position shown in water level line a, at this moment most of water can be from spilling water
Pipe a overflows into the dividing on water sieve plate a of secondary filtration pond.
2, the denitrification filtering of denitrification filtering bottom of pond portion is connected to due to being embedded with inside the nitrification filler in by-pass filtration pond
Pond water inlet pipe, and the position of overflow pipe b is lower than the position of overflow pipe a, therefore the water level in denitrification filtering ponds is lower than level-one
Pool water level is filtered, causes have a small amount of water that can ceaselessly flow through denitrification pond automatically, is flowed into secondary filtration pond from overflow pipe b
Divide on water sieve plate a.This part water is flowed into from the bottom of pond pipe of denitrification filtering bottom of pond portion, then slowly flows through denitrification filler, this
When denitrification filler surface on the denitrifying bacteria that grows the molten nitrate by water is resolved into nitrogen, carbon dioxide and water,
Denitrification process net reaction is (by taking methanol is carbon source as an example):
NO3 -+1.08CH3OH+0.24H2CO3→0.056C5H7O2N+0.47N2↑+1.68H2O+HCO3 -
Since its content can may not be reduced to by the breeding water containing nitrate when once flowing through denitrification filler
Ideal concentration, therefore water circulating pump is set, the water for having flowed through denitrification filler is drawn onto denitrification filler by water circulating pump again
Below, it so that water be allow to flow through denitrification filler back and forth, allows denitrification filtering to carry out with this more thorough, gives full play to
The denitrification function of equipment.Since denitrifying bacteria needs just can normally reduce nitrate under anaerobic, following
It is provided with a point water sieve plate b above the water inlet of ring water inlet pipe, has been connect with air with preventing water circulating pump to be drawn above apertured partition
Touching and dissolved with the water of oxygen, it is ensured that denitrification filtering ponds are in an oxygen-free environment, and anti-nitration reaction can be gone on smoothly.
The switch size of flow control valve is adjusted by measuring nitrate content in the water that flows out of overflow pipe b, thus
Determine flow through denitrification filler water how much.Flow control valve is turned down if nitrate content is excessively high, water is increased with this
In reaction time between the denitrifying bacteria of denitrification filler surface growth, further decrease nitrate content；If nitric acid
Salt content is too low, opens big flow control valve, is reduced with this anti-between water and the denitrifying bacteria of denitrification filler surface growth
Between seasonable, the water of anti-nitration reaction processing is increased.The size specifically adjusted need to be when breeding production be normally carried out, by not
The nitrate content of water obtains optimum valve regulation scheme at disconnected tracking overflow pipe b.
Chemical reagent needed for anti-nitration reaction (by taking methanol as an example) is added in denitrification filtering ponds by chemical feed pipe, circulation
Water pump is mixed into methanol uniformly in the water in pond.Check valve prevents the aqueous reflux in denitrification pond to chemical feed pipe.
3, the water for flowing through by-pass filtration pond and flowing through denitrification filtering ponds eventually flows to be located at dividing at the top of secondary filtration pond
On water sieve plate a, water sieve plate a is divided to make the uniform sprinkle of water on inclined tube filler, finally collect in secondary filtration pond bottom of pond, gone out from master
Water pipe flows out this system.In the process, water constantly collides with inclined tube filler when flowing through hanging inclined tube filler, most
The big possible surface area for increasing water, the nitrobacteria grown on inclined tube filler further divide the harmful substance in water
Solution.
