Description of drawings
Fig. 1 is a domestic sewage of villages and small towns diafiltration combined treatment device structural representation of the present invention, shown in Fig. 1 a is operation conditions under normal circumstances wherein, is operation conditions during ice period in the winter time shown in Fig. 1 b.
Embodiment
The present invention is conceived to that treatment effect is good, energy consumption is low, investment and working cost is low, easy to operate, it is simple to safeguard, is applicable to samll cities and towns, residential quarters, tourist attractions and vast Rural areas, and a kind of efficient diafiltration combined treatment device is provided.
Efficient diafiltration combined treatment device of the present invention; By equalizing tank 10, ooze pond 11, aerated reaction pond 12, braiding channel 13 and outlet sump 14 soon and form; The bottom of wherein oozing pond 11 soon is aerated reaction pond 12; Ooze soon between pond 11 and the aerated reaction pond 12 and be provided with braiding channel 13, and connect outlet sumies 14 through this braiding channel 13, the water after the processing is discharged through the water port 141 of outlet sump 14.
One side of oozing pond 11 and aerated reaction pond 12 soon is connected with equalizing tank 10, and is provided with first intake sluice 111 between pond 11 and the equalizing tank 10 oozing soon, and between aerated reaction pond 12 and equalizing tank 10, is provided with second intake sluice 121.Equalizing tank 10 is provided with a water-in 101, and pending sewage is got in the equalizing tank 10 by water-in 101, and this equalizing tank 10 plays the effect of mixing well water quality and quantity, and regulates the water distribution of whole device.
Ooze pond 11 soon and remove structure for strengthening nitrogen, in oozing pond 11 soon, be filled with the filtrate 112 of human configuration, this filtrate 112 is to be mixed by arbitrary proportion by Dali stone sand, fine sand, zeolite sand.Be covered with the thick planting soil of 300mm on the top of filtrate 112, well developed root system, the tall and big plants 113 of plant such as the earth layer plantation reed of this planting soil, cattail can be promoted the oxygen transmission quantity that oozes pond 11 soon.Being filled with diameter in the aerated reaction pond 12 is the gravel 122 of 16-32mm, and 12 bottoms, aerated reaction pond are positioned at filler below and disc type aeration head 123 is installed carries out oxygenic aeration.Being filled with diameter in the braiding channel 13 is the gravel 131 of 32-64mm.
Device of the present invention can be in normal condition (oozing the pond does not soon have freezing) operation, also oozes top, the pond luck row that freezes in the winter time the time soon.Below respectively the operation of above-mentioned two kinds of situations being done one specifies.
Embodiment 1
See also Fig. 1 a, represent that device of the present invention is to move in standard state.
Be provided with the twice intake sluice in the equalizing tank 10 of the present invention, pond 11 water inlets are oozed in 111 controls of first intake sluice soon, 121 control aerated reaction pond 12 water inlets of second intake sluice.During normal the operation, second intake sluice 121 is closed, and first intake sluice 111 is opened, and the sewage in the equalizing tank 10 get into and ooze pond 11 soon, and the performance and the consumption that ooze filtrate 112 in the pond 11 soon are the key factor that influences wastewater purifying efficiency.For improving the hydraulic load of system; To water quality of river pollutent and the lower characteristics of organic concentration; Of the present invention oozing soon selects Dali stone sand, fine sand, zeolite sand as filtrate in the pond, this filtrate absorption property is good, and a large amount of specific surface areas can be provided for the apposition growth of mikrobe; Enough porositys are arranged, and good permeability can guarantee the supply of oxygen; Better chemical stability is arranged; Microbial growth is had no adverse effect; Raw material is extensive, and is cheap and easy to get.
Oozing 11 bottoms, pond soon is braiding channel 13, and being filled with diameter in the braiding channel 13 is the gravel 131 of 32-64mm.Braiding channel 13 links to each other with outlet sump 14, and the water after the processing is discharged through the water shoot 141 of outlet sump 14.
Embodiment 2
See also Fig. 1 b, represent that device of the present invention is to move in ice period.
Device of the present invention moves in the north, and top (more than the frost line) A that oozes the pond during ice period soon can freeze, and winter, reed root system reoxygenation ability was relatively poor, for keeping the normal operation of system, need carry out a spot of gas distribution, when satisfying nitrification function to the demand of oxygen-supplying amount.
Device of the present invention is when moving ice period; First intake sluice 111 in the equalizing tank 10 is closed; Second intake sluice 121 is opened, and sewage gets into aerated reaction pond 12, and being filled with diameter in the aerated reaction pond 12 is the gravel 122 of 16-32mm; The bottom in aerated reaction pond 12 is provided with a plurality of disc type aeration heads 123, connects oxygen hose 124 oxygenation in aerated reaction pond 12 of peripheral hardware.The water outlet in aerated reaction pond 12 gets into oozes pond 11 frost lines soon with lower area, further purifies water.Oozing formation oxygen-starved area B between 11 bottoms, pond and the braiding channel 13 soon, is that carbon source is carried out denitrification function with the organism in the sewage.
Because the admixture of whole device is preferable, can be used as the electron donor of oxygen-starved area through the low-carbon (LC) organism that generates behind the aerobe membrane degradation, and the nitrated acidity of bringing can be neutralized very soon also, be beneficial to the carrying out of anti-nitration reaction.Aerobic biologic membrane helps the best effect of different flora performances with the oxygen-starved area in different spatial distributions.Whole plant area area is little, is convenient to operational administrative, can cross to reach the function of removing organism and denitrogenation.The water outlet of oxygen-starved area B gets into braiding channel 13, discharges through the water shoot 141 of outlet sump 14.
The hydraulic load of device of the present invention is generally 1.5m/d (m
3/ m
2.d), handle every side's sewage floor space and be about 0.4m
2/ m
3.d.System of the present invention does not receive place restriction applied range and construction investment is few, overhead charges are low, hydraulic load is high, easy to operate, be easy to management.The present invention is applicable to samll cities and towns, residential quarters, tourist attractions and vast Rural areas; Also can normally move winter; Be applicable to the processing of contaminated rivers and canals water, municipal effluent and sewage; Water quality of processed water can reach " municipal sewage plant's pollutant emission standard " one-level A standard (GB18918-2002) or " miscellaneous domestic water quality standard " (CJ25.1-89), but reuse.
