Description
Technical field
The present invention relates to a kind of unpowered bio-filter water purifying system that has oxygenation and backwashing function concurrently, belong to water-treatment technology field, in can be used for, the purifying treatment of oligosaprobic landscape water, Sewage Plant tail water, life and rural sewage.
Background technology
Under the background of, Global climate change seriously polluted in power supply anxiety, water, it is particularly important to advocate energy-saving and emission-reduction in the whole society.All kinds of process for purifying water and equipment emerge in an endless stream aspect water treatment, and wherein common have filtering system and biological filter reactor or the like.But there is power consumption mostly in common filtering system, easily shortcomings such as obstruction and pipe valve complex structure takes place, and monomer filter plant itself does not possess biochemical reaction functions such as oxygenation, nitrification and denitrification yet.And problems such as the also ubiquity power oxygenation power consumption of submerged biological filter, easy generation obstruction and purifying water effect difference.Above-mentioned defective all influence and limited the biofiltration process for purifying water produce and life in widespread use.
Summary of the invention
Problem at above-mentioned technological method and equipment existence, the invention provides a kind of unpowered bio-filter water purifying system that has oxygenation and backwashing function concurrently, this water cleaning systems need not that power just can carry out anaerobism, hold concurrently oxygen and biochemical reaction such as aerobic, remarkable to the solid phosphorus effect of sewage water denitrification, and can carry out power-free back washing, keep not blockage phenomenon of biological filter long-time running.
To achieve these goals, a kind of unpowered bio-filter water purifying system that has oxygenation and backwashing function concurrently provided by the invention is made up of unpowered bio-filter and second pond, it is characterized in that: top, biological filter opening communicates with atmosphere, top, biological filter is biological filtrating area, the bottom is the sludge settling district, is provided with biofilter material, filtrate supporting, siphon back flushing oxygenation sleeve pipe, back flushing rising pipe, water inlet and rising pipe in the biological filter.
The water-in of described unpowered bio-filter links to each other with the cone-shaped sludge settling district of its underpart, the filtrate supporting is between biofiltration district and sludge settling district, siphon back flushing oxygenation sleeve pipe is positioned at the centre in the filtrate supporting and is surrounded by biofilter material, the water outlet of siphon back flushing oxygenation telescopic upper edge and biofilter material layer top maintains an equal level, siphon back flushing oxygenation telescopic lower edge is positioned on resting support eats dishes without rice or wine, the back flushing rising pipe is drawn in cone-shaped sludge settling district, and treated water outlet is positioned at the top of biofiltration district filter material layer.
The biofilter material of described unpowered bio-filter comprises Wingdale, rhombspar, rubble frame grogs and quartzy sand grains, and biofilter material is from coarse to fine, layering is from bottom to top laid.
The operation scheme of described unpowered bio-filter water purifying system: pending sewage flows into the bottom of unpowered bio-filter from top to bottom through water inlet pipe, then in the process that is upward through the biofiltration district that forms by Wingdale, rhombspar, rubble frame grogs and sand grains, be purified, purify waste water and discharge through water outlet by the top of biofilter material layer.Behind the process certain hour, because the microbial film on biofilter material surface thickens and has stopped up the intergranular water hole of biofilter material crack, effectively filter section and reduce the filtration resistance increase, make the water level in the siphon back flushing oxygenation sleeve pipe rise to priming level, cause back flushing to take place, at this time speedup takes place from top to bottom and flows in the water in the biological filter, biological residue in the biological filtering layer hole is taken out of through the back flushing rising pipe, thereby the oxygen in the atmosphere was inhaled into biological filtering layer and realized that oxygenation and filter material surface upgrade this moment.When the siphon water outlet made water level in the biological filter be lower than siphon back flushing oxygenation sleeve pipe lower edge, siphon was destroyed, and corresponding filtering layer begins to recover works better again.This process circulates repeatedly and carries out, thereby realizes the lasting purification of sewage.The back flushing water outlet is carried out solid-liquid separation at second pond, the supernatant liquor qualified discharge, and residual sludge is back to the grass green ground of woods as organic fertilizer.
In order to realize the purifying treatment to higher concentration sewage, native system also can be used as an independently water purification unit, the use of can connecting of a plurality of unit.
The present invention compared with prior art has following effect:
1. purifying water effect is stable, and effluent quality is good;
2. energy-conservation, realized unpowered oxygenation and back flushing;
3. construction investment is few, and working cost is low;
4. simple in structure, operational management is convenient.

Embodiment
Below in conjunction with drawings and Examples water purification process of the present invention is further described:
Referring to accompanying drawing 1, a kind of unpowered bio-filter water purifying system that has oxygenation and backwashing function concurrently of the present invention is made up of unpowered bio-filter 1 and second pond 2, the sewage of processing to be clean flows into the cone bucket 4 of unpowered bio-filter bottom from top to bottom through water inlet pipe 3, then through the biofilter material layer 6 that supporting on 5 to upwelling, sewage among filtering layer via numerous bacteriums, the microbial film that algae and zooplankton are formed and the purification transfer function of food chain, organic compound in the sewage and nitrogen, nutritive substances such as phosphorus are by mineralising or decompose synthetic new organic suspension material, realize purification through microbial film absorption and the effect of filtrate physical filtering again.
Described biofilter material 6 is made up of Wingdale, rhombspar, rubble frame grogs and sand grains, and biofilter material has the effect that neutralization is stablized the saprobia chemical property and biological essential nutrient element is provided.
Described a kind of automatic aeration and backwash process that has the unpowered bio-filter water purifying system of oxygenation and backwashing function concurrently is: siphon back flushing oxygenation sleeve pipe 7 has been formed the siphon back-purge system with back flushing rising pipe 8, along with being on the increase of biological filtering layer 6 surfaces and inner containing filth amount, the mistake water resistance of biological filtering layer 6 strengthens thereupon, water level in the siphon back flushing oxygenation sleeve pipe 7 is risen, when water level rose to the crest of weir of siphon back flushing oxygenation sleeve pipe 7, siphon formed.During back flushing, the biological residue in the biological filtering layer hole is taken out of through the back flushing rising pipe, realizes that oxygenation and filter material surface upgrade thereby the oxygen in the atmosphere is inhaled into biological filtering layer.When the siphon water outlet made water level in the biological filter be lower than siphon back flushing oxygenation sleeve pipe lower edge, siphon was destroyed, and corresponding filtering layer begins to recover works better again.This process circulates repeatedly and carries out, thereby realizes the lasting purification of sewage.
The back flushing water outlet is carried out solid-liquid separation at second pond 2, the supernatant liquor qualified discharge, and residual sludge is back to the grass green ground of woods as organic fertilizer.
Described a kind of unpowered bio-filter water purifying system that has oxygenation and backwashing function concurrently also can be used as an independently water purification unit, the use of can connecting of a plurality of unit, thus can realize purifying treatment to higher concentration sewage.
