Abstract
The invention discloses a suspended biological bed minitype domestic sewage treatment system which converts the traditional perforated pipe water distribution mode into the ditch water distribution mode. The system is characterized by comprising at least three water distribution system stages, namely a biological bed first section (1), a biological bed second section (2) and a biological bed third section (3), wherein a pipe network is connected with the water distribution system, a plurality of water distribution ditches (4) are buried in the filler layer, and each ditch top is provided with a porous water distribution board. By adopting the physical method and biological method, the sewage is treated by a pretreatment system (composed of a grid tank and an anaerobic fermentation tank) and enters the water distribution system in which the water distribution system is buried; and after entering the water distribution system, the sewage naturally permeates to the filler layer along the two sides of the water distribution ditches, so that SS (suspended sediment), COD (chemical oxygen demand), N, P and other pollutants carried in the sewage can effectively removed under the absorption action of the plant rhizomes and the trapping action of the filler. The system is divided into multiple stages, thereby enhancing the sewage purification efficiency.
Description
Technical field
The invention belongs to sewage disposal device, be specifically related to a kind of suspending type biological bed small-sized domestic sewage processing system.
Background technology
Industry situation: artificial swamp is a kind of biological wastewater treatment technology growing up phase late 1970s, the flow pattern difference according to sewage in wetland can be divided into artificial wet land system surface current artificial wetland, drowned flow artificial wet land and vertical current constructed wetland three types.In artificial swamp, water distribution uniformity is vital content, and whether whether water distribution is evenly directly connected to wetland can steady running.Only have water distribution uniformity, can guarantee that the load of same one-level treatment system is consistent, prevent the generation in short-circuit flow and dead band, thereby reach desirable treatment effect, this is one of the primary condition that can normally move of wetland.Different water flow modes and water distribution manner have different treatment effects, good water distribution manner can improve the processing efficiency of wetland, undesirable water distribution manner makes the Efficiency Decreasing of wetland, easily there is short stream and obstruction, therefore wetland is carried out to the performance that effective water distribution can improve wet land treating system, the construction of wetland water distribution system is extremely important to the processing power of enhancing wetland.
Similar techniques research both at home and abroad, exploitation present situation, the subject matter of existence and Near-future Development Trend:
The design of artificial swamp water inlet system should guarantee the homogeneity of water distribution as far as possible, generally adopts perforated tube or V-notch weir etc.Perforated tube is located on soil surface or is embedded in below soil surface, and the shortcoming being embedded under soil surface is that water distribution regulates comparatively difficulty.When perforated tube is located at bed surface top, should exceed 0.5m left and right than bed surface, in case bed surface mud and weeds accumulate, affect water distribution.Answer periodic cleaning throw out and weeds etc. simultaneously, guarantee the homogeneity of system water distribution.The flooding velocity of system can regulate by valve or flashboard, and takes overflow, shunting measure to tackle paroxysmal fluctuations in discharge should to have overflow, shunting measure.Artificial wetland effluent system adopts the modes such as ditch row, pipe row, well array, the former factor such as have ready conditions that rational design should be considered the feature of receiving water body, the layout of wet land system and place.
For effectively controlling wetland water level, generally in packing layer bottom, establish perforation header, and turning gland and by-pass valve control are set.To severe cold area, arranging of inlet tube and outlet tube must be considered antifreezing measures, and at the necessary position of system, control valve and blow-off valve is set.
Summary of the invention
The object of the present invention is to provide a kind of suspending type biological bed small-sized domestic sewage processing system, it is irrigation canals and ditches water distribution that this system changes traditional perforated tube water distribution manner, can effectively solve on the one hand water distribution and regulate the series of problems bringing, on the other hand, can effectively prevent that the line clogging that perforated tube water distribution system brings from causing effluent quality variation, even systemic breakdown.The present invention adopts irrigation canals and ditches water distribution system, and its water distribution tradition water distribution system is more even; The present invention accomplishes zero annex, the problems such as water quality variation that can effectively avoid system to cause because of each system attachment fault.
Object of the present invention and solve its technical problem underlying and realize by the following technical solutions: a kind of suspending type biological bed small-sized domestic sewage processing system, changing traditional perforated tube water distribution manner is irrigation canals and ditches water distribution, comprise at least three grades of water distribution systems, be three sections of one section of biological bed, two sections of biological beds and biological beds, pipe network connects water distribution system, a plurality of cloth water channels are embedded in packing layer, and canal top is porous water distribution board.
Described water distribution system specification is B * H=300 * 800mm.
The technology of the present invention principle: adopt Physical, biological process, sewage enters in water distribution system after pretreatment system (grating tank, anaerobically fermenting pond) is processed, water distribution system is embedded in packing layer, sewage enters after water distribution system, nature permeates toward packing layer along cloth water channel both sides, the pollutents such as the SS carrying in sewage, COD, N, P, due to the absorption of plant roots and stems, the crown_interception of filler, are effectively removed.System is divided into multistage, thereby improves the purification efficiency of sewage.
The present invention compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the present invention has following basic mechanical design feature:
A. effectively remove the pollution substance such as contained SS, COD, N, P in sewage,
B. the cloth facility that catchments is unobstructed, does not have latch up phenomenon,
C. engineering construction difficulty is less, simple to operate,
D. later maintenance expense is low,
E. energy consumption is low,
F. stable.
