Abstract
The invention provides a water distribution method of earthworm bio-filter, which belongs to an environmental protection technical sphere. In the invention, setting a buffer basin before sewage flowing into earthworm bio-filter, wherein hydraulic sensor and a water pump located to adjust water inflow; carrying out pre-aeration before distributing water to filter; distributing water with water-distribution hydrovalve above filter, a pressure modulation switch on the hydrovalve, the switch , the hydraulic sensor and the pump controlled by computer program; the surface of filtering material in the filter divided into trench and mountain; according to the growth trait of earthworm and microbe population, setting interval of water-distribution time and water inflow each time, to coordinate water inflow with earthworm population. The invention not only realizes maximum sewage treatment capacity of earthworm bio-filter, but also makes the filter operate relative stably.
Description
Technical field
What the present invention relates to is a kind of method of environmental technology field, specifically is a kind of water distribution method for earthworm biofilter.
Background technology
Worm biological filter tank is a new sewage disposal biotechnology, is to introduce the organic decomposition processing layer that includes specific earthworm kind on the basis of ordinary biofilter.Because earthworm has the organic substance of eating, it is (permeable to improve soil permeability, ventilation) and with microorganism synergy promote the ecological functions such as degraded of organic substance, therefore, can improve the voidage of filtrate, promote the degraded of organic substance in the sewage, and remove the sludge blockage phenomenon that may occur in the filter tank, thereby improve the processing power and the processing efficiency in filter tank.The introducing that earthworm is filtered decomposition layer has not only improved the disaggregating treatment efficient of organic pollutant in the sewage, but also has overcome this important disadvantages of ordinary biofilter sludge blockage in service.Worm biological filter tank also has certain denitrification dephosphorization function simultaneously.
Worm biological filter tank is different from ordinary biofilter, thereby its water distribution method is also inequality.Should enough sewage treatment capacity be arranged the filter tank, again can not be excessive, in order to avoid earthworm is caused murder by poisoning.
Through new to looking into of prior art, find as yet with theme of the present invention at the identical or similar bibliographical information of the method for Worm biological filter tank water distribution.
Summary of the invention
The objective of the invention is at the Worm biological filter tank technology of disposing of sewage, a kind of water distribution method for earthworm biofilter is provided, make it both guarantee that there were enough sewage treatment capacity in the filter tank, can make earthworm and microorganism in the filter tank that suitable living environment is arranged again, to guarantee the normal operation in filter tank, improve the wastewater treatment efficiency of Worm biological filter tank.
The present invention is achieved by the following technical solutions, and the present invention at first is provided with a Buffer Pool before sewage enters Worm biological filter tank, hydraulic pressure sensor and water pump wherein are installed, to regulate flooding quantity; Before the water distribution of filter tank, carry out preaeration earlier; Water distribution is undertaken by the cloth water tap of top, filter tank, and this cloth water tap has the air pressure regulating switch, controls by computer program with hydraulic pressure sensor and water pump in the Buffer Pool; The filter material surface of Worm biological filter tank is divided into ditch and ridge; Population upgrowth situation according to earthworm in the filter tank and microorganism is provided with the water distribution timed interval and each cloth water yield, and the cloth water yield can be coordinated with the earthworm population.
Described Buffer Pool promptly passes to computer by sensor with information, controls the water pump size of the cloth water yield in the earthworm filter tank at every turn by computer.
Described preaeration is to feed pressurized air in Buffer Pool, in order to avoid lack of air and cause earthworm or microbial death.
Described cloth water tap is a kind of water-distributing device that aims at the earthworm filter tank and design, and the water distribution scope is about 3m
2, from the high about 1m of filter material surface of Worm biological filter tank, water distribution uniformity coefficient height.
Described air pressure regulating switch is by pressurized air control, and by the program auto-control, when the needs water distribution, switch open to the filter tank water distribution, is closed in the time of intermittently.
The filter material surface of described Worm biological filter tank is divided into ditch and ridge, and the bottom width of ridge is about 0.5m, highly about 0.3m.When water in the sprinkling process can not flow away rapidly, earthworm can perch in ridge.
The present invention realizes the coordination of water distribution and earthworm population by time variable control.When the filter tank brought into operation, the cloth water yield was less relatively, and sewage treatment capacity is relatively low; Along with the growth of earthworm population, the cloth water yield also increases thereupon, the also corresponding raising of sewage treatment capacity.So both realized the maximization of Worm biological filter tank processing power, the filter tank can be moved relatively stablely.
Description of drawings
Fig. 1 the inventive method schema
Embodiment
As shown in Figure 1, the invention process step is as follows:
1. a Buffer Pool is set before sewage enters Worm biological filter tank, hydraulic pressure sensor and water pump wherein are installed, information is passed to computer, control the water pump size of the cloth water yield in the earthworm filter tank at every turn by computer by sensor.
2. feed pressurized air in the Buffer Pool, in order to avoid lack of air and cause earthworm or microbial death
3. according to the population upgrowth situation of earthworm in the filter tank and microorganism the water distribution timed interval and each cloth water yield are set,, thereby reach best wastewater treatment efficiency so that earthworm and microorganism keep best living environment in the filter tank.
4. pass through the cloth water tap to the filter tank water distribution by programmed instruction, the filter tank is moved continuously.
Providing embodiment below in conjunction with content of the present invention, is example with certain pig farm Worm biological filter tank Sewage treatment systems, and its water distribution method is as follows:
Entering sewage before the Worm biological filter tank, to be stored in a volume earlier be 1m
3Buffer Pool in, Xiang Chizhong feeds pressurized air to carry out preaeration.Earthworm population in the filter tank is from 0.4 ten thousand/m
2To 20,000/m
2In the process that increases, according to the upgrowth situation of the population of earthworm, the sewage loading by computer programming is from 6L/m
2. inferior, every day 6 times, be increased to 15L/m gradually
2. inferior, every day 6 times.Earthworm population growth is very fast like this, and growing environment is preferable, makes the sewage treatment capacity in filter tank reach the best.The filter tank operation conditions is good, the phenomenon of earthworm death even filter tank collapse do not occur.
