Background technique
With China's ocean development implementation, the rise that island tourism is gone sightseeing, resident on China coast island and
Tourist gradually increases, and not only causes the shortage of freshwater resources on island, can also generate mass production, sanitary sewage.And island is
One relatively independent Eco-Environment System does not have the sewage collecting pipe network of architectonical generally yet, if not to the dirt of generation
Water handled and in the seawater near being directly discharged to, will affect island environmental carrying capacity and water body to sewage from net energy
Power, this is harmful for the sustainable development on island and ocean.Therefore, reinforce having become sea to the improvement of island sewage
Urgent problem to be solved during the development & construction of island.
Chinese invention patent CN108128984A discloses a kind of island dispersant type domestic wastewater processing system, including the sun
Energy system, turn-key system, pretreatment unit, ABR reaction tank, conditioning tank, biological contact oxidation pond, sludge drainage system.Island life
Sewage can reach qualified discharge after the system processing by the invention.Although the invention can use the solar energy and wind on island
It can run and be used for processing system, biogas can also be generated.But that there are sources is unstable, cannot continue for wind energy and solar energy
The defect steadily produced electricl energy.
Chinese utility model patent CN204022559U discloses island sewage integrated treatment device, including anoxic zone,
Aerobic film area, discharge region and operating space, wherein sludge pipe and phegma cloth sink, the aerobic zone are equipped in the anoxic zone
Interior to be equipped with MBR membrane module, tubular type aerating system and reflux cycle air-lift device, top is logical between the anoxic zone and aerobic film area
Cross return pipe connection；The operating space includes power control cabinet, film running gear, elevator pump and blower；The one of the film running gear
End is connected with MBR membrane module, another to be connected to clear water zone；The promotion pump discharge is connected to the phegma cloth sink in anoxic zone；
The blower is connect with tubular type aerator.The island sewage integrated treatment device that the utility model provides is lacked by being arranged
Oxygen area and aerobic film area two parts biochemical treatment apparatus, top is connected to by return pipe between the anoxic zone and aerobic film area,
Different backflow functionalities is realized by valve regulated, has both activated sludge process and MBR advantage.But it is the need for stable power supply to supply
It just can should continually and steadily run, if the condition on island cannot be guaranteed the lasting supply of power supply, the operation of the system can
Impact can be encountered, to influence treatment effect, in some instances it may even be possible to will lead to the collapse of biological treatment system.
Therefore, it develops a kind of while utilizing water energy and methane energy, the energy is provided for processing system, without external energy
Island sewage can be effectively treated in source, its qualified discharge is made not pollute the processing technique of neighbouring water body, with important society's effect
Benefit and Significance for Environment.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of integrated effluent disposal systems suitable for island, should
System can use water energy and marsh gas power generation, and water supply processing system uses, and the production and living generated on island can be effectively treated
Sewage realizes treatment in situ, is conducive to environmental protection.
The specific technical solution that the present invention solves above-mentioned technical problem is as follows:
A kind of integrated effluent disposal system suitable for island, including miniature hydro-power generation system, sewage disposal system,
Methane power generating system, general control system, wherein miniature hydro-power generation system include drainage device, water wheels, rotary shaft, generator,
Rack, battery, water wheels are connect with drainage device, and rotary shaft is located at immediately below water wheels and connect with water wheels, and water wheels pass through rotation
Axis drives generator, and generator is set on rack；Sewage disposal system includes mud discharging device and sequentially connected spiral-flow type
Setting pot, conditioning tank, anaerobic pond, the pond MBR, clear water reserviors；Methane power generating system includes gas storage holder, moisture trap, marsh gas power generation
Unit.
Further, the generator is connect with the battery, and the drainage device is connect with the clear water reserviors, and
At 1~3m below clear water reserviors.
Further, the drainage device is successively arranged drainage tube, helix tube, and the water wheels are located at helix tube center, institute
The water outlet for stating clear water reserviors enters helix tube by drainage tube, and water wheels rotation is pushed to generate electricity.
Further, the pond MBR is equipped with aerobic MBR membrane bioreactor, and using blast aeration, dissolved oxygen concentration is
5.0~10.0mg/L, hydraulic detention time are for 24 hours；The every operation 30min of membrane module stops 15min.
Further, liquor natrii hypochloritis is added in the pond MBR, concentration is 30~120mg/L, preferably 70mg/
L；The pond MBR is additionally provided with dissolved oxygen sensor, connect with general control system.The general control system includes DC micro electricity
Brain.
Further, the generator, Biogas Generator Set are connect by current inductor with general control system, described
Biogas Generator Set is also connect with the battery.
Further, the mud discharging device is connect with conditioning tank, anaerobic pond, the pond MBR respectively, and mud discharging device is additionally provided with dirt
Dredge pump；Mud height sensor is equipped in conditioning tank, anaerobic pond, the pond MBR, mud height sensor and general control system connect
It connects.
Further, the anaerobic pond is connect by collecting methane pipe with the gas storage holder, the moisture trap point
It is not connected with gas storage holder, Biogas Generator Set.
Further, an atmospheric buffer device is also set up before the Biogas Generator Set, for stablizing biogas air pressure.
Further, the miniature hydro-power generation system and the methane power generating system can also be connected with external electric appliance
It connects.
The miniature hydro-power generation system that the present invention uses, with the clear water reserviors there are certain difference in height, when water flow from
Clear water reserviors flow to miniature hydro-power generation system, and water wheels rotation is pushed to generate electricity, that is, realize gravitional force conversion for electric energy.
The present invention is there are also other set electric power supply system, i.e. methane power generating system, when the biogas that anaerobic pond generates enters gas storage holder, passes through
