Description
Technical field
The utility model relates to a kind of aquaculture wastewater treatment facility.
Background technology
Aquaculture is the important industry of China's rural development.In the last few years, along with the continuous expansion of cultivation scale, the sharply increase of raising quantity, a large amount of swine manure wastewaters is made to become source of pollution, the pollution that these plants produce is as can not get timely process, high risks will be caused to environment, cause the deterioration of the ecological environment, animal products quality declines and jeopardize HUMAN HEALTH, the delayed of aquaculture pollutant abatement technology will seriously restrict the Sustainable development of aquaculture.Feature that aquaculture wastewater has typically " three high ", that is: CODcr is up to 3000-12000mg/L, and ammonia nitrogen to exceed standard decades of times up to 800-2200mg/L, SS.Be limited to the small profits industry of aquaculture, treatment process is only for the significantly reduction of CODcr, and the qualified discharge problem to entirety, remain in very large technical difficulty.
Current aquaculture wastewater treatment facility is all adopt oxidation ditch+A/O technique, although can remove most COD cr and BOD5 substantially; But CODcr and BOD5 value still higher effluent quality does not reach country " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one-level A standard.
Summary of the invention
The purpose of this utility model is to provide a kind of aquaculture wastewater treatment facility, and effluent quality of disposing of sewage directly arrives emission standard.
In order to solve the problems of the technologies described above, the utility model provides aquaculture wastewater treatment facility to be achieved in that
A kind of aquaculture wastewater treatment facility, described aquaculture wastewater treatment facility comprises: water tank and base, and described water tank is divided into: grid area, acidication district, membrane biological reaction district, ozone oxidation district, settling region and clear water zone; Described grid area comprises: grid; Described acidication district is provided with filler support and lift pump, and described lift pump is below in described acidication district, described filler support is 3 D elastic filler, is connected between 3 D elastic filler by peg; Described membrane biological reaction district is provided with plate film assembly and micro-hole aerator; Described ozone oxidation district is provided with ozonation aerated device and reflux pump; Described lift pump is connected with described reflux pump; Described micro-hole aerator is connected with the outlet of gas blower.
