Abstract
The invention provides a method used for disposing the underground seawater used for aquiculture and breeding. An aeration process is carried out for pumped underground seawater to oxidize low valence heavy metal ions in the water so as to raise valence. The aeration oxidization requires the following conditions: the removed dissolved-oxygen required by the heavy metal is greater than the heavy metal content by 0.42 times. The oxidization process is as follows: the underground seawater passes through a bilge ejector for aeration and a pipeline mixing device to lead the underground seawater to be thoroughly mixed with air in the pipeline mixing device; the oxidized and valence-raised high valence iron and manganese, etc. heavy metal ions are absorbed and filtered for removal through the filtering layer of a filter; the quality of the underground seawater which is processed through a microorganism processing reaches the quality standard of natural seawater. The processed underground seawater is suitable for the aquiculture and breeding of marine products.
Description
Technical field
The present invention relates to a kind of underground sea water process method, particularly a kind of aquaculture and underground sea water process method of growing seedlings of being used for.
Background technology
The resource of the coastal underground sea water of China is extracted with the method for beating motor-pumped well usually than horn of plenty.Underground sea water is because water temperature is more constant throughout the year; the breed of relatively suitable fishery products and growing seedlings; especially can save a large amount of fire coals in the winter of northern China and promote temperature of cultivation, the development and use of underground sea water are effective ways of energy-saving and emission-reduction protection environment.But underground sea water other indexs except temperature advantage all are unsuitable for aquaculture and grow seedlings, its complicated component, heavy metal content is higher, especially the content overproof of iron and manganese is tens times and even tens times, very harmful to aquaculture organism, moreover the biological activity difference of underground sea water causes disadvantages such as aquaculture organism poor growth, surviving rate be low.
Summary of the invention
Technical problem to be solved by this invention provides a kind of aquaculture and underground sea water process method of growing seedlings of being used for, utilize the long-term homothermic advantage of underground sea water, solve the drawback of heavy metal content height such as underground sea water iron, manganese, biological activity difference, underground sea water is used for aquaculture and grows seedlings, thereby reach energy-saving and emission-reduction and the purpose that improves the aquaculture economic benefit.
In order to address the above problem, the present invention has adopted following technical scheme.
A kind of aquaculture and underground sea water process method of growing seedlings of being used for is characterized in that:
(1), the underground sea water of Chou Quing comes the low price heavy metal ion in the oxidizing water to make it rise valency by aeration, the aeration oxidation requires to meet the following conditions: remove the required dissolved oxygen amount of heavy metal 0.42 times greater than heavy metal content, the technology of oxidation is: underground sea water makes underground sea water contact with air thorough mixing in line mixer by a water sprayer waterfall gas and a pipeline mixing device;
(2), the heavy metal ion such as high price ferrimanganic that rise valency through oxidation are adsorbed, are held back and remove by the filtering layer of strainer;
(3), make the water quality of underground sea water reach the water quality of nature seawater by the microorganism activation treatment.
Positively effect of the present invention is: by heavy metal ion such as deironing, manganese, solved the high problem of underground sea water heavy metal ion content; Solved the problem of underground sea water biological activity difference by the microorganism activation.Optimized the water quality of underground sea water, made the water quality of underground sea water reach the water quality of nature seawater, the breed of the suitable fishery products of treated underground sea water and growing seedlings.
Adopt the present invention in underground sea water, to charge into than common process more air, can also increase the solubleness of oxygen in water simultaneously.
Description of drawings
Fig. 1 is the process flow sheet of the embodiment of the invention.
Embodiment
Further specify the present invention below in conjunction with specific examples.
Underground sea water comes the heavy metal ion such as iron, manganese in the oxidizing water to make it rise valency by aeration, and the aeration oxidation adopts water sprayer and line mixer to finish; Remove the required dissolved oxygen amount (mg/l) of heavy metal 0.42 times greater than heavy metal content (mg/l).
Come heavy metals such as ferrimanganic in the planar water through the underground sea water of the oxidation filtering layer by strainer, the filtrate of filtering layer adopts double-layer filter material, and the upper strata is a quartz sand filter media, and lower floor is the manganese sand filtering material, filtrate is the medium of catalytic oxidation simultaneously, during water process filtering layer, the ferrous iron in the water is adsorbed by filtrate, and then oxydrolysis, generation has the activity " filter membrane " of katalysis, under the katalysis of " filter membrane ", the oxygenizement of heavy metals such as iron and manganese is accelerated greatly, and then is removed by filtrate.
Last ammonia nitrogen and the carbonic acid gas that reduces underground sea water again through the microorganism activation treatment improves pH value, makes the water quality of underground sea water reach the water quality of nature seawater.Microorganism activation is that the biofilm by aeration and biofilter material realizes that biofilter material normally adopts penetrating rate 〉=90%, Φ 150 * 0.5mm, and specific surface area is 296m
2The elastic biological filtrate, microorganism activatory aeration link adds micropore aeration pipe by gas blower and forms.
The processing condition of microorganism activation treatment are: aeration rate satisfies the oxygen consumption demand of aerobic microbiological, and the underground sea water DO 〉=5mg/ after promptly handling gets final product, and microorganism has enough carriers to come biofilm, and the specific surface area of carrier should be more than or equal to 50 times of aquifer yield, i.e. 1m
3The specific surface area of the aquifer yield carrier of/h should be greater than 50m

Specific embodiments example one
Adopt the integrated built-up type single-valve filter of Steel Concrete structure, the water inlet pipe in filter tank is served as by line mixer, water sprayer is installed in line mixer is carried out the aeration oxidation, water after the aeration oxidation is in diversion box partly enters the filter tank part, two-layer filtrate is housed in the part of filter tank, the upper strata is a quartz sand filter media, lower floor is the manganese sand filtering material, water after the filtration enters the filtered water tank part, in the filtered water tank part micropore aeration pipe and biofilter material are set, the water leg of water on filtered water tank after handling at last flows out, and maximum is 120～400m by discharge
3/ h.Its technical process such as Fig. 1.
The suitable relatively large aquafarm of the characteristics of the present embodiment, the flow of back flushing can Artificial Control, relatively water-saving and the loss that prevents filtrate.
Specific embodiments example two
Adopt glass reinforced plastic valveless filtering pool separated structure, the water inlet pipe in filter tank is served as by line mixer, water sprayer is installed in line mixer is carried out the aeration oxidation, water after the aeration oxidation directly enters the glass reinforced plastic valveless filtering pool and carries out Filtration Adsorption, the water that the glass reinforced plastic valveless filtering pool flows out enters follow-up independent microorganism activation pond again and carries out activation treatment, and glass reinforced plastic valveless filtering pool maximum is 30～150m by discharge
