Technical field

The present invention relates to a kind of marine pollution processing method, especially a kind of collection method of cyanobacteria.

Background technique

With the development of society, the cyanobacteria of the inland river inland lake water surface is more and more, once the temperature rises, will largely break out, Water body and organism in water are damaged.In order to avoid cyanobacteria influences ecology and living environment, need in time to salvage it.

Existing cleaning fishing operation mostly uses " pumping to day suction inlet " directly to inhale algae, this not only makes scattered, thin indigo plant Algae is difficult to collect, even if sucking is collected by the thick cyanobacteria for accumulating in pumping hole edge naturally after pump is dispersed as algae water mixed liquid " algae " moisture content of device is still very high, gives subsequent transportation by lighter, and dehydration all causes very big difficulty, increases cost.

Summary of the invention

There is provided that a kind of dehydrating effect is good, collection efficiency the purpose of the present invention is to solve above-mentioned the deficiencies in the prior art The collection method of high cyanobacteria.

To achieve the goals above, the collection method of a kind of cyanobacteria designed by the present invention, it includes the following steps:

A. intercept and come together, by the way that the enclosing facility that fishing algae platform two sides are in herringbone expansion is arranged in, by nature stormy waves or In such a way that driving enclosing facility and fishing algae platform advance in water, make cyanobacteria along enclosing facility gradually to fishing algae platform position Set convergence；

B. overflow divides water, fishing algae platform introducing port at overflow gate the cyanobacteria of convergence and water are separated, introducing port compared with Downside is lower than the water surface, adjusts the algae water that overflow gate control enters introducing port, enters upper layer algae water through overflow above overflow gate Introducing port, lower layer's water purification are then blocked in by overflow gate outer；

C. air bearing sprays nano bubble from the lower direction algae water of introducing port, makes the suspension algae in algae water under bubble except hanging Liquid surface is floated up to, cyanobacteria continues to drift about after floating with face layer algae；The water purification separated with suspension algae then passes through drainage pump Effect is discharged to outside body of water out of fishing algae platform；

D. mixed flow waddingization spills medicine equipment by flocculant and launches flocculant into algae water, and algae water flows into mixed after mixing with flocculant It flows in waddingization device, mixed flow is carried out in the form stirred up and down to algae water and flocculant by mixed flow waddingization device, is discharged cyanobacteria broken wall, To by effective waddingization；

E. it is layered drainage, the algae slurry after mixed flow waddingization enters layering drainage storehouse by coagulation waddingization device；Algae slurry is in layering drainage It is accumulated in storehouse, pulp water therein is inhaled through the strainer exudation that layering drainage storehouse surrounding and bottom is arranged in, the part pulp water through pump It is transported at introducing port, and the cyanobacteria above introduction port is sprayed, the remaining flocculation ingredient in pulp water plays cyanobacteria The effect of pre- waddingization；

In above-mentioned steps a ~ e, the flowing of algae water is carried out by the mode of negative pressure drainage, therefore algae water is salvaged in treatment process, often Algae aqueous mixtures liquid level in one step reduces step by step with respect to previous step.

In order to further facilitate recycling, the moisture of regenerant is more fully excluded, a kind of collection method of cyanobacteria is also Include the following steps:

F. vacuum fine is de-, and by vacuum generator, the concentration algae slurry that drainage processing is passed through in step e is pumped to equipped with strainer After in closed storage tank, further layering is dehydrated into algal gel to concentration algae slurry under the vacuum pressures, and pulp water is out of closed storage tank After outflow, it is pumped together with the pulp water in step e to introducing port and is recycled.

After completing step f, the algal gel in closed storage tank can be taken out and transport.

In order to guarantee recovery efficiency, the suspension algae omitted in pulp water is reduced, it further includes as follows that the step f. vacuum fine is de- Step:

H. it offers medicine again, aspirates concentration algae slurry simultaneously in vacuum generator, flocculant is added again into concentration algae slurry, makes to be concentrated The further flocculation of algae slurry.

A kind of collection method for cyanobacteria that the present invention obtains is dehydrated cyanobacteria by multistage, circulation, is agglomerated, waddingization, Efficiently polluted water region can be cleared up, the dehydration rate being dehydrated to sewage containing cyanobacteria greatly improves, using nanometer air bearing Equipment and mixed flow waddingization device, simplify the structure of flocculation stirring equipment, without using the suction of powerful pump and agitating device, make an uproar Sound is small, at low cost, protection environment.
