Description
Technical field
The present invention relates to a kind of method that utilization mudflat sludge prepares artificial algal reef.
Background technology
Increasingly the decline of fishery resources, International Fisheries agreement signature, aquatic products demand it is increasingly vigorous, promote coastal waters
Fisheries resources conservation and the development resumed work, the carrying out of transferring fishermen's job, and the industry fishery with artificial marine habitat as core
Build, be increasingly becoming one of the important channel for alleviating this series of problems.Artificial algal reef as artificial marine habitat one kind, be in order to
Improve marine algae growing environment, the underwater structures thing that propagation protects fishery resourses and sets.The making material of algal reef is various more
Sample, its adhesion effect and aggregation performance are also each variant.It is more recycling discarded or low based on environmental protection and economic theory
Value material is gradually used, and such as effectively forms unit algae place using rope, heavy stone, the marine algae low-value materials that are easy to get,
And then constitute the artificial algae field of large area；Add different amounts of iron powder or iron filings respectively in a certain amount of concrete, analyze people
The influence of work algal reef iron-holder to aufwuch etc..And land discarded object is used as reefs material, to a certain extent
Concrete material is substituted, can dissolve substantial amounts of discarded object again.
At present, trend has been increasingly becoming in research of the method at home and abroad on artificial algal reef material, such as using metallurgical
Slag, nano-tailings can prepare the Artificial fish reef concrete of high intensity；Using coal ash manufacturing artificial reefs come instead of traditional coagulation
Native reefs, its mixture is free from side effects to marine environment, and melts sulphur, copper smelter slag and flyash at 150 DEG C, is made
Sulfur curing compared with alkalescence concrete be more easy to allow algae to adhere to；The experiment of shell reef proves, algae attachment thereon
Effect is no less than natural reef, a large amount of burials of shell is so also solved to a certain extent or is put aside as useless.
Therefore, technology and theory based on such raw material manufacture of intraocular algal reef, may be implemented in protection land resources and environment
While avoid artificially processing recontamination of the discarded object to environment.There is vast coastline in China, possesses abundant containing a large amount of
The Tidal Flat Resources of nutriment.In addition to part argillo arenaceous beach is used for the cultivation such as intertidal shellfish, still there is substantial amounts of deposition to become silted up
Shale beach is difficult by.Substantial amounts of nutriment is rich in flat sedimentation mud, if will the wherein organic matter such as nitrogen, phosphorus and people
The breeding of work algae is effectively combined, and certainly will help speed up the structure process of artificial algae field.
The content of the invention
The present invention proposes a kind of method that utilization mudflat sludge prepares artificial algal reef.
A kind of method that utilization mudflat sludge prepares artificial algal reef, it is characterised in that comprise the following steps：
（1）The larger impurity such as stone therein, shell is screened out, then fresh mud is placed in baking oven, with 80~105 DEG C of air blast
Dry 24 h to moisture content be 0.1%~1%；
（2）By the mud grind into powder after drying, screened successively with the screen cloth in 2.0,1.4,1.0 mm apertures respectively, obtained
Diameter<The thin mud powder of 1 mm；
（3）Thin mud powder is added water and do not cross more than mud one times of height of powder, quickly stirred, stand 3-7d to silt layering；
（4）Clear water layer is skimmed, the mud layer on mixture upper strata is collected, and is put into dryer, with the 50-150 DEG C of h of continuous drying 18
It is 0.1%~1% to moisture content, and then obtains mud raw material；
（5）Mud proportionally is matched somebody with somebody to postpone with cement and is mixed, form reefs.
Preferably, the mud and cement 0.3: 1,0.5: 1,0.7: 1,0.9: 1.
Preferably, the step（3）Middle time of repose is 5d.
Preferably, the step（4）Drying temperature is 100 DEG C.
Artificial algal reef prepared by the method for the invention, by adjusting the ratio of reefs gross mass shared by mud, in algal reef
P elements are added in manufacturing process, to adjust the N/P ratio in water body, the survival probability and attachment probability of algae spores is improved, promoted
Enter the growth of algae plant, it is to avoid corrosion of the seawater to concrete, improve the service life of artificial algal reef.
