A kind of artificial beach for the efficient sludge reefs algal starting material and its preparation method

A kind of artificial beach for the efficient sludge reefs algal starting material and its preparation method, wherein the use of beach sludge rich in nutrients content of nitrogen, phosphorus and other characteristics, with reference to the dissolution of salty mud under different nutrient substance and the mass ratio of the cement to prepare artificial algal reefs. The present invention further provides a method of preparing a raw material beach sludge, and the sludge mass to be obtained by this method accounts for 15 to 30% by mass of the total algal reef, between the compressive strength of the corresponding 25 ~ 30Mp, on the beach sludge The overall utilization rate up to 20%. The present invention continuously from the inside of the reef eluted component nutrients nitrogen, phosphorus, etc., while providing for the attachment of algae and their spores, fixing the matrix, but also for its survival, growth, provide a good nutritional environment. The invention reduces the amount of cement and other materials, reducing the alkalinity of concrete artificial reef algae, beach restoration of the natural landscape of the region is also important in the realization of energy saving, will help improve the artificial algal reefs and the marine environment compatibility.
