Mixed ecological filling mainly comprising modified molluscs, composite filling sphere, purification tank device and preparation technology

Abstract

The invention relates to the technical field of water treatment and ecological repairing equipment and methods, in particular to mixed ecological filling mainly comprising modified molluscs, a composite filling sphere, a purification tank device and a preparation technology. The mixed ecological filling is prepared by mixing calcined mollusc mixed ecological filling, tea residue active carbon, zeolite, limestone, coarse aggregate, ceramsite and soft stone. Compared with the prior art, the filling, the filling sphere, the device and the technology have the advantages that a formula source of the mollusc mixed ecological filling is wide; the price is low; changing of wastes into valuables can be achieved; the requirements of modern green social sustainable development are met; the mollusc mixed ecological filling has larger specific surface area and high porosity, is light in weight, high in strength, stable in physical and chemical properties, and has no harmful effect on biological propagation; a double-layer structure of the filling sphere fixes the mollusc mixed ecological filling; the filling sphere is large in specific surface area and easy in biofilm formation and is not blocked; and the purification tank stabilization device has bondability and fluidity, is safe and stable and avoids a scouring problem.

Description

[technical field] [0001] The invention relates to the technical field of water treatment and ecological restoration equipment and methods, in particular to a mixed ecological filler mainly based on modified shellfish, a composite filler ball, a purification tank device and a preparation process. [Background technique] [0002] In recent years, with the development of the economy, the pollution of the river has become more and more serious. Due to the destruction of the ecosystem, the aquatic animals and plants in the river have gradually disappeared, the river has lost its self-purification ability, and the eutrophication of the water body has become more and more obvious. The eutrophication of the water body It caused the massive reproduction of algae and other aquatic plants, the decrease of dissolved oxygen in water body, the deterioration of water quality and the mass death of aquatic organisms. The control and removal of nitrogen and phosphorus, the key factors of water...
