Abstract
The invention discloses a kind of preparation method and applications of the filler biological floating bed applied to combined type triple effect, to improve the purification of water quality ability of existing biological floating bed matrix and nutrient supply performance.The filler is combined by hard solid filler A and polyurethane sponge soft-filler B.Preparation process includes dispensing, mixing granulation, drying, curing, cooling, composite foamed.Raw materials used cheap, production method is simple, and the filler of gained has the advantages that specific surface area is big, porosity is high, microorganism colonization performance is good, denitrogenation dephosphorizing ability is strong.By applying filler in combined type triple effect is biological floating bed, removal ability of the ecological floating bed device to Water phosphorus nutrition element can be drastically increased, and filler has nitrogen phosphorus sustained release performance, the nutrient supply environment of stabilization can be provided for plant growth, it is highly suitable for the purified in situ processing of eutrophication water, the especially purification of agricultural non -point pollution water body.
Description
Technical field
The invention belongs to water treatment field, and in particular to a kind of compounded mix biological floating bed applied to combined type triple effect
Preparation method and applications.
Background technology
Biological floating bed is a kind of water body in-situ recovery technique risen in recent years.At present, the technology is in lake eutrophication water
It is widely used in the purification of body and fishery cultivating waste water.The technology has without taking up an area, cheap, easy for installation, reparation
The characteristics of effect is good, operational management is simple.
By years of researches and practice, researcher has found traditional following deficiency of biological floating bed presence：(1) root system of plant
