Abstract
The invention provides a kind of waters improvement particulate material and preparation and application thereof, its feed composition: flyash 70-90%, cement 5-20%, clay 2-10%, biological enzyme 10-100ppm, water 15-30%, wherein the mass percent sum of flyash, cement and clay is 100%.The particle diameter of this particulate material is at below 5cm, many minute apertures, comparatively light, air-and water-permeable, can absorb and suppress water bottom mud to dissolve hydrogen sulfide, phosphoric acid salt and the ammonia nitrogen, degraded Organic substance in water, purify water and form good microbial environment and water-bed vegeto-animal coenocorrelation, preparation technology is simple, and raw material sources are wide, with low cost, possess significant economic and social benefit.
Description
Technical field
The invention belongs to water body treating field, be specifically related to a kind of waters improvement particulate material and preparation and application thereof.
Background technology
Mud in lake is the remains produced in water body purification process.It is a kind of coenobium of the acidic substance containing multiple oxious component, not only can not cause too many harm to water body when storage is less, also as the ultra-fine film of one deck, can stop seepage of lake water.But in lake, the existence of a large amount of mud is the important factor causing body eutrophication at present.Administering method main at present has following 3 kinds: (1) is domestic mostly adopts desilting to dredge method, and mechanical cost of labor is huge, because being one decrement for the moment, after can not controlling repeatedly.And during desilting, water pollution is serious, can not change the accumulation of the regular amount of mud.The place to go of the mud under clear is also a suitable difficult problem.(2) principles of chemistry are administered more commonly white lime and are controlled the end.But its chemical property validity period is short, the not desirable physical properties of harnessing the river.(3) cover sand method, suppress mud to the cyclic polluting of water body the shutoff that comes up that the natural grains of sand or handstone paving are pressed in mud.Due to the covering of just physical property, and the proportion of sandstone is greater than mud, easily causes on bed mud and turns over, weaken and cover sand effect in spreading.And effectively can not suppress the lasting accumulation of mud.
Summary of the invention
The object of the present invention is to provide a kind of waters improvement particulate material and preparation and application thereof, the particle diameter of this particulate material is at below 5cm, many minute apertures, comparatively light, air-and water-permeable, can absorb and suppress water bottom mud to dissolve hydrogen sulfide, phosphoric acid salt and the ammonia nitrogen, degraded Organic substance in water, purify water and form good microbial environment and water-bed vegeto-animal coenocorrelation, preparation technology is simple, raw material sources are wide, with low cost, possess significant economic and social benefit.
For achieving the above object, the present invention adopts following technical scheme:
The feed composition of waters improvement particulate material: flyash 70-90%, cement 5-20%, a clay 2-10%, biological enzyme 10-100ppm, water 15-30%, wherein the mass percent sum of flyash, cement and clay is 100%.
Described biological enzyme is one or more in proteolytic enzyme, amylase, cellulase, lipase.
Weigh each feed composition by proportioning raw materials, mix, obtain by tablets press the particle that particle diameter is below 5cm.
Described waters improvement particulate material equably spreading on the mud at the corresponding bottom needing the waters administered and the mud region of easily piling up.
Remarkable advantage of the present invention is:
(1) products material of the present invention is mainly the waste material in power station, the accumulation also eliminating waste powder coal ash while can administering water surrounding occupying and destruction to environment soil.
(2) the present invention uses product unburned thus greatly alleviates manufacturing cost save energy.Finished product specific gravity control, at 1.5-1.8, guarantees to be layered on mud and is not taken away by current easily.
(3) use the present invention can replace most of traditional consumption wealth and take time and effort, produce the desilting engineering that secondary pollution can not control to send out again, also save sludge treatment and stacking that desilting gets off.
(4) use the present invention can replace use resource day by day reduce and exploit the natural sand of welding, natural gravel cover sand engineering.Reserved resource is also cost-saving.And in environmental improvement, on physics and biochemical, be also better than natural sandstone comprehensively.
(5) particle diameter of particulate material is at below 5cm, many minute apertures, comparatively light, air-and water-permeable, can absorb and suppress water bottom mud to dissolve hydrogen sulfide, phosphoric acid salt and the ammonia nitrogen, degraded Organic substance in water, purify water and form good microbial environment and water-bed vegeto-animal coenocorrelation, preparation technology is simple, and raw material sources are wide, with low cost, possess significant economic and social benefit.
