Description
Technical field
The present invention relates to sewage disposal technologies more particularly to a kind of for the slow-release material of sewage treatment and its preparation side
Method.
Background technique
In recent years, with the fast development of economic society, at the decentralized type sewage for solving the problems, such as Rural Plane Source Pollution
The total nitrogen load of reason system is increasing.However, although in China's pollutant emission standard total nitrogen concentration the upper limit (level-one A mark
Standard is 15mg/L) much higher than maximum permissible value (respectively 3mg/L and 8mg/L) as defined in USA and EU, but distributing is dirty
The water outlet total nitrogen of water treatment system is still higher, and a large amount of nitrogen nutrition salt is exhausted into environment water, causes water body not
With the eutrophication of degree；On the other hand, it is super that nitrate content all occurs in the underground water that many areas are used as drinking water resource
Target phenomenon.Above-mentioned phenomenon just with the increase of nitrogen fertilizer in agriculture usage amount, the increasing of town and country sewage and house refuse discharge amount and
Constantly aggravation.
For sewage treatmentmethod, primarily now there are centralized sewage treatment and decentralized type sewage processing.And in rural area dirt
During handling sewage in particular with biofilm, easily there is water-inlet carbon source deficiency, causes denitrification de- in water treatment field
Nitrogen lacks the case where carbon source, seriously affects total nitrogen removal effect.Traditional solution is additional carbon to guarantee treatment effect,
But rural sewage treatment device distribution is wider, and the fluctuation of influent quality water is larger, additional carbon higher cost and be easy to cause two
Secondary pollution.
Summary of the invention
To solve the problems, such as that country sewage water-inlet carbon source deficiency causes denitrification effect poor, the present invention provides one kind for dirt
The slow-release material and preparation method thereof of water process denitrogenation, goal of the invention provide the material for preparing solid slow-release carbon source for denitrification process
Material.
The purpose of the present invention is implemented with the following technical solutions:
A kind of slow-release material for sewage treatment, material include PBS particle, CaCO3Filler parent granule, carbon dust and glass
Dimension, the quality proportioning of each component are 30%~60% PBS particle, 30%~40% CaCO3Filler parent granule, 5%~10%
Carbon dust and 5%~25% glass dimension.
Preferably, the length of the glass dimension is 4~8mm.
Preferably, the diameter of the PBS particle is 2~6mm.
A kind of preparation method of the above-mentioned slow-release material for sewage treatment, method include:
Firstly, by glass fiber axis；
Then, by PBS particle, CaCO3The each component of filler parent granule, carbon dust and glass dimension mixes in proportion；
Secondly, cast hopper is added in each component material of mixing；
Finally, each component material extrusion molding of the mixing in cast hopper is formed slow-release material in processing temperature by molding machine
Product.
Preferably, the processing temperature is 115 DEG C~180 DEG C.
Compared with prior art, the beneficial effects of the present invention are: the slow-release material raw material are easy to get, and the processing is simple, use
The proportion of science, so that finished material is as denitrification carrier, stability is strong, and enzymatic release, hidden danger without secondary pollution can be sustained
It is that sewage treatment provides carbon source, effect is lasting and stablizes.
Detailed description of the invention
Fig. 1 is the preparation method flow chart of slow-release material.
