Abstract
The invention relates to a compound flocculating agent, which is prepared by stirring 20-60% of polymeric aluminum ferric sulfate, 10-20% of magnesium carbonate, 5-10% of carboxymethylcellulose sodium, 5-10% of starch and 5-15% of calcium sulfate, mixing, performing ball milling, drying and sieving with a sieve with 100 meshes to obtain the white powder. The compound flocculating agent used for various sewage has the technical effects of large alumen ustum generation, little sludge amount and strong coagulative power.
Description
Technical field
The present invention relates to a kind of flocculation agent, is the flocculation agent that a kind of sewage disposal is used specifically.
Background technology
Although China environmental protection obtains positive progress, the environmental pollution situation that the situation is tense changes not yet.In the situation that fast economic growth, resources and energy consumption increase considerably, China's disposal of pollutants intensity is large, it is high to load, and discharge of major pollutant amount exceedes the environmental capacity of receiving water body.Meanwhile, own water stock number is far below international average level per capita in China, and shortage of water resources causes water pollution grows worse, and water pollutes and further aggravates again the contradiction of supply and demand for the water resource.Long-term serious water pollution problems affects the integrity of water resources utilization and aquatic ecosystem, affects body health of people, has become the great bottleneck of restriction China sustainable development of socio-economy.
For the development of propelling sewage treatment industry that can be positive, there is the new technology of large quantities of researchers chemical method in research and development sewage disposal, but have difficulty in taking a step in the research and development of flocculation agent.The flocculation agent that China is used in sewage disposal is at present the traditional flocculants such as polymerize aluminum chloride, aluminium chlorohydroxide, PAFS, bodied ferric sulfate, though cost is very low, effect is undesirable, has the deficiency that alumen ustum is little, cohesive force is not strong, sludge quantity is large.
Summary of the invention
The present invention is the weak point of improving above-mentioned existing traditional flocculant, aim to provide a kind of compound sewage treatment flocculating agent, problem to be solved is on the basis of traditional flocculant, to combine other chemical compositions, compound sewage treatment flocculating agent is retained under the prerequisite of original traditional flocculant advantage, and generation alumen ustum is large, sludge quantity is little, cohesive force is stronger.
This composite flocculant is formed by the Raw material processing of following ratio:
PAFS: 20-60% magnesiumcarbonate: 10-20%
Xylo-Mucine: 5-10% starch: 5-10%
Calcium sulfate: 5-15%
First, by the each feed composition of above-mentioned weight ratio proportioning; Secondly, in being uniformly mixed above-mentioned each component, add 5% water, continue to stir 25 minutes; Then, said mixture being sent into ball mill fully grinds; Finally, the mixture after fully grinding is sent in drying plant and is dehydrated, then filter through 100 mesh sieves, obtain the finished product.When use, every 1 ton of sewage uses 25-400g.
The effect of this water purification agent is embodied in:
1. for various sewage, the alumen ustum of generation flocs unit is large, sludge quantity is little, sludge coagulating power is stronger simultaneously, and dehydration does not need to add coagulant aids.
2. the present invention also can directly process the sewage of suspension object height.
3. composite flocculant of the present invention is white powder, is mainly made up of mineral compound, non-secondary pollution.
Embodiment
Embodiment 1: by the each feed composition of above-mentioned weight ratio proportioning, add 5% water in being uniformly mixed above-mentioned each component, continue to stir 25 minutes; Then, said mixture is sent into ball mill and fully grind, the mixture after fully grinding is sent in drying plant and is dehydrated, after 100 mesh sieves filter, obtain the finished product.
In the present embodiment 1, preferably 55 weight part PAFS, 20 weight part magnesiumcarbonate, 10 weight part Xylo-Mucines, 5 weight part starch, 10 weight part calcium sulfate.
Table 1: the simultaneous test cartogram of various flocculation agents.
Above-mentioned statistic data shows: relatively existing flocculation agent, on the indices of the present invention's pollutent in water treatment, all there is performance more by force, and its over-all properties has greater advantage.
Claims (4)
1. a composite flocculant, is characterized in that each component forms by following weight ratio:
PAFS 20-60%, magnesiumcarbonate 10-20%, Xylo-Mucine 5-10%, starch 5-10%, calcium sulfate 5-15%.
2. composite flocculant claimed in claim 1, is characterized in that its size is 100 orders.
3. a method of preparing composite flocculation agent described in claim 1, is characterized in that:
First, by the above-mentioned each component of above-mentioned weight ratio proportioning;
Secondly, in being uniformly mixed above-mentioned each component, add 5% water, continue to stir 25 minutes;
Then, said mixture being sent into ball mill fully grinds;
Finally, the mixture after fully grinding is sent in drying plant and is dewatered, then filter and obtain the finished product through 100 mesh sieves.
4. a method of disposing of sewage, is characterized in that in each ton of sewage, adding the amount of composite flocculant described in claim 1 is 25 grams to 400 grams.
