Abstract
The invention provides a sludge dewatering conditioner and a preparing method and application thereof.The sludge dewatering conditioner is prepared from metallic oxides Al2O3, Fe2O3 and CaO, nonmetallic oxides SiO2 and SO3, and polydiallyldimethylammonium chloride (PDADMAC).The sludge dewatering conditioner can conduct internal conditioning on the structural performance, water character and physical and mechanical properties of sludge containing a large amount of water, so as to create an endogenic environmental condition beneficial to sludge dewatering.Quick dewatering of sludge under the condition that mechanical equipment is used is achieved.The invention further provides the preparing method of the sludge dewatering conditioner.According to the preparing method, the metallic oxides and the nonmetallic oxides are subjected to high-temperature roasting and microwave radiation to have required activity, preparation is conducted according to determined components and determined mass fractions, grinding is conducted to obtain required fineness, and a diallyl ammonium chloride solution is adopted cooperatively for preparing the sludge dewatering conditioner.
Description
Technical field
The present invention relates to sludge dewatering conditioner of sludge dewatering and its production and use in a kind of water environment field.
Background technology
Mud is the important component part of muddy water environment.It is the Fundamentals of society, economic system existence and development, the tenability of the national economic development in region is played vital effect.Due to the reason such as accumulation and recent economic construction high speed development of history, the muddy water environmental problem in the city of China more than 90% is increasingly serious.Show as the severe siltation of city river, shortage of water resources, water pollute overweight, Ecology balance and suffer destruction etc..So that the sustainable development in city is more and more seriously hampered, human settlement is increasingly subject to serious threat.
The eight large watersheds particularly Yangtze River Delta of China, Delta of Pearl River river network, along with the fast development of industrial or agricultural, a large amount of industrial and agricultural wastewaters passed through number of ways flow into river water body.Owing to the ability of hydrodynamic force with load contaminant species amount is lacked of proper care, cause pollutant to be finally deposited in Sediments, and progressively accumulation forms serious pollution siltation layer.Thus produce many rivers, there is body eutrophication in lake, and frequently the black smelly a kind of universal phenomenon become in the network of waterways, city, each basin in the wawter bloom phenomenon of generation, river course, has had a strong impact on resident living, city image and urban ecology, landscape environment.
Social economy and ecological environment and human settlements life are caused very big coercing and pressure by sludge pollution problem, and the further development in city is created bigger negative effect by river and lake silt really.Therefore, the desilting of lake, river and to " minimizing ", " innoxious ", " stabilisation " of contaminated mud, " resource " process dispose become one extremely urgent vital task of current government agencies at all levels.
If dredging lake, river relief mud natural-dehydration mummification, that will be a very very long process.Namely or adopt mechanical dehydration, owing to the effect of the water in mud and the physics adhesive tension of solid particle, chemical bond force, charge attraction power etc. causes sludge dewatering to remain an extremely difficult thing.For this, must select preparation targetedly that mud is nursed one's health before dehydration, destroy the viscous factor of solid particle and water in mud, build the environment that solid particle is easily isolated with appended moisture, so as to contained moisture can be removed as far as possible at short notice when using plant equipment, here it is the objective of the present invention.
Summary of the invention
The present invention provides a kind of sludge dewatering conditioner and its production and use for processing the water smoking disposing mud, and its function is to carrying out inherent conditioning before sludge dewatering, building the endogenous environmental condition of one contributing to mud slurry dewatering.
A kind of sludge dewatering conditioner, each component percentage meter by weight, it is characterised in that be made up of following component:
Metal-oxide Al2O3、Fe2O3, CaO, its mass component is respectively as follows: Al2O314.6～25.5%, Fe2O36.8～17.5%, CaO12.5～21.8%；
Nonmetal oxide SiO2、SO3, SiO2With SiO3 2-Form exists, SO3With SO4 2-Form exists, and its mass component is respectively as follows: SiO237.0～45.3%, SO32.5～6.5%；
PDDA (PDADMAC) 5%, total amount is 100%.
The main starting point of selection said components is: mud mud can carry out inherent conditioning, can ensure that again conditioning process and result all do not produce secondary pollution.
The preparation method of a kind of sludge dewatering conditioner, it is characterised in that sequentially include the following steps:
(1) component A
(1) metal-oxide and nonmetal oxide are pressed 1000 DEG C of 1h, 1100 DEG C of 1h, the order roasting of 1200 DEG C of 2h respectively in roaster；
(2) it is configured to compound by the component determined and mass component after each component materials cooling step (1) prepared；
(3) compound grinding machine grinding step (2) made is to specific surface area >=400m2The fine powder of/kg；
(4) fine powder that step (3) grinds is placed in radiation heating 2h in the microwave field that frequency is 2450 megahertzs；
(5) namely mix obtains the component A finished product of sludge dewatering conditioner after the fine powder that step (4) is prepared is extremely uniform.
(2) B component
Weigh by the mass component of PDDA (PDADMAC), and in water: the ratio of B=49:1 is dissolved standby；
(3) component A and B component solution composition sludge dewatering conditioner.
The purposes of described sludge dewatering conditioner, it is characterised in that: during use, every 100kg mud adds 2～5kg sludge dewatering conditioner, after first adding component A, add B component, successively add component A, B component interval is 1～2 minute, then uses filter press dehydration.
The structural behaviour of mud mud containing a large amount of moisture content, water reason characteristic, physical and mechanical property can be carried out inherent conditioning by the sludge dewatering conditioner of the present invention, build the endogenous environmental condition of one contributing to mud slurry dewatering.Mud high speed dewatering of slurries is allowed when in fact currently using plant equipment.The preparation method that the present invention also provides for this kind of sludge dewatering conditioner: be that metal-oxide and nonmetal oxide are carried out high-temperature roasting and microwave radiation, make it have required activity, then by the component determined and the mass component preparation determined, and levigate to required fineness, with the use of diallyl ammonium chloride solution.
