Abstract
This invention provides an environmentally friendly composite water-treatment agent, which is prepred from Phargmites communis, Eichhornia crassipes, Opuntia ficusindica, Nelumbo nucifera, zeolite, sepiolite and diatomite. The preparation method and the composition are decided according to the characteristics of wastewater. Compared with the present water-treatment agents, the composite water-treatment agent in this invention is economic, efficient and environmentally friendly, and has such advantages as wide applications and no secondary pollution. The water-treatment agent can be used to treat industrial wastewater, domestic wastewater, agricultural subsiding water, domestic water sources and city water-supply systems.
Description
Technical field
The invention belongs to water-treatment technology field, relate in particular to a kind of ecological, environmental protective composite water treatment agent.
Background technology
Along with the Chinese society rapid development of economy, the discharging of large amount of sewage not only makes the consumption of water conditioner sharply increase, and to the demands for higher performance of water conditioner.With regard to the integral production application feature of present China water conditioner, part also comes with some shortcomings, mainly show: existing inorganic water conditioner exists function singleness at present, suitable water body is limited in scope, and usage quantity is big, the flco amount is bigger, sedimentation speed is slow, sludge dewatering is difficult and the final processing cost of mud is higher, especially remains in the aluminum ion in the water body, and plant, aquatic organism and human body have all been constituted potential harm; Organic synthesis polymer water conditioner, as polyacrylamide etc., not only production cost is higher, and it is bigger to human health damage in the production building-up process, use the most of polymer in back to be difficult to again by environment degradable, a large amount of accumulation and long-term existence produce secondary pollution to environment in physical environment, though the small portion polymer can be degraded to small molecules such as acrylamide monomer, its toxicity and carinogenicity are all very strong.We can say, existing inorganic water conditioner and organic synthetic polymer water conditioner, producing or in use, the ecological insecurity that is showed and to the secondary pollution problem that environment caused has more and more caused people's extensive concern and worry.Therefore, develop ecological safety environment-friendly composite water conditioner energetically and become a kind of common recognition.How on a higher aspect, environment effectively to be protected; how to make water conditioner by low molecule to polymer; to compound, from the secondary pollution to the safety and environmental protection, become a crucial research topic in the engineering of water treatment field from single type.
Summary of the invention
The object of the present invention is to provide a kind of economy, efficient, ecological security is high, applied widely, non-secondary pollution, environment amenable water conditioner specifically provides a kind of ecological, environmental protective composite water treatment agent.
A kind of ecological, environmental protective composite water treatment agent provided by the invention is to be prepared from by reed, water hyacinth, Root and stem of Cholla, lotus leaf, zeolite, sepiolite and diatomite, and its preparation method and component are:
(1) when being used to dispose of sewage, prepare with method according to the following steps: 1. by the quality per distribution ratio, after reed with 25～45%, 5～10% water hyacinths, 25～35% Root and stem of Cholla and 15～25% lotus leaves are smashed stirring, soaked 10～15 days with deionized water, soak solution is concentrated, and its concentration is 20～35%; 2. by the quality per distribution ratio, 45～55% zeolites, 15～25% sepiolites and 20～35% diatomite are mixed, under the condition of 150～350 ℃ of temperature, be ground to 350～450 orders, and stir; 3. by the quality per distribution ratio, 35～45% concentrated solutions that make for 1. method and join in the high speed kneader by 50～65% the powder that 2. method makes, be heated to 50～90 ℃ and stirred 25～30 minutes, promptly make the ecological, environmental protective composite water treatment agent that is used to dispose of sewage.
(2) when being used for the processing of rivers source water, prepare with method according to the following steps: 1. by the quality per distribution ratio, after reed with 30～45%, 10～15% water hyacinths, 15～25% Root and stem of Cholla and 20～30% lotus leaves are smashed stirring, soaked 10～15 days with deionized water, soak solution is concentrated, and its concentration is 20～35%; 2. by the quality per distribution ratio, 25～35% zeolites, 25～35% sepiolites and 25～40% diatomite are mixed, be ground to 350～450 orders under the condition when 150～350 ℃ of temperature, and stir; 3. by the quality per distribution ratio, 65～75% the concentrated solution that makes for 1. method and join in the high speed kneader by 25～35% powder of 2. method steps preparation, stirred 25～30 minutes when being heated to 50～90 ℃, promptly make the ecological, environmental protective composite water treatment agent that is used for the source water processing.
(3) when being used for sewage disposal, the water conditioner add-on is 0.3%～0.75% of a sewage quality, fully mixes after the input.
(4) when being used for the source water processing, the water conditioner add-on is 0.15%～0.6% of a water body quality, fully mixes after the input.
This water conditioner principle of work is such: when ecological composite environmental-friendly water conditioner joins in the sewage, under high-speed stirring, be diffused in the water body rapidly, at this moment, in the uneven current potential on water conditioner surface and the charge potential of suspended ion, its current potential that repels each other is weakened, because bonding, net is caught, volume such as sweeps at effect, and make colloidalmaterial, suspended solids is spent with being partly dissolved material and water conditioner formation floc sedimentation or being condensed into bigger wadding, because the huge surface-area of water conditioner, nanometer micropore volume and very strong adsorptive power are with the fine material in the sewage, virus etc. are adsorbed onto surface and hole inside.Meanwhile, water conditioner can discharge has the allelochemical that suppresses or kill the algae effect, and this allelochemical can be killed the algae in the sewage on the one hand, can suppress algae grows on the other hand.Floc sedimentation particle precipitation rapidly under action of gravity subsequently, and separate with cleaning water body after handling.Thereby the turbidity, colourity, organism, inorganics and the algae that make water body obtain removing.
This water conditioner is compared with water conditioner commonly used both at home and abroad at present has following beneficial effect:
(1) preparation process of the present invention is simple, need not complex apparatus and adds any chemical substance, and with short production cycle, simple to operate, production cost is low
(2) water conditioner of the present invention's preparation, flocculating property is good, and adsorptivity is strong, and consumption is few, and flocculation rate is fast, and the alumen ustum size is big, and settling of floccus speed is fast, and settling time is short.
(3) water conditioner of the present invention's preparation not only can be used for the water treatment of industrial sewage, sanitary sewage and agriculture water-break, but also can be used for water treatment and town water supply water treatment to the life water source water body.
(4) water conditioner of the present invention preparation, the repeated regeneration that not only can circulate for a long time uses, but also has harmlessly, nontoxic, pollution-free, does not produce derivative, has the characteristics of significant safety and environmental protection.
(5) water conditioner of the present invention's preparation not only the organism in the sewage, nitrogen phosphorus and heavy metal are all had significant removal effect, and to virus, mushroom and algae has killing or suppresses the growth effect.
