Description
Technical field
The present invention relates to the sewage purification process field, specifically is the precipitation technology that is applied to combined artificial wetland sewage purification pretreatment stage, especially a kind of be applied to the pretreated ecological precipitation agent of combined artificial wetland sewage purification and its production and application method.
Background technology
Along with the Chinese society rapid development of economy; Quantity of wastewater effluent increases year by year; Under the development of several years novel ecological technology, the artificial swamp method is disposed of sewage and is more and more received people's favor, stops up because of carrying excessive suspended substance (SS) or impurity in the sewage in order to prevent artificial wet land system; Need carry out pre-treatment; The precipitation agent effect quality of pretreatment stage plays an important role for the steady running of system, and artificial wet land treating system requires the processing links of its upstream and downstream all to have the environmental treatment technology that matches as a kind of ecological environment-friendly type sewage disposal technology.And with regard to the production application feature of China's precipitation agent; Also be difficult to find the product that is complementary; Mainly show: existing electrodeless precipitation agent exists function singleness at present, and suitable water body is limited in scope, and usage quantity is big, the flco amount is big, sedimentation speed is slow, sludge dewatering is difficult and ready-made of mud place is high; Especially remain in the aluminum ion in the water body, can cause unnecessary pollution; Organic synthesis polymer precipitation agent; Not only production cost is high; And bigger to human health damage in the production building-up process, use the back difficult degradation, a large amount of accumulation and long-term existence in physical environment; Environment is produced secondary pollution, and its toxicity of the material that small portion is degraded and carinogenicity are all very strong.Existing precipitation agent is difficult to satisfy the deposition needs of artificial swamp sewage purification pretreatment stage.
Summary of the invention
The technical problem that the present invention will solve provide a kind of economy, efficient, ecological security is high, non-secondary pollution, environment amenable ecological precipitation agent.
The present invention also provides the preparation method of above-mentioned ecological precipitation agent.
The present invention further provides the application method of above-mentioned ecological precipitation agent.
For solving the problems of the technologies described above; The technical scheme that the present invention taked is: a kind of ecological precipitation agent; Be used for combined artificial wetland sewage purification pre-treatment; It is that 1: 1.4～2 component A and B component are formed by ratio of weight and number, and said A component contains 40-50wt% reed, 30-40wt% Herba Eichhorniae and 15-25wt% lotus leaf, and said B component is that 1: 2: 3 zeyssatite, vermiculite, activated carbon formed by ratio of weight and number.
The preparation method of above-mentioned ecological precipitation agent provided by the invention is: prepare component A and B component respectively; The preparation method of component A is for to smash stirring with 40-50wt% reed, 30-40wt% Herba Eichhorniae and 15-25wt% lotus leaf; Soaked 10-15 days with deionized water; Soak solution is concentrated, concentration is 30wt% again;
The preparation method of B component is for taking by weighing zeyssatite and vermiculite in 1: 2 by ratio of weight and the number of copies; Mix; Under 150-350 ℃ of temperature, be ground to 350～450 orders, and then the equal rank particulate of quality gac such as sneak into, at last three's mixture is put into stirrer and evenly stir and form powder;
Obtained component A and B component 1: 1.4 by ratio of weight and the number of copies～2 are joined in the high speed kneader, be heated to 50-90 ℃, stirred 20-30 minute.
The application method of above-mentioned ecological precipitation agent provided by the invention is: when being used for sewage pre-treatment deposition, ecological precipitation agent add-on is 0.2～0.65% of a sewage weight, mixes fully after the input, sewage water filtration is drawn to get final product then.
This ecological precipitation agent principle of work is: after the ecological precipitation agent that is applied to combined artificial wetland sewage purification processing joins in the sewage; Under high-speed stirring, be diffused in the water body rapidly; This moment ecological precipitation agent surface uneven current potential in the charge potential of suspended ion; Its current potential that repels each other is weakened,, form floc sedimentation or be condensed into bigger wadding with precipitation agent and spend and make colloidalmaterial, suspended solids and part be partly dissolved material because bonding, net catches, roll up effect such as sweep; Because the surface-area that ecological precipitation agent is huge, the extremely strong adsorptive power of nanometer micropore volume, it is inner that the fine material in the sewage, virus etc. are adsorbed onto the surface-area space.Simultaneously, ecological precipitation agent 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.The floc sedimentation particle precipitates rapidly under action of gravity subsequently, and separates with the clean water body after handling, thereby makes turbidity, colourity, organism, inorganics and the algae of water body obtain the deposition removal.
Adopt the beneficial effect that technique scheme produced to be: 1, this ecological precipitation agent flocculence is good, and adsorptivity is strong, and consumption is few, and flocculation gathers that speed is fast, and the alumen ustum size is big, and settling of floccus speed is fast, and settling time is short; It not only has significant removal effect to the suspended substance in the sewage, impurity, and to virus, and mushroom and algae are also killed or suppress the growth effect; It is nontoxic, harmless, pollution-free, does not produce verivate, safety and environmental protection.
2, preparation process of the present invention is simple, need not complex apparatus and any chemical substance, and with short production cycle, cost is low.
3, the present invention is applied to artificial compound wet land sewage purification pre-treatment, can greatly reduce the processing pressure of sewage in the subsequent processes.
