Abstract
The invention discloses an artificial wetland for treating lime-rich alkali waste water and a treatment method thereof, wherein a water inlet of one end of an artificial wetland tank body is connected with a sedimentation tank through a water pipe, and a water outlet of the other end of the artificial wetland tank body is connected with a clear water reservior through a drain pipe; a composite filler which is prepared from 15 percent-60 percent of soil and 40 percent-85 percent of compost according to the volume percent is filled in the artificial wetland tank body, and alkali-resistant wetland plants are planted on the composite filler; the lime-rich alkali waste water is preliminarily precipitated in the sedimentation tank; the alkali waste water after the preliminary sedimentation is discharged into the artificial wetland tank body through a water pipe; the alkali waste water stays in the artificial wetland tank body for at least 12h; and the purified water is discharged into the clear water reservoir through the discharge pipe. With the invention, the pH value of the waste water, suspended particle concentration and calcium content can be effectively reduced, and the invention can be used for treating the waste water of the building construction process, fire coal desulfuration solid waste percolate, the dedusting waste water of a revolving furnace of a steel work and other lime-rich alkali waste waters.
Description
Technical field
The present invention relates to a kind of artificial swamp that is used for wastewater treatment, and the method for wastewater treatment that adopts this artificial swamp.
Background technology
The alkaline waste water source of being rich in lime is very extensive, and for example the annual building waste that produces of China reaches ten thousand tons of 4000-5000, and stack or simple and easy landfill in the unprocessed suburb that directly transports to of the overwhelming majority, and building waste percolate pH can reach 11.System alkali, iron and steel manufacturing also produce the solid waste that is rich in lime in a large number in the processes such as coal desulfurization, these solid waste produce alkaline percolate through weathering, rain drop erosion.In addition, cement, concrete production, and also can produce the alkaline waste water that contains lime and lime carbonate in a large number in the building construction process.
If these alkaline waste waters directly discharge the entering water body then can influence hydrobiont metabolism, cause the Digestive tract imbalance, hydrobiont there is direct toxic action.Often contain large quantities of lime in the strong basicity waste water, accumulating deposition and can influencing photosynthesis of plant of lime carbonate destroys the living space of zoobenthos.Therefore, alkaline waste water must suitably be handled, waste water ph is reduced after, can be discharged into receiving water body.
The existing method of handling alkaline waste water mainly contains neutralisation, chemical precipitation method, aeration etc.; To for alkaline waste waters such as the trade effluent of a large amount of dischargings, percolates; Existing treatment process need be equipped with a large amount of physics, chemical reaction equipment and reaction reagent; Not only processing cost height, complex process, equipment maintenance difficulty are big, also can produce certain destruction to environment.
Constructed wetland waste water treatment technology is to utilize ecological method to remove pollutent, to reach the purpose of purifying waste water, has that processing unit is simple, operation maintenance management convenient, characteristic of low energy consumption.But existing manual wetland sewage disposal technology is used for handling sewage more, and removes the heavy metal ion in the trade effluent, and is not suitable for the alkaline waste water that lime is rich in processing.
Summary of the invention
The present invention provides a kind of artificial swamp and treatment process thereof that is rich in the lime alkaline waste water that be used to handle, and solve the alkaline waste water that is rich in lime and be difficult to the Treatment Technology problem, and the existing artificial swamp of solution is not suitable for alkaline waste water Treatment Technology problem.
The technical solution adopted for the present invention to solve the technical problems is:
Thisly be used to handle the artificial swamp that is rich in the lime alkaline waste water; Comprise artificial swamp pond body, body inside, said artificial swamp pond is filled with compounded mix, and kind is implanted with the alkali resistance wetland plant on compounded mix; One end top of artificial swamp pond body is provided with water-in; Water-in is connected with settling tank by water pipe, and the other end bottom of artificial swamp pond body is provided with water outlet, and water outlet is connected with water purifying tank by water shoot.
The filling degree of depth of said compounded mix is 30～50cm.
The treatment process that is rich in the lime alkaline waste water of this employing artificial swamp, treatment step is following:
Said alkali resistance wetland plant be in reed, Scirpus tabernaemontani or the cattail a kind of, two or three.
Useless admittedly percolate of the waste water that the said alkaline waste water that is rich in lime is a building construction process, coal desulfurization or steelwork converter dust waste water.
Beneficial effect of the present invention is following:
The present invention fills by soil and the formulated especially compounded mix of compost body inside in the artificial swamp pond.Wherein compost is to utilize various plant residues, is main raw material like straw, weeds, peat, rubbish, mixes people's domestic animals manure, through multiple action of microorganisms, and the organic fertilizer that the composting decomposition forms.The present invention can improve the physicochemical property of soil with compost and mixing with soil preparation, increases soil fertility, and helps the growth of plant.Soil and compost have very strong surge capability to acid-basicity, and alkaline waste water pH value is significantly reduced.Microorganism active is strong in the compost, can produce a large amount of CO
2Thereby, effectively remove Ca in the waste water
2+
Plantation alkali resistance wetland plant in the body of artificial swamp of the present invention pond is like reed, Scirpus tabernaemontani or cattail.This type of plant-growth is comparatively extensive, and alkali resistance is strong.Alkaline-resisting root system of plant and filler have filtering function, make wetland have the good suspension PM for particulate matter and remove ability.
The present invention is especially to lime alkaline waste water design, have treatment effect good, simple in structure, cheap, need not power, need not constantly to add the advantage of flocculation agent.Can intermittent water inflow, the characteristics of intermittent drainage in the artificial swamp with meeting factory and construction.The water purifying tank water outlet can recycle, economic environmental protection.In addition, the construction of wetland can also beautify the environment, reduce noise, increase atmospheric moisture.
The present invention can make waste water ph, suspended particulate matter concentration and calcareous content effectively reduced, and can be used in the processing that the useless admittedly percolate of waste water, coal desulfurization, steelwork converter dust waste water etc. of building construction process are rich in the alkaline industrial waste water of lime.
