Description
Technical field
The invention belongs to the environmental improvement technical field, be specifically related to the method that a kind of bed mud aeration is repaired city heavily contaminated water body.
Background technology
Urban water-body is meant river course in the city, inland lake, park water etc., and its characteristic feature is the influence that water quality is subject to urban life, production and social activity, especially receives directly influencing of municipal drainage and precipitation runoff.The heavily contaminated water body is meant that pollutant loads such as organism, ammonia nitrogen, phosphorus are higher in water body and the bed mud, and water transparency is lower, and smelly or algal bloom is deceived in regular generation.
Usually, for the water body restorative procedure, mainly contain two big types: the one, the water quality reparation.Restorative procedure comprises and changes water, aeration oxidation, adds engineering bacteria etc. that perhaps several kinds of restorative procedures is used in combination.Changing water its mechanism in the water body restorative procedure is exactly " dilution ", utilize water quality preferably other source water dilute the heavily contaminated water body, reduce its Pollutant levels, change apparent pollution, but this method only takes stopgap measures, but not effects a permanent cure.Aeration aerating is a kind of method that the water body reparation is extensively adopted, and this method can be improved the black smelly degree of water body, but general to organism in the water body, ammonia nitrogen, phosphorus removal effect, and in case stop aeration, water quality can worsen rapidly.In above-mentioned several kinds of restorative procedures, can add engineering bacteria and strengthen the water quality repairing effect, but can introduce new ecological risk like this.The 2nd, the bed mud reparation.Restorative procedure comprises that bed mud desilting, bed mud cover etc.The bed mud desilting is meant through removing the water body bed mud and reaches the purpose that reduces endogenous release, but this method is still under test.Although be applied at some water body, the water correction effect does not reach expection fully, and bed mud is easy to cause secondary pollution after the desilting, drops into bigger simultaneously.Bed mud is covered and is meant the redox potential that adds chemical agent change bed mud-water termination, or adopts materials such as sand, flyash to cover bed mud, suppresses endogenous release.
If the water quality reparation is combined with the bed mud reparation, the water body repairing effect is much better than simple water quality reparation or bed mud reparation.This class methods majority is to be main with the bed mud desilting, also has simultaneously to adopt to add chemical agent.But these class methods have than obvious defects: otherwise fund input is big, and also the bed mud of desilting is mishandling, produces secondary pollution, or introduces new chemical risk.
Based on above reason, invent the restorative procedure of the high bed mud of a kind of effectiveness, the mishandling introducing secondary pollution problems of, bed mud big with the amount of investment that solves traditional restorative procedure has become the technical problem that needs to be resolved hurrily in the art.
Summary of the invention
For overcoming deficiency of the prior art; The objective of the invention is to propose a kind of bed mud aeration and repair the method for city heavily contaminated water body, solved the resource input that city heavily contaminated water body restorative procedure causes in the prior art big, introduce secondary pollution, water body reclamation activities to water body and stop back water quality problem such as deterioration rapidly.
For solving the problems of the technologies described above, reach above-mentioned technical purpose, the present invention adopts following technical scheme:
A kind of method of utilizing the bed mud aeration to repair city heavily contaminated water body may further comprise the steps:
(1) bed mud aerating step: with aerating apparatus the water body bed mud is carried out aeration, impel bed mud to suspend, utilize the suspension bed mud that pollutents such as organism, ammonia nitrogen, phosphorus in the water body are adsorbed, and pass through oxidation removal; Also can produce oxygenizement simultaneously, avoid water body black smelly producing black smelly material such as sulfide etc.
(2) bed mud precipitation step: adopt settling process to carry out sedimentation to the bed mud that suspends.
Preferably, the aerating apparatus in the said step (1) is for moving the tubulose microporous aeration device; The aeration rate of aerating apparatus is 5L/m
2Min～25L/m
2Min; Bubble size is between 1.5mm～3mm; Aeration time is 10min～6h every day.
Preferably, the settling process in the said step (2) is natural sedimentation or flocculation sedimentation.After natural sedimentation was meant that aeration stops, the bed mud natural subsidence of suspension did not add any flocculation medicament.Flocculation sedimentation is meant 30min before aeration finishes, and adds flocculation agent (1-2mg/L is in aluminium).Flocculation sedimentation is only selected for use at the higher landscape water body of people's attention rate.
Reaction mechanism of the present invention: in the technical scheme of the present invention; Impel bed mud to suspend through the bed mud aeration; Increase inorganic particle material content in the overlying water; Strengthen the contact probability of pollutents such as organism, ammonia nitrogen, phosphorus in inorganic particle material and the water body, the bed mud that impels pollutent to be suspended is caught, absorption, fixing.Simultaneously, in aeration process, recover the activity and the quantity of aerobic microbiological in the bed mud, accelerate degraded pollutent in water body and the bed mud.For the organism that can not degrade and be oxidized to nitrate salt nitrogen, be converted to the difficult phosphorus that discharges attitude etc., then can be adsorbed, and in settling process, realize by the migration of water to bed mud by bed mud.Thereby accomplish purpose to water quality and bed mud double purified.Because the bed mud oxygenizement can be avoided owing to bioturbation, temperature Change produce black smelly that " turning over the pool " causes.
Concrete, the bed mud aeration is repaired city heavily contaminated water body and is mainly comprised two aspects, the one, water quality reparation, the 2nd, bed mud reparation.These two aspects are actually simultaneous, impel bed mud to suspend through the bed mud aeration and accomplish.Bed mud aeration process, the tubulose microporous aeration device that promptly passes through to move impel bed mud to suspend to the bed mud aeration; Accelerate inorganic, the diffusion of organic granular material in water body in the bed mud; The inorganic particle material because of it has bigger specific surface area can be to absorption such as the organism in the water body, ammonia nitrogen, phosphorus, and the metals ions such as ferrimanganic in the bed mud can be oxidized, changes into oxidation state; Cause endogenous phosphorus in the bed mud to take place to discharge the conversion that attitude is changeed to difficulty, help phosphorus fixation by being prone to discharge attitude.Organic granular material in the bed mud reduces water body organic contamination degree then by mineralising, recovers the water body dissolved oxygen concentration, reduces black smelly occurrence frequency.The activity of aerobic microbiological is resumed in aeration process in the bed mud, helps the oxidation removal to pollutents such as organism, ammonia nitrogens.The bed mud settling process promptly stops aeration, gets into the quiescent setting stage, and the bed mud of suspension is in the action of gravity settle, and the pollutent that is adsorbed simultaneously precipitates in the lump, thereby water quality is purified.In precipitation process, water-bed original anaerobism or aerobic-anaerobic microbe can continue the pollutent in the bed mud is degraded.Through repetitious aeration disturbance, deposition, continue water quality and bed mud are purified.Bed mud has formed the granularity of suspended matter in the water body and the sorting of proportion through repetitious suspension, and the sedimentation effect of suspension bed mud is strengthened.Therefore, behind bed mud aeration after a while, the settling velocity of suspension bed mud can be accelerated, and progressively recovers the water landscape function.Flocculation sedimentation only is to select for use at the bed mud aeration reparation initial stage.
In the technique scheme, said water pollution is serious, and water body is in unhurried current or viscous flow state, and organic content (permanganate index) is more than 8mg/L, more than the ammonia nitrogen 10mg/L, more than the soluble phosphate 0.2mg/L.Water body bed mud (is main with the alluvial bed mud) thickness is more than 10cm.The bed mud aeration time is 5h～6h every day.
Compare with scheme of the prior art, advantage of the present invention is:
1. bed mud aeration of the present invention is repaired city heavily contaminated water body method, compares with restorative procedure in the past, when water quality is repaired, bed mud is purified, and avoids introducing new chemistry, biological risk to water body, does not destroy the original ecotope of water body; Reduce resource consumption; Reduce bed mud desilting frequency, correspondingly reduced bed mud subsequent processes expense.
2. the present invention proposes the technical measures that water quality and bed mud are repaired simultaneously, for the urban water-body reparation provides new technological line.
3. the present invention is suitable for controlling city unhurried current water body or the impounded body that external source is polluted, and is not influencing or is destroying under the situation of water landscape function and water ecological setting, realizes the water body reparation.
