Abstract

The invention discloses a bypass purification method for heavy polluted rivers. The bypass purification method mainly comprises the following steps: connecting a diversion stirring device of an A/O sewage treatment plant with a heavy polluted river channel, constructing a constructed wetland 10 meters away at the downstream of the river channel along the bank, and introducing a polluted water body inside the river channel into the constructed wetland by using a submersible pump. The invention further discloses a method of the bypass purification method for heavy polluted rivers. The bypass purification method is particularly remarkable in treatment effect on situations such as high content of organisms and nutrient salts and black and odorous water.

Description

The bypass purification method in a kind of heavily contaminated river and method
Technical field
The present invention relates to the bypass purification method in a kind of heavily contaminated river.
The method that the invention still further relates to utilize said apparatus to carry out the process of heavily contaminated river.
Background technology
China's major part city river has developed into black-odor riverway at present.In China's many cities, river course Pollute and generally exist and become increasingly conspicuous, the in line river course of municipal sewage, flow through section, cities and towns seriously polluted, Water body occurs seasonal or the most black smelly, all becomes in China's current city river pollution problem and urgently solves Water environmental problems certainly.
So-called black smelly be due in water body containing a large amount of hydrogen sulfide (H2S), black smelly state is water body One extremity, the feature of itself is also very different with other states, and water body has abnormal flavour, Through be not suitable for aquatile existence, aquatic vegetation degenerate even become extinct, phytoplankton, zooplankton, Zoobenthos only has a small amount of resistant kind to exist.Food chain ruptures, and food web is incoherent, ecosystem Structure serious unbalance, function serious degradation is even lost.The invention discloses a kind of heavily contaminated river The method of bypass purification method, for river course Organic substance, nutrient concentrations height and the black smelly feelings of water quality Condition treatment effect is particularly evident.
Summary of the invention
It is an object of the invention to provide the bypass purification method in a kind of heavily contaminated river.
The method that a further object of the present invention is to provide the bypass purification method in a kind of heavily contaminated river.
For achieving the above object, the bypass purification method in the heavily contaminated river that the present invention provides, mainly wrap Include:
A/O sewage treatment plant connects heavily contaminated river course by diversion agitating device, flows to downstream along river course Build an artificial swamp at 10 meters of embankments, here by immersible pump, polluted water body in river course is introduced people Work wetland purification;
Wherein: the anaerobic pond that A/O processes pond transform limited aeration pond as, by automatically controlling, makes The dissolved oxygen concentration of original anaerobic pond keeps < 2mg/L, the Denitrification in minimizing amphimicrobian pond, guarantor Containing substantial amounts of nitrate anion in water outlet in card A/O sewage treatment plant, use micro-aeration can also make sewage The humic acid in organic moiety in treatment plant's water outlet is not removed, and substantial amounts of humic acid can be anti- The growth of nitrobacteria provides the condition of Fast-propagation.Cancel the sterilization process of sewage treatment plant simultaneously, Ensure that sewage farm has substantial amounts of function purifying water micrcxDrganism not to be inactivated.By A/O sewage treatment plant Secondary effluent introduce heavily contaminated river course by diversion agitating device, and flowing water in river course and A/O is dirty Water treatment plant's secondary effluent uniformly mixes (ensureing that COD is less than 200mg/L), adds to river course simultaneously Denitrifying microorganism, the denitrification process in strengthening black-odor riverway, in water body, substantial amounts of humic acid is permissible Stimulating the fast-growth of denitrifying bacteria, on the one hand the breeding of denitrifying bacteria can suppress to vulcanize bacterium life Long, denitrifying bacteria can also consume substantial amounts of Organic substance in upper river water after preponderating.
Artificial swamp is built in 10 meters of river course at a distance, and is introduced by flowing water in river course in artificial swamp, logical Cross artificial swamp and remove Organic substance more than needed in river and N, P nutritive salt;
Wherein, the A/O secondary effluent from sewage treatment plant water yield and streamflow in river course are less than or equal to 1:1; The moisturizing water yield in sewage treatment plant is difficult to excessive, and excessive meeting changes the physicochemical environment in original river course, Causing the secondary ecocatas-trophes such as blue-green alga bloom, additionally in sewage treatment plant's water-break, substantial amounts of pathogen also may be used River course can be caused risk.
Wherein, streamflow 50% in artificial wetland treatment amount is river course;In artificial wetland treatment river course The water yield is difficult to excessive, and on the one hand artificial swamp can purify water, and eliminates the pathogen of black-odor riverway, On the one hand it is also possible to the seed of the protozoacide in river, plankton, and water plant Filtered out, and the seed of protozoacide, plankton and water plant is extensive to the ecology in river course Multiple most important, if they filtered out, the ecology of later stage black-odor riverway will be difficult to recover.Wherein, In river course, the amount of microbe inoculation is 10mg, and every mu of water surface adds 4-5Kg solid-state denitrifying bacterium, anti-nitre Change hundred million/g of bacteria concentration 50-100, inoculate the most on startup once.
Wherein, the hydraulic detention time of artificial swamp water inlet is 10d, and hydraulic load is 15cm/d, Fe3+ Content is less than 0.5mg/L, and under above-mentioned design parameter, artificial swamp is possible not only to purify black-odor riverway With the COD in the mixing water of sewage treatment plant, NH3-N etc. cause black smelly major pollutants, also may be used To be removed by the pathogen such as the escherichia coli in water body, reduce the risk of water body.
By combinations of the above technique, make full use of sewage disposal and purify black with the group technology of microorganism The water quality in road, both can eliminate the black smelly phenomenon of water body, and the restoration of the ecosystem for the later stage lays the foundation again.

Detailed description of the invention
Elaborate below in conjunction with accompanying drawing.It should be noted that the left side mentioned in the following description, Right, upper and lower etc. is all to be as the criterion with direction shown in the drawings.
Refer to Fig. 1.The bypass purification method in the heavily contaminated river that the present invention provides, its primary structure Including:
A/O sewage treatment plant (1) secondary effluent enters river course, by drawing by immersible pump (3a) Water agitating device (4) uniformly mixes with heavily contaminated river course river;(ensureing that COD is more than 200mg/L), Add denitrifying microorganism suppression sulfuration bacteria growing simultaneously;
Flow to along river course build an artificial swamp (6), here by immersible pump at the embankment of 10 meters of downstream (3b) after polluted water body in river course being introduced artificial swamp (6) purification, by immersible pump (3c) Discharge;(COD be less than 20mg/L), by artificial swamp remove Organic substance more than needed in flowing water with And N, P nutritive salt.
