Abstract
The invention relates to a method and a device for quickly improving the black-odorous large and medium rivers. Nitrate and denitrifying bacteria are added into the water body, wherein the addition amount is as follows: 5-6g of nitrate is added into 1g of COD in the water body, and 2-3Kg of solid-state denitrifying bacteria is added to each mu of water surface; the pH value of the water body is adjusted to 5-6 at the same time. The method and device provided by the invention can quickly improve the black-odorous phenomenon of the water body and have the advantages of investment saving, quick effect, good effect, easiness in operation and the like.
Description
Technical field
The invention belongs to sewage purification technology field, relate in more detail the black smelly method and apparatus in the big-and-middle-sized river of a kind of quick improvement.
Background technology
Black smelly be a kind of extreme phenomenon of organic contamination, be due to water hypoxia, organism is corrupt to be caused, and causes the anaerobic digestion that the black smelly major cause of water body is organic substance in water body.When a large amount of organic pollutants enters water body, under the biochemical action of aerobic microbiological, consumed oxygen a large amount of in water body, anaerobic bacterium amount reproduction, make organism corrupt, decompose, fermentation, be decomposed into ammonia nitrogen, soil ulmin, hydrogen sulfide, methane and mercaptan etc.This process causes that oxygen consumption is greater than reoxygenation, cause anaerobic environment, the odour effusion water surface that has producing enters atmosphere, the heavy metal such as iron, manganese reduction in water, with the sulphur reduction-state in water, the sulfide suspended particle that comprises FeS and MnS that has formed a large amount of electronegative colloids, makes water body blackening, fouling.Therefore the key of improving black smelly river course is to improve the redox state of water body, aeration aerating is to improve the black smelly modal technique means of water body, but the aeration aerating cycle is slower, effect is poor, easily bed mud is stirred, operational conditions is difficult to control, in some remote districts because power supply system imperfection is also difficult to realize aeration aerating.
Summary of the invention
The object of the present invention is to provide the black smelly method and apparatus in the big-and-middle-sized river of a kind of quick improvement, to improve the defect existing in known technology.
For achieving the above object, the black smelly method in the big-and-middle-sized river of quick improvement provided by the invention, to water body, add nitrate radical and denitrifying bacteria, dosage is: in water body, 1g COD adds 5-6g nitrate radical, every mu of water surface adds the solid-state denitrifying bacteria of 2-3Kg, hundred million/g of denitrifying bacteria concentration 30-100 is adjusted into 5-6 by water pH value simultaneously.
In described method, the nitrate radical place of adding is that the denitrifying bacteria place of adding is in the scope apart from this section 1Km apart from this 2Km place, section upstream.
In described method, nitrate radical is nitrocalcite or SODIUMNITRATE.
In described method, hang soft biological membrane carrier to guarantee the reproduction speed of nitrifier in water body, biofilm carrier is protruded packing, and specific surface area is greater than 2000.
In described method, denitrifying bacteria is one or both in denitrification bacillus, Si Shi bacillus.
The present invention, for adding the device of nitrate radical and denitrifying bacteria, comprising:
One GPS station keeping ship, is provided with volume pump and robot control system(RCS) on ship, according to the COD densitometer of different zones, calculate medicine dosage, and the coordinate of different zones and medicine dosage are input to and in robot control system(RCS), control volume pump and offer medicine.
In described device, robot control system(RCS) is a computer.
The present invention adopts and adds nitrate radical in the presence of denitrifying bacterium, consume rapidly in a short time the organism of water body, due to the breeding of denitrifying bacterium, can form competition mechanism with sulfuration bacterium simultaneously, suppress the growth of sulfuration bacterium, and then suppress the generation of hydrogen sulfide.Therefore one aspect of the present invention can be improved water body redox potential, to cause MnS and the FeS oxidation of water body blackout, and then eliminate water body black, reduce the concentration of the COD of water body aerobic substance simultaneously, can also suppress the generation of hydrogen sulfide, the multi-pronged black smelly phenomenon of water body of improving.
Embodiment
The present invention is directed to typical black and odorous water, proposed a set of instant effect, effective, the device of easy-operating method.
Device provided by the invention mainly adopts GPS station keeping ship, and ship is provided with volume pump, quantitatively offers medicine and robot control system(RCS), according to the COD concentration of different zones, calculate medicine dosage, the coordinate of different zones and medicine dosage are input to computer program, concrete medication administration method is as follows:
First water body adds nitrocalcite or SODIUMNITRATE, dosage calculates according to water quality monitoring (WQM) result, in order to guarantee that the black smelly phenomenon of water body of river section occurs, need to add nitrate radical apart from this 2Km place, section upstream, in the scope of this section 1Km, evenly add denitrifying bacteria, in water body, 1g COD adds and need add 5-6g nitrocalcite, water pH value is adjusted into 6 simultaneously, every mu of water surface 2-3Kg of denitrifying bacterium, for guaranteeing the reproduction speed of denitrifying bacterium, water body the inside hangs soft biological membrane carrier, and biofilm carrier is protruded packing, and specific surface area need be greater than 2000.
Add nitrocalcite, and regulate water body pH can improve in a short time the redox potential of water body, will cause that black smelly ferrous ion and mn ion are oxidized to ferric iron or value Mn, and then eliminate the black of water body.Introduce denitrifying bacterium simultaneously.The nitrate radical adding, in the presence of denitrifying bacterium, consumes rapidly the organism of water body in a short time, due to the breeding of denitrifying bacterium, can form competition mechanism with sulfuration bacterium simultaneously, suppresses the growth of sulfuration bacterium, and then suppresses the generation of hydrogen sulfide.Therefore present method can be improved water body redox potential on the one hand, reduces the concentration of the COD of water body aerobic substance simultaneously, can also suppress the generation of hydrogen sulfide, improves the black smelly phenomenon of water body.Denitrifying bacteria of the present invention can be one or both in denitrification bacillus, Si Shi bacillus.
Embodiment:
Certain black and odorous water, water surface area is 200 mu, the water yield approximately 50,000 m
3/ d, the starting point concentration of COD is 200mg/L, to water body, adds approximately 500,000 m
3/ d * 200mg/L * 5=500t nitrocalcite, adds 200 mu * 3kg denitrifying bacteria=600kg denitrification bacillus and Si Shi bacillus to water body simultaneously, and before and after processing, water quality changes specifically as shown in table 1:
