Abstract
A process for treating sewage by microbes includes early-stage dynamic culture of composite microbes for 7-15 days, dynamic culture for 8-10 days, and dynamic running (continuously treating sewage). Its advantages are high effect, no poison, harm and secondary pollution.
Description
Technical field
The present invention relates to a kind of sewage water treatment method, particularly relate to a kind of microbial treatment process sewage of utilizing.
Background technology
Current, China's municipal sewage treatment technology mainly adopts the conventional activated sludge method, belongs to the suspension growth system, need introduce a large amount of active sludge provenances during primary starting, it is longer to cultivate domestication, start slowlyer, and the mud return-flow system need be set, also sludge bulking may take place, in case take place, consequence is serious, and simultaneously, the sewage foam influences charging efficiency.Moreover disposable construction investment is big, the processing cost height, and current consumption is bigger.
Summary of the invention
The object of the present invention is to provide a kind of investment little, running cost is low, and that can carry out purification of water quality safe, harmless, thoroughly, efficiently utilizes the microbial treatment process sewage.
The present invention utilizes the microbial treatment process sewage to divide following three phases to carry out:
1) dynamic cultivation stage of initial stage, the pH value of at first controlling sewage is 6～9,4～30 ℃ of temperature, then sewage is introduced treatment zone, circulation and aerator by pump are promoted to 1.5～2.0mg/L with the oxygen in the sewage, drop into microorganism complex, and input amount is 5～50g/m
3Sewage, through 7～15 days cultivation, treated water after up to standard began discharging, is generally first discharge standard, showed the success of dynamic cultivation stage of initial stage this moment.
2) dynamic cultivation stage enters treatment zone with sewage, handles continuously and discharges, and add microorganism complex, adds secondary in one day, and otal investment is 5～20g/m
3Sewage, and oxygen level is 1.5～2.0mg/L in the maintenance sewage, the residence time of sewage in treatment zone is 8～10 hours, shows dynamic cultivation success, and keeps 8～10 days treatment times.
3) in the dynamic operation stage, successively dispose of sewage every day, and add microorganism complex, added secondary in one day, and otal investment is 2～15g/m
3Sewage, and oxygen level is 1.52.0mg/L in the maintenance sewage, the residence time of sewage in treatment zone is 6～8 hours, carries out uninterrupted sewage disposal like this.
Wherein, its composition of microorganism complex is yeast bacteria 1～25, milk-acid bacteria 1～5, actinomycetes 2～10, nitrifier 5～15, denitrifying bacterium 5～18, nitrite bacteria 0～15, photosynthetic bacteria 5～15, ammonia oxidation bacteria 0～12, Ammonifying bacteria 0～15, the dried bacterium 15～30 of gemma, false monospore bacillus 2～8, methanogen 0～9 by weight percentage.Above microorganism is prior art, selects different microorganism combinations according to different sewage, constitutes the microbial compound preparation that is suitable for handling such sewage.
The present invention utilizes its advantage of microbial treatment process sewage to be, in a single day this microbial compound preparation drops in the sewage, can be " activated " in the short period of time, microorganism after " activation " is through how much multiple propagation, organism in the sewage had extremely strong biodegradability, technical process is simple, be convenient to safeguard, easy and simple to handle, nontoxic, harmless, do not produce the solid microbial of secondary pollution, can safety, finish purification of water quality thoroughly, efficiently, and one-time investment is few, processing cost is low, is suitable for handling all kinds of sewage.
