Abstract
The invention discloses an aeration tank for reducing the ammonia nitrogen content in sewage according to the ammonia nitrogen biological degradation technology, and a treating method. The aeration tank comprises an aeration tank body; an aeration flow passage is formed in the aeration tank body, and comprises a first corridor, a second corridor, a third corridor, a fourth corridor, a fifth corridor and a sixth corridor which are connected with one another end to end in sequence; the tail end of the fourth corridor or the head end of the fifth corridor is connected with one end of a return pipe; a muddy water mixing zone is connected with the other end of the return pipe. Due to the additionally arranged return pipe, the original push flowing type reaction pattern is replaced with a semi-mixing reaction pattern, so that a growth environment beneficial for microbial ammonia nitrogen degradation reaction fungi is formed in the aeration flow passage. Therefore, the ammonia nitrogen content of output water is greatly reduced to meet emission standard of treated water.
Description
Technical field
The present invention relates to a kind for the treatment of process of sewage, relate in particular to aeration tank and treatment process that the ammonia nitrogen biodegradation technique reduces the sewage ammonia nitrogen amount.
Background technology
The main source that the textile industry of dyeing waste water is polluted.Along with the extensive application of fiber product, slurry, dyestuff, chemical assistant, the composition of waste water constantly changes, and intractability also increases.Water outlet ammonia nitrogen amount is one of index of weighing the water outlet discharge after treatment.But, according to traditional sewage disposal, not only exist the fluctuation of water outlet ammonia nitrogen index larger, and its ammonia nitrogen amount substantially exceed discharge index.Therefore dyeing waste water is carried out cost-effective processing and makes the ammonia nitrogen amount reach the difficult problem that discharge index becomes wastewater treatment.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide the ammonia nitrogen biodegradation technique to reduce aeration tank and the treatment process of sewage ammonia nitrogen amount, it makes aeration tank pulling flow type reaction pattern originally change meromict formula reaction pattern into by the return line of setting up, thereby the index that makes COD, BOD, DO in each gallery of aeration runner distributes and changes, in the aeration runner, be formed with the growing environment that is beneficial to microorganism ammonia nitrogen degradation reaction bacterium, thereby the water greatly reduced after water outlet ammonia nitrogen amount makes to process reaches emission standard.
The present invention is the purpose that reaches above-mentioned, and the present invention adopts following technical scheme:
The ammonia nitrogen biodegradation technique reduces the aeration tank of sewage ammonia nitrogen amount, comprises aeration tank, on described aeration tank, rising pipe is installed, and described aeration tank is connected with the muddy water mixing zone; In described aeration tank, offer the aeration runner, described aeration runner comprises the first gallery, the second gallery, the 3rd gallery, the 4th gallery, the 5th gallery, the 6th gallery, and described the first gallery, the second gallery, the 3rd gallery, the 4th gallery, the 5th gallery, the 6th gallery join end to end successively, wherein said the first gallery is connected with the muddy water mixing zone, and described the 6th gallery is connected with rising pipe; The head end of the end of described the 4th gallery or the 5th gallery is connected with an end of return line, and described muddy water mixing zone is connected with the other end of return line.
In described aeration tank, offer 2 aeration runners.
The ammonia nitrogen biodegradation technique reduces the treatment process of the aeration tank of sewage ammonia nitrogen amount to sewage, comprise the steps: that at first sewage and mud are transported to the muddy water mixing zone from water-in and mud inlet respectively to be mixed, then will be mixed with the sewage transport of mud to the interior aeration of the first gallery of aeration runner, then will be mixed with the sewage of mud successively by the second gallery, the 3rd gallery, the 4th gallery aeration; When the sewage that is mixed with mud after the 4th gallery aeration is complete, the sewage that is mixed with mud at the head end of the end of the 4th gallery or the 5th gallery is back to by return line the sewage that the muddy water mixing zone is directly diluted in the muddy water mixing zone, and with the sewage of muddy water mixing zone by aeration runner aeration again; The sewage that is mixed with mud at the head end of the end of the 4th gallery or the 5th gallery is discharged by the 5th gallery, the 6th gallery, rising pipe successively by the sewage that return line refluxes.
The sewage backflow ratio that the head end of the end of described the 4th gallery or the 5th gallery is mixed with mud is 60%-100%.
Beneficial effect of the present invention is: the invention provides aeration tank and treatment process that the ammonia nitrogen biodegradation technique reduces the sewage ammonia nitrogen amount, it makes aeration tank pulling flow type reaction pattern originally change meromict formula reaction pattern into by the return line of setting up, thereby the index that makes COD, BOD, DO in each gallery of aeration runner distributes and changes, in the aeration runner, be formed with the growing environment that is beneficial to microorganism ammonia nitrogen degradation reaction bacterium, thereby the water greatly reduced after water outlet ammonia nitrogen amount makes to process reaches emission standard.
