Description
Technical field
The invention belongs to water treatment field, be specifically related to the removal method that a kind of softening agent sewage promptly contains phthalic ester sewage.
Background technology
Big quantity research confirms that human dysgenesia, heteroplasia, some cancer and immunity system, nervous system disorders are relevant with environment incretion interferent.Phthalic ester (Phthalic acid esters, or Phthalates are called for short PAEs, claim phthalate again) is one of most important endocrine disrupter in the water surrounding.In industry, mainly as the softening agent and the tenderizer of plastics, the addition in the PVC polyethylene plastic products reaches 20%～50% to the PAEs compound.Because PAEs is not aggregated in the matrix of plastics, thereby in production, use and treating processes, PAEs is released in the environment, and atmosphere, water body, soil, farm crop and organism etc. are polluted.
In August, 1998, U.S. EPA has announced that 67 kinds (classes) from 86000 kinds of commercial chemical, filtering out jeopardize human body and biological environment incretion interferent, and PAEs is formally listed in wherein.Also comprise 3 kinds of phthalate compounds (dimethyl phthalate (DMP), n-butyl phthalate (DBP) and DOP (DEP) in China's environment priority pollutant Black List.
PAEs is easy to biomagnification, readily biodegradable not, and methods such as traditional flocculation, chlorination all are difficult for removing this compounds, and the lower and long processing period of biological treatment efficient.In recent years, people have been developed the various coupling techniques of chemical/physical efficiently, like gac and combination process thereof, TiO
Z/ UV co-oxidation technology, plasma treatment, microwave irradiation technology, high-energy radiation technology etc.Uv/ozone oxidation technology is exactly wherein a kind of.It has conveniently fast, need not add new advantages such as chemical substance (ozonizer can be connected with oxygenerator, directly from atmosphere, obtains oxygen), and current consumption is big, the not high shortcoming of mineralization degree but exist.The Study on degradation of DMP is shown that ozone molecule mainly is to come DMP's in the oxidizing water with the mode of direct attack according to us.Its oxidising process is similar to biological degradation, at first oxide side chain is generated phthalic acid, and then the open loop of further degrading, and finally generates water and CO
2Compare with simple ozone oxidation, uv/ozone coupling technology has improved clearance about 10%.The uv/ozone degradation process is first quick and back slow, and intermediate product reaches the climax in about 1/3 time, and intermediate product continues mineralising in remaining 2/3 time, reduces gradually.
As first trophic level of aquatic ecosystem, algae plays an important role with stable for balance of ecosystem, particularly in eutrophication water, because nutritive salt and organic matter increase greatly, makes a large amount of numerous lifes of algae.Existing research shows that algae has certain enrichment and Degradation to the organic pollutant of water body.Even wherein one type of Chlorella vulgaris.According to research, Chlorella vulgaris is insensitive to the toxic action of DMP, its EC
50Be 330mg.L
-1More than, and when lower concentration (10.0mg.L
-1) DMP is had significant Degradation, the 72h degradation rate reaches more than 60%.Chlorella has one section adaptation time and DeR process in the starting stage of contact DMP.On degradation speed, experience slow, a fast process.But in general, adopt chlorella degraded DMP consuming time longer merely.
Summary of the invention
The objective of the invention is on the basis of existing technology, provide a kind of uv/ozone/chlorella degraded recombining process to remove the method for phthalic ester in the water.This law proceeds to 0.3～0.4 times of treatment time in uv/ozone technology, the water that is rich in the degraded intermediate product is injected the bead algae culture pond carry out follow-up biological degradation the peak times that the intermediate product of promptly degrading occurs, and is translated into frond, mineralising is water and CO
2This law is compared with simple uv/ozone technology or biological degradation, and energy consumption lowers greatly, the shortening of processing cycle, the also corresponding increase of treatment capacity.
The object of the invention can reach through following measure:
A kind of uv/ozone/chlorella degraded recombining process is removed the method for phthalic ester in the water, and it comprises the steps:
1) elder generation takes a sample from the polluted water that contains phthalic ester and carries out the trial test of uv/ozone process integration, and confirm uv/ozone process integration parameter: the clearance of phthalic ester reaches 90% o'clock treatment time T in uitraviolet intensity, ozone feeding amount and the water;
2) under the condition of above-mentioned uitraviolet intensity and ozone feeding amount, adopt the uv/ozone process integration that the said polluted water that contains phthalic ester is carried out pre-treatment, the treatment time is 0.3～0.4T;
3) during the water after the pre-treatment reinjected the bead algae culture pond, biodegrade was handled under the effect of chlorella.
The present invention comprises that (step 1) and pre-treatment and biological treatment (step 2 and 3), trial test can be confirmed treatment condition, thereby reference is provided for extensive formal the processing to the sample trial test.When uv/ozone process integration of the present invention is meant that treating treating water carries out the uv irradiating processing, also it is carried out ozonation aerated processing.
The concentration that this law is handled to contain phthalic ester in the polluted water of phthalic ester is 1～10mg.L
-1If contain when containing more solid matter or organism in the polluted water of phthalic ester, can the polluted water that contain phthalic ester be precipitated earlier and filters (as water being injected the water reservoir deposition, filtering), carry out trial test and pre-treatment again.
Uitraviolet intensity in trial test is 135～270 μ W.cm
-2, ozone feeding amount is 2.0～10.0mg.h
-1.L
-1Water sample is carried out trial test; Be not only in order to obtain uv/ozone process integration condition; Especially in order to confirm the time of 90% clearance; And then obtain the uv/ozone process integration reach the peak times that the degraded intermediate product occurs (promptly 0.3～0.4T), be utilized in and have a large amount of these phenomenons of degraded intermediate product in this peak times, for follow-up chlorella biodegradation process provides favourable condition.
Uv/ozone process integration to 0.3～0.4 times T is after the treatment time, after the peak times that the intermediate product of promptly degrading occurs, the water that is rich in the degraded intermediate product injected the bead algae culture pond carry out follow-up biological degradation, is translated into frond, mineralising is water and CO
