Description
(1) technical field
The present invention relates to a kind ofly be used for lacking the complex active phosphorus source additive of phosphorus wastewater treatment and in the application that lacks the phosphorus wastewater treatment.
(2) background technology
Papermaking technology is one of four inventions of Ancient Times in China, is Ancient Times in China working people crystallization of wisdom; Modern age, pulp and paper industry was also made important contribution for the development of China's national economy.Yet when the rarity of China was applied to today industrial, the Nature had but been paid painful cost.The pollution of pulping and paper-making makes many regional water industry, Agricultural Development and people ' s health be subjected to serious harm, and therefore, country continues to increase the law enforcement dynamics of environment protection.Particularly the paper industry of China has obtained fast development over past ten years, and paper industry is also more and more serious to the pollution of environment, and the pollution problem of solution pulping and paper-making is very urgent.
Paper-making effluent adopts the second-stage treatment technology of physics-biochemistry usually, so that water quality reaches emission standard.Yet, because pulp and paper industry waste water generally lacks phosphorus, cause wastewater treatment mesophytization section microbial nutrition unbalance, though it is industrial through adding the additional phosphorus nutrition of medicines such as phosphoric acid salt or industrial phosphoric acid, but have problems: (1) microorganism only can utilize dissolved phosphorus nutrition material, yet general industry phosphoric acid or phosphoric acid salt easily with waste water in calcium salt formation precipitation of hydroxyapatite, cause phosphorus nutrition solidified problem, microorganism can't absorb; (2) react just because of metal ions such as phosphoric acid class material and calcium salts, inorganic components increases in the mud, and sludge settling is poor, influences the aeration tank and handles; (3) general phosphoric acid salt consumption is big, and labor strength is higher, and owing to microorganism specific absorption in the active sludge is not high, there is the phenomenon that exceeds standard on the contrary in the water outlet total phosphorus; (4) winter temperature is low, easily freezes, and the execute-in-place condition is more abominable.
(3) summary of the invention
The present invention seeks to provides a kind of complex active phosphorus source additive that microorganism active utilization ratio height, effect are lasting, can improve sludge activity that improves for the improvement that lacks phosphorus waste water.
The technical solution used in the present invention is:
A kind of complex active phosphorus source additive that is used for lacking the phosphorus wastewater treatment, contain the following component of mass content:
Sodium salts humic acids 0.01%～0.5% (w/v)
Yelkin TTS 0.05%～0.5% (w/v)
Phosphatase 24 0%～60% (w/v)
Solvent is a water;
Described phosphoric acid quality content P
2O
5The quality meter, above-mentioned per-cent is the quality volume percent, and certain constituent mass volumn concentration is 1%, contains this component 1g in the expression 100mL solution.
The utilization ratio that the raising microbic activity reaches the phosphorus source becomes the key that addresses the above problem.Humic acid substance has been widely used in fields such as agricultural, medicine, industry, and especially humic acid substance constitutes the phosphate fertilizer mixture, can provide phosphorus source efficiently for agriculture production.Same, humic acids also can provide phosphorus source efficiently for lacking the phosphorus wastewater treatment.Humic acids is a kind of material that extensively is present in soil, plant, the water body, and the macromolecular basic structure of humic acids is aromatic ring and alicyclic ring, is connected with functional groups such as carboxyl, hydroxyl, carbonyl, quinonyl, methoxyl group on the ring.Humic acids can with metal ion generation complex reaction, thereby preventing that the little metal ion that contains in the waste water and phosphate radical from reacting generates precipitation, improves the utilization ratio of microorganism to phosphorus.Humic acids is divided into xanthohumic acid, ulmic acid and Ulmic acids, wherein has only the water-soluble better of expensive xanthohumic acid.For saving cost, improve its solvability, so the present invention adopts Sodium salts humic acids as binder component.Concrete complex reaction is as follows:

Phosphatide is the breakdown products of cytolemma, cheap and easy to get, phosphatide can be hydrolyzed to glycerine, lipid acid, phosphoric acid and various amino alcohol (as choline, thanomin, Serine etc.) through various Phospholipid hydrolase effects in microbe, thereby provides organophosphorus source and other growth desired nutritional material for microorganism.
Further, described complex active phosphorus source additive also contains the following component of mass content:
ATP disodium salt 0.005%～0.1% (w/v)
Nucleotide 0.005%～0.1% (w/v)
Citric acid 0.05%～0.4% (w/v)
Trace nutrients such as ATP, Nucleotide, citric acid can directly be absorbed by microorganism, accelerate the microbial growth breeding, thereby improve the activity of mud.
Preferably, described complex active phosphorus source additive is made up of the following component of mass content:
Sodium salts humic acids 0.1%～0.2% (w/v)
Yelkin TTS 0.05%～0.2% (w/v)
ATP disodium salt 0.01%～0.1% (w/v)
