2) complexing: sewage is drained in complexing pond, according to 1kg complexing agent: the ratio of 1 ton of sewage adds complexing agent, subsequently with 200-300 turn/speed of min stirs 30-60min, then leaves standstill 6-8 hour; Wherein, complexing agent is prepared as follows and forms: get sodium alginate, aluminum oxide, potassium humate, ferrous sulfate according to the mass ratio of 1:2:3:3, mix together;
3) bio-oxidation: the sewage behind complexing pond is drained into bio-oxidation pond, first the pH of sewage is regulated to be 7-8, then add bacteria agent 10 grams by every cubic metre of liquid at every turn, add 1 every day, add two days later continuously, leave standstill five days again, liquid is filtered by plate filter, finally discharges; Wherein, bacteria agent is prepared as follows and forms:
Thiobacillus denitrificans, pseudomonas aeruginosa, bacillus cereus or bacillus megaterium being trained respectively concentration is 1 × 10
8the bacterium liquid of individual/ml, mixes according to the volume ratio of 1:2:2:2, then with sawdust according to the quality of 1:2 than mixing and stirring, finally carry out cryodrying, drying temperature is 20-30 DEG C, and after dry, water content is 20%; Obtain.
Bacterial classification of the present invention belongs to conventional bacterial strain, all can buy from commercial sources such as Chinese General Microbiological Culture preservation administrative center (CGMCC) or American Type Culture collection warehousings (ATCC) and obtain.The enlarged culturing of each bacterial classification of the present invention is the cellar culture mode of this area, is not innovative point of the present invention, does not describe in detail herein.
The beneficial effect that the present invention obtains mainly comprises:
Invention formulation comprises complexing agent and bacteria agent, with low cost, be easy to get, can removal heavy metal and industrial COD effectively, and easily prepares; Reasonable compatibility between each bacterial classification in bacteria agent of the present invention, symbiosis is coordinated, mutually not antagonism, can effectively reduce industrial COD; Complex compound of the present invention is composite by raw material, plays synergy, has broad spectrum, can effectively remove the heavy metals such as nickel, chromium, copper, zinc; Treatment process of the present invention is simple, decreases floor space, reduces investment outlay, and is easy to operational management.
