Description

A kind of zoogloea structure and active mikrobe of improving mud promotes nutrition agent
Technical field
The present invention relates to the wastewater biochemical treatment technology, the medicament that obtains can improve the zoogloea structure of active sludge, and promotes the breeding and the amplification of probiotics in the active sludge, thereby improves the oxidative decomposition capacity of active sludge to pollutent, and important productive value is arranged.
Background technology
Activated Sludge Process is a kind of most widely used waste water aerobic biochemical processing, and it mainly is made up of aeration tank, secondary sedimentation basins, aerating system and mud return-flow system etc.; Its principal feature is that waste water gets into the aeration tank with the active sludge that refluxes in secondary sedimentation basins bottom simultaneously behind primary sedimentation pond, carries out aeration, and it is fully contacted with waste water, through absorption and two steps of oxidation with the decontamination process of completion to waste water.Because active sludge has biological character, examines under a microscope mainly and is made up of mikrobe, protozoon, wheel animalcule and some impurity, can also observe the appearance of oligochaetes and nematode sometimes; In order to keep the vigor of activated sludge absorption and oxidation, except controlling conditions such as suitable pH, temperature, dissolved oxygen, the certain nutrition material to be arranged also; The energy as microorganism growth, breeding; Requirement has suitable carbon, nitrogen, phosphorus ratio, owing to lack micro-nutrients, and contains certain toxicity for most trade effluent; This all influences the microorganisms of active sludge in the biological treatment of waste water system; Finally can cause the failure of wastewater treatment, so for the shortage of nutritive substance in the waste water, conventional way is in the aeration tank, to add liquefied ammonia, urea, NH 4NO 3, (NH 4) 2SO 4And H 3PO 4, but these nutritive substance kinds are single, make the initial failure period of Waste Water Treatment longer, and it is relatively poor that active sludge recovers last effect slower and stable aerated pond, and for certain toxic water body is arranged, these materials do not have obvious effects.
Literature search discloses:

Control Example of the present invention is described further.
Embodiment
Preparation of raw material: get 65.0 parts of yellow humic acid organic sequestering agents with parts by weight, 10.0 parts of Semen Maydis powder, 10.0 parts of yeast powders, 1.0 parts of Trisodium Citrates, 1.0 parts of dithiocarbamate salt, 0.8 part of phytokinin, NH 4NO 38.0 part, Na 2HPO 412H 22.0 parts of O, KH 2PO 41.0 part, MgSO 47H 20.8 part of O, CoCl 26H 20.4 part of O;
Preparation: above-mentioned raw materials is added in the reaction kettle successively, and normal temperature, normal pressure with 60 rev/mins of speed, stirred 80 minutes, evenly, promptly got mikrobe and promoted nutrition agent.
The use key points for operation of this product:
1) measures sludge settling ratio; Observing color, smell state and flocculation, the precipitation process of active sludge, and with the dynamic change of the zoogloea structure mikrobe phase of optics sediments microscope inspection active sludge: the active sludge of standard state is a khaki color, and smell is the earth smell; Sedimentation is rapid; According to the observed and recorded result of this sewage work, can judge the running condition of aeration tank again, the active sludge of the explanation aeration tank system that is not inconsistent with conventional phenomenon is worsening; Need to add mikrobe and promote nutrition agent, to improve active sludge zoogloea structure in the aeration tank.
2) detection gets into the BOD5 and the COD of the former water pollutant concentration of aeration tank, calculates the ratio of B/C; < 0.3 waste water belongs to waste water difficult for biological degradation to BOD/>COD, and this moment, mikrobe promoted that the dosage of nutrition agent needs to strengthen, and the time of adding needs to prolong, and with repairing activity sludge bacteria micelle structure, makes it return to optimum regime; And BOD/COD 0.3 waste water belongs to biodegradable waste water, this moment, mikrobe promoted long-time and a spot of the adding of nutrition agent can guarantee the long steady running of aeration tank system.
3) this product adds the tap water dissolving earlier in use, and its water promotes the nutrition agent dosage than being 10:2 with mikrobe; Open stirring with 60 rev/mins of speed, promote nutrition agent evenly to add mikrobe, stirred 35 minutes, it is fully dissolved,, do not influence result of use if solution muddiness occurs and belongs to normal phenomenon along the tangential direction of water.
4) promote nutrition agent to be added in the returned sluge mikrobe through dosing pump, and continue to add that the big I of dosage is accomplished through the aperture of regulating dosing pump; Promote in the nutrition agent process adding mikrobe, continue to observe sludge settling ratio, MLSS and COD, up to the aeration tank treatment system water outlet up to standard, and steady running.
5) product use range can be used as the biological stablizer of debugging auxiliary agent and biochemical system run duration.
The WWT experimental verification:
The water disposal system of Urumchi petrifaction sewage water purification plant, active sludge color are Vandyke brown, and a small amount of beans shape worm and lamblia and amoeba are found in microscopic examination, and a small amount of mycelia is arranged between flco; Promote nutrition agent to be added in the returned sluge mikrobe through dosing pump, the amount by the mikrobe promotion nutrition agent that contains 12ppm in the aeration tank continues to add, and the big I of dosage is through regulating the aperture completion of dosing pump; After one month, the mud color is a khaki color, and structure is tight, leaves standstill the flco that occurs a moment and obviously increases, and settling velocity is fast, and supernatant liquid is limpid, can clearly see zoogloea pinniform edge; Microscopic examination has ciliate, roaming worm, solely contract worm and a small amount of campanularian, can find out that from the biophasic variation of active sludge adding of medicament produces a desired effect.
In addition, observe the COD degraded situation of waste water continuously, can find out that like Fig. 1 biochemical system is impacted during late May, it is very poor that treatment effect becomes, and water outlet COD value does not far reach index request.
Promote nutrition agent from beginning on June 3 in biochemistry pool mikrobe on probation; The medicament startup needs certain hour, and medicament gets into strengthens after date, and trial effect clearly; Circle exposes to the sun and little water COD value that exposes constantly reduces; And fluctuation diminishes, and the circle Chi Hewei that exposes to the sun exposed to the sun pond water outlet COD value less than 120mg/L June 18, had reached the emission request (Fig. 2) of product beta test.
This product meets national company standard: Q/DL
