Temperature is to affect growth of microorganism, breeding and a metabolic key factor.Petroleum hydrocarbon is degraded the catalytic action by means of enzyme by microorganism, and the activity of enzyme only could be played within the scope of certain temperature.The too low meeting of temperature makes enzymatic activity be suppressed, and cell and metabolic activity weaken.Temperature rises, and makes the enzymatic activity of microorganism strengthen, and cell growth rate is accelerated.But after exceeding optimal temperature, on the one hand, the activity decrease of enzyme, the enzyme even having inactivates, on the other hand, in culture fluid, dissolved oxygen concentration reduces and also results in growth rate and slow down.Every kind of microorganism can only grow in certain scope, and have its growth, breed the fastest optimum growth temperature.Therefore, select suitable temperature most important to the raising of the growth and breeding of microorganism and the degradation capability of pollutant thereof.
(3) moisture control
In soil, water content is too low, and microorganism can not get sufficient water supply, and cytoactive is suppressed, and metabolic rate reduces；Moisture is too high, and effective capillary void spaces is full of by moisture, hinders circulation and the supply of oxygen of air.When in soil, moisture content is 30%～90%, to petroleum hydrocarbon, organic degradation rate is higher in microorganism.
(4) acid-base value regulation
In soil, pH value excursion is big, it is 2.5～11.0, most of heterotrophic bacterias and fungus wash the environment of neutral range, pH value mainly affects intracellular enzymatic activity to the impact of growth of microorganism, even can have influence on DNA, RNA, the stability of ATP and synthesis, the highest or the lowest degradation capability that all can affect microorganism of pH value, so in the middle of Practical Project uses, for the growing environment good to microorganism offer, improve the microorganism degradation efficiency to hydrocarbon, need to add pH buffer agent to waste residue, regulation microorganism PAH degraded is just when for 7.5～7.8.Processing procedure changes according to pH value, needs suitably to regulate soil pH.
(5) nutritional solution, fertilizer
In petroleum-contaminated soil, nitrogen source and phosphorus source often become the restriction factor of microbial degradation hydrocarbon.Because containing substantial amounts of carbon and hydrogen in hydrocarbon, then nitrogen and P elements are the principal elements affecting bacterial growth breeding, N, P amount that in oil, it is required that carbon converts completely can calculate according to C:N:P ratio in Cytoplasm material, ratio needed for C:N:P ratio does not reaches bacterial metabolism in soil, then can the accretion rate of restricting bacterial, thus restrict the degraded that greasy filth pollutes.
