Abstract
Methods for the biological treatment of sewage in a sewage treatment plant, of wastestreams and of ponds are disclosed. The methods employ a composition comprising active amounts of an enzyme mixture, B. subtilis and P. fluorescens, and a nutrient source having a COD of 10,000 mg/kg or less, of which one source is used mushroom compost. The composition is first activated in fresh water, is then acclimated in a waste moiety, and the acclimated mixture is then used to treat the main body of the waste, such as sewage sludge, a wastestream or a pond.
Claims27
A method for the continuous biological treatment of sewage to reduce the volume of aqueous sludge in a sewage treatment plant comprising the steps of:
- (A) providing a mixture comprising
- (1) active amounts of an enzyme mixture comprising amylase, lipase, protease, and cellulase;
- (2) active amounts of bacteria comprising Bacillus subtilis and Pseudomonas fluorescens;
- and
- (3) a nutrient source having a chemical oxygen demand of 10,000 mg/kg or less;
- (B) immersing said mixture in fresh water for from about 6 hours to about 48 hours at a temperature of at least 60.degree. F. to produce an activated mixture;
- (C) mixing a volume of aqueous sludge from said sewage treatment plant with a volume of said activated mixture for from about 6 hours to about 48 hours at a temperature of at least 60.degree. F. to produce an acclimated mixture;
- and
- (D) adding a volume of said acclimated mixture of step (C) to a sludge treatment tank in said sewage treatment plant and maintaining said mixture and said sludge in contact at a temperature of at least 60.degree. F. for at least two days to reduce the volume of aqueous sludge and suspended solids in the sewage treatment plant.

- (B) immersing said mixture in fresh water for from about 6 hours to about 48 hours at a temperature of at least 60.degree. F. to produce an activated mixture;
- (C) mixing a volume of aqueous sludge taken from a sludge digester in said sewage treatment plant with a volume of said activated mixture for from about 6 hours to about 48 hours at a temperature of at least 90.degree. F. to produce an acclimated mixture;
- (D) adding a volume of said acclimated mixture of step (C) to a sludge digester tank in said sewage treatment plant and maintaining said mixture and said sludge in contact at a temperature of at least 90.degree. F. for at least two days to reduce the volume of aqueous sludge, hence suspended solids in the sewage treatment plant;
- and wherein steps (B) to (D) are repeated regularly to reduce and achieve a reduced volume of aqueous sludge and suspended solids in the sewage treatment plant.
A method for the continuous biological treatment and purification of a wastewater stream containing organic contaminants comprising the steps of:
- (A) providing a mixture comprising
- (1) active amounts of an enzyme mixture comprising amylase, lipase, protease, and cellulase;
- (2) active amounts of bacteria comprising Bacillus subtilis and Pseudomonas fluorescens;
- and
- (3) a nutrient source having a chemical oxygen demand of less than about 10,000 mg/kg;
- (B) immersing said mixture in fresh water for from about 6 hours to about 48 hours at a temperature of at least 60.degree. F. to produce an activated mixture;
- (C) mixing a volume of said activated mixture with a volume of wastewater from said stream for from about 6 hours to about 48 hours at a temperature of at least about 60.degree. F. to produce an acclimated mixture;
- and
- (D) adding acclimated mixture of step (C) to the wastewater stream and maintaining contact for at least about three hours to reduce the organic contaminants.
A composition for treating waste and contaminants comprising:
- an enzyme mixture comprising active amounts of amylase, lipase, protease, and cellulase;
- bacteria comprising active amounts of Bacillus subtilis and Pseudomonas fluorescens;
- and
- used mushroom compost.
A method for the biological treatment and purification of a body of water containing limited dissolved oxygen and high biological oxygen demand comprising the steps of:
- (A) contacting freshwater with an activatable mixture comprising an enzyme mixture comprising amylase, lipase, protease, and cellulase;
- bacteria comprising Bacillus subtilis and Pseudomonas fluorescens;
- and compost having a chemical oxygen demand of 10,000 mg/kg or less for from about 6 hours to about 48 hours to produce an activated mixture;
- (B) acclimating a volume of said activated mixture with a volume of water taken from said body of water for from about 6 hours to about 48 hours at an ambient temperature to produce an acclimated mixture;
- (C) adding a volume of the acclimated mixture of step (B) to the body of water;
- and
- (D) repeating steps (A) through (C) as necessary repeatedly to deliver volumes of acclimated mixtures to said body of water until the dissolved oxygen is increased and the biological oxygen demand is reduced, and they fall within predetermined acceptable levels.
