4results about How to "Solve the odor problem" patented technology

The utility model relates to the field of pet supplies, in particular to a cat toilet with an automatic flushing and pollution discharge function, which comprises a bedpan main body and a bedpan pollution discharge hole, the bedpan main body is defined by a bedpan bottom surface and peripheral side walls, a middle concave bedpan groove is arranged on the inner bottom surface of the bedpan main body, and the middle concave bedpan groove is connected with the bedpan pollution discharge hole. A peripheral concave defecation groove is formed in the inner periphery of the bedpan, close to the side wall of the bedpan, and is communicated with one end of a middle concave defecation groove; a sensing device position is arranged on the side wall of the bedpan body and used for installing a sensor, sensing the defecation behavior of a cat and cooperatively controlling flushing, a clean water flushing water outlet groove is formed in one side wall in the bedpan body, and the clean water flushing water outlet groove is connected with an external water supply system. The bedpan base for supporting the bedpan body and the defecation bin are arranged below the bedpan main body, and sewage treated by the defecation bin can be discharged through a sewer with a smaller pipe diameter. The whole set of the cat toilet is innovatively combined, and automatic cleaning work of excrement of the cat in the toilet without manual intervention in the whole process is achieved.

The invention discloses a composite deodorizing agent and a preparation method thereof, the composite deodorizing agent is composed of the following components: a plant extraction component, the plant extraction component comprises a tea extract, a ginger extract, an oak leaf extract, a lavender extract, a licorice extract, a green persimmon extract, a pine bamboo extract and a schizonepeta extract; the microbial component comprises a proteolytic enzyme, an aldehyde hunting factor and nano diatomite; the auxiliaries comprise a stabilizer, titanium dioxide with a topological structure, syringol, a fermented rice product, an odor modifier, a chelating agent, an antioxidant, a plant preservative and a solvent. The deodorization effect of plants and microorganisms can be effectively integrated, the deodorization capacity after compounding is improved, and the safe and environment-friendly deodorization process is achieved.

The application discloses a method for preparing formed fuel by mixing semi-dried sludge and oil-tea camellia fruit hulls, and the method comprises the following steps: (1) washing and drying the oil-tea camellia fruit hulls, then crushing and sieving the oil-tea camellia fruit hulls to obtain oil-tea camellia fruit hull powder; drying high-moisture sludge to obtain semi-dried sludge; (2) baking the oil-tea camellia fruit hull powder under a mixed atmosphere of oxygen and nitrogen to obtain baked oil-tea camellia fruit hulls, or pyrolyzing the oil-tea camellia fruit hull powder under a nitrogen atmosphere to obtain oil-tea camellia fruit hull biochar; (3) mixing and stirring the semi-dried sludge and the baked oil-tea camellia fruit hulls or the oil-tea camellia fruit hull biochar, uniformly placing water, and then preparing formed fuel. The method is simple, easy to operate and low in cost, the prepared formed fuel particles can realize rapid reduction of urban sludge and recycling of energy, and the method has the advantages of low energy consumption, high particle strength, no pollution and the like when the formed particles are prepared.

The invention particularly relates to a screening method of urease inhibitor producing bacteria. The screening method comprises the following steps: screening ammonia nitrogen efficient bacteria; screening strains which do not produce urease; screening of urease inhibitor producing strains, wherein the strains with high urease activity inhibition rate are selected as the urease inhibitor producing strains. According to the screening method of the urease inhibitor producing bacteria, ammonia nitrogen efficient bacteria are firstly screened, then urease inhibitor producing strains are screened, generation of ammonia gas is controlled from the source, NH3 is decomposed from the terminal, and therefore the problem of stink of the ammonia gas can be more efficiently solved; according to the secondary screening method for the strains not producing urease, the defect that alkali-producing strains not producing urease are excluded by a urea-phenol red plate can be avoided, the strains not producing urease can be relatively comprehensively screened, overflowing NH3 is detected, and the secondary screening method is relatively suitable for an odor generation scene; a urease material of a urease inhibitor production strain is a supernatant obtained after centrifugation of a bacterial liquid, mainly a bio-enzyme rather than a thallus, and interference of antagonism between bacteria can be reduced.
