The invention discloses a composite microorganism viable bacteria preparation, which contains pediococcus, yeast and bacillus with the total bacteria count of more than 1 billion per gram. The invention also discloses a method for preparing the composite microorganism viable bacteria preparation, which comprises the following steps: performing amplification liquid culture on various strains respectively according to a conventional method in the field; mixing the materials according to a required proportion; and performing solid fermentation, drying and pulverization to obtain the composite microorganism viable bacteria preparation. The invention also discloses application of the composite microorganism viable bacteria preparation in preparing an organic waste water purifying agent and an aquaculture water body purifying agent, a deodorizer, a degreasing agent or an agent for removing pipe blockages for the hygiene of a refuse tip, a public place, an agricultural product market or a kitchen, feed additives in poultry and animal husbandry or pet culture, and preparations for controlling agricultural microorganism diseases. The composite microorganism viable bacteria preparation can effectively decompose a large amount of putrescent organic matters, inhibit the growth of harmful microorganisms and eliminate peculiar smells, and has the characteristics of high ammonia nitrogen removal rate, no generation of residual sludge, effective deodorization, low cost and the like.

The invention relates to a preparation and a treatment method, and especially relates to a preparation and a method for drying sludge through deep dehydrating. The preparation comprises: 0.000002 to 0.00001 parts of an organic polymeric flocculants, 0.00025 to 0.0025 parts of a coagulating modifier, 0.0005 to 0.00375 parts of a sterilizing deodorant, and 0.00025 to 0.0025 parts of a nucleating converting agent. The method comprises the following steps: a sludge gravity thickening initial dehydrating step, a sludge regulating step, a mechanical press-filtrating step, and a filtrate refluxing step. With the preparation and the method provided by the present invention, sludge deep dehydrating processes can be carried out in series, processing efficiency can be improved, and energy consumption can be reduced. The controllability of the method is high. With the method, recycling is realized.

The invention discloses sludge coal ash high-strength ceramsite and a preparation method thereof. By using sludge and coal ash as main raw materials, the ceramsite is prepared by mixing, prilling and calcining by synergic match with an additive. The ceramsite is prepared from the following raw materials in parts by weight: 40-70 parts of sludge, 30-55 parts of coal ash, 0.5-1.5 parts of calcium sulphoaluminate, 0.5-1 part of phthalate, 1-3 parts of water glass and 0.5-1 part of a deodorant, wherein the water content of sludge is controlled within 35-50wt%. The sludge coal ash high-strength ceramsite is prepared by the following steps: mixing the materials; prilling; drying; calcining; and cooling. The ceramsite disclosed by the invention is economical, environment-friendly, efficient and energy-saving and scientific and reasonable in match of components of raw materials, and the prepared sludge coal ash high-strength ceramsite has the advantages of high cylinder compressive strength and high absorption.

The invention discloses a biological deodorant used for an organic fertilizer production workshop and a using method of the biological deodorant and belongs to the field of comprehensive utilization of agricultural waste recovery and environmental protection. The biological deodorant is prepared from, by weight, 20-60 parts of water, 10-20 parts of bacillus subtilis, 10-20 parts of saccharomycetes, 10-20 parts of lactic acid bacteria and 10-20 parts of molds. According to the using method, a microbial agent is dissolved in water and conveyed to the top of the workshop through a pipeline, a solution is sprayed into fine mist through a shower nozzle from the position above the organic fertilizer production workshop, the microbial agent fine mist makes full contact with smelly gas when falling in the air so that the smelly gas can be absorbed, and fast deodorization is achieved; the biological deodorant is sprayed at least two times every day, each time of spraying lasts for 15 min, the interval between every two times is at least 4 h, and the amount of the biological deodorant used every day is 1.0-1.5 kg / m<3> during maintaining. The deodorization method is easy and convenient to use, low in cost, capable of taking the deodorization effect fast and environmentally friendly.

The invention relates to a composite microbial deodorant for treating household garbage and a preparation method of the deodorant. The composite microbial deodorant is prepared from raw materials as follows: 20-30 parts of composite photosynthetic bacterium powder, 10-20 parts of Bacillus subtilis powder, 20-40 parts of composite aspergillus powder and 30-50 parts of composite yeast powder. According to the composite microbial deodorant, hydrogen sulfide, ammonia as well as strains adapted to the household garbage are screened and degraded in a targeted manner, the composite microbial deodorant comprises beneficial microbes such as Thiocapsa roseopersicina capable of efficiently degrading the hydrogen sulfide, Rhodospirillum rubrum capable of efficiently degrading fatty acid series odors and the ammonia, Aspergillus oryzae rich in enzyme systems such as proteases, cellulose and the like, Bacillus subtilis capable of quickly degrading the ammonia, Rhizopus oryzae rich in lactic acid, Saccharomyces cerevisiae for producing ethyl alcohol, Candida guilliermondii rich in aroma-producing substances and the like, the beneficial microbes grow and breed in the household garbage and have the synergistic effect, the ecological environment of the household garbage is effectively improved, and emissions of the hydrogen sulfide, the ammonia and the fatty acid series odors are greatly decreased.
