The invention relates to a static aerobic fermentation drying tower and an application and belongs to the technical fields of agricultural organic waste resource utilization and environmental protection. The invention solves the problems of exposed production, easily caused secondary pollution, low resource utilization, large volume of organic raw materials and inconvenient carrying and the like of the existing composting technology. The invention comprises a fermentation drying tower which is built at a required minimum driving height of a forklift and a tower-type sealing fermentation and internal ventilation structure, and by utilizing accumulated temperature effect generated by whole fermentation and backflow circulation of high-temperature and high-moisture fermentation heat, static fermentation, drying and microorganism multiplication culture are finished once. By utilizing the fermentation heat, the moisture content of dry materials can reach below 25 percent, and simultaneously, the medium-temperature fermentation time is prolonged, the fermentation cycle is shortened, and active substances are kept to the greatest extent. The fermentation drying tower and the civil work of a tower body are integrated, thus saving the investment and being durable, and the application of a normal loading machine has high efficiency and low production cost. The product is high-quality organic fertilizer or bio-organic fertilizer if microorganisms with specific functions are added.

It makes and fixes model according to the needed decorating sculpt, it sets reinforcing steel bar which is used as the framework of overburden, the niters are confected into concrete, the concrete are filled into model, demoulds it when it reaches the fixed intensity, then carves it according to the quality of natural stone.

The invention belongs to the technical field of petrochemical industry, and particularly relates to an oily sludge cleaning method. The oily sludge cleaning method comprises the following steps: collecting oily sludge, carrying out crush treatment on the oily sludge, and then filtering by using a vibrating screen; adding water and a first cleaning agent into the filtered oily sludge for diluting to obtain mixed oily sludge; sending the mixed oily sludge into a micro-nano bubble oily sludge cleaning integrated device for cleaning. In the oily sludge cleaning method, micro-nano bubbles in a cyclone cleaning tank can quickly and efficiently clean the oily sludge in the presence of a small amount of cleaning agent, so that the cleaning cost is reduced; by the oily sludge cleaning method provided by the invention, the cleaning residence time is only 5-30min, the dosage of the cleaning agent is 1 / 10-1 / 3 of that in the conventional method, and the comprehensive energy consumption is 1 / 5-1 / 2 of that in the conventional method; the oily sludge cleaning method is especially suitable for cleaning treatment of open-air oily sludge.

The invention discloses a method for jointly treating acid mine wastewater by using organic matter and carbonate rock. A first-stage pretreatment area (1) is a container which is divided into left and right parts, the bottoms of the left and right parts are communicated, one side of the container is filled with organic matter filler, and the other side of the container is filled with carbonate rock filler; wastewater firstly contacts with the organic matter, the principle that the growth of aerobic microorganisms needs to consume dissolved oxygen is used, so after acid mine wastewater passes through the organic matter, the dissolved oxygen in the wastewater is removed, and an oxygen-free condition is formed; the carbonate rock is used to adjust pH under the oxygen-free condition, so the voids of the filler can be prevented from being blocked by the Fe(OH)3flocs rapidly generated in a reaction area; water flows from the first-stage pretreatment area (1) to enter multistage tandem reaction areas (2), each reaction area (2) is the same as the first-stage pretreatment area (1) in the structure and the contents, wastewater is re-aerated in the process that the wastewater enters a sedimentation tank from the carbonate rock reaction area through a natural drop way. The method is good in effect, low in investment and low in the cost of wastewater treatment.
