Definitions

• the present invention provides a method for utilizing liquid wastes, especially those that are toxic and harmful and in particular those in the form of sludge, sewage, paste and liquids.
• the disadvantage of toxic and harmful waste utilization through their incineration is that large quantities of combustion products and heat energy are emitted into the atmosphere causing environmental pollution.
• the disadvantage of waste utilization using the chemical method is its high cost resulting from the need to make costly preliminary studies as wastes have various chemical compositions and the disadvantage of container storage relates to the risk of container damage during transit or as a result of the process of natural degradation of container materials. In this way the problem of utilization of wastes stored at dumping grounds is left for future generations to solve.
• the method provided by the invention uses sulphur polymer, which so far has been used as a binder for solidifying mixes for road repairs and for proofing construction materials in the form of concrete and reinforced concrete elements, concrete road surfaces, concrete pavement blocks, natural stone, wood and other similar materials and industrial solid wastes undergoing utilization.
• Sulphur polymer has also been used for proofing construction materials in the form of concrete and reinforced concrete elements, concrete road surfaces, concrete pavement blocks, natural stone, wood and other similar materials and solid industrial wastes subjected to utilization processes.
• the method is described in the Polish description of patent application no P 341996 and is characteristic in that size-reduced industrial waste, for example, in the form of fluorescent lamp breakage waste constituting up to 70% by weight is mixed with sulphur polymer and the resulting mixture is heated up to 140 °C. When the set temperature is reached the mixture is poured into metal capsules or profiling moulds. After that they are left to naturally cool down to the ambient temperature level.
• the purpose of the invention is to provide a method for utilizing liquid wastes, especially those that are toxic and harmful using sulphur polymer and mobile utilization equipment that can be used at waste generation locations.
• the method for utilizing liquid waste, in particular, those that are toxic and harmful is characteristic in that a tank made of a material that does not adhere to sulphur polymer, preferably a mobile mixer, in which there is negative pressure is filled up to from 30% to 100% of its capacity with liquid wastes, after which the tank is made to move with rotary motion or rotary-planetary motion and where at the same time the waste is preferably subjected to the action of superheated steam at a temperature between 140°C and 300°C until the waste is transformed into granulated material, after which sulphur polymer in the form of liquid or broken-up material is injected into the drum being in continuous motion where the rotary or rotary-planetary motion of the drum and the injection of sulphur polymer are stopped when the granulated waste is completely coated, after which the tank is emptied.
• An advantage of the method for utilizing liquid wastes in particular those that are toxic and harmful provided by the present invention is that it ensures correct and real waste utilization at their generation sites without the need for their transport and movement, which results in a shorter utilization cycle.
• the tank is made to move with rotary motion and the sludge inside is treated with superheated steam at 150°C until the sludge is turned into granulated material, after which sulphur polymer is injected into the tank being in continuous motion.
• the motion of the tank and the injection of sulphur polymer is stopped after the granulated waste is completely coated with sulphur polymer.
• the granulated waste with sulphur polymer coating is poured into drums or moulded into construction elements.
