System and process for de-packaging organic material and separating the organic material from the packaging. Once separated, the organic material is processed in a de-packaging machine to form an organic slurry that is directed from the de-packaging machine to an anaerobic digester. A programmed controller is provided for controlling the flow of the organic slurry to the anaerobic digester. The programmed controller is programmed to maintain the total suspended solids concentration of the organic slurry within a target range and when in the target range, the programmed controller is operative to direct the organic slurry to the anaerobic digester. If the total suspended solids concentration is outside of the target range, then the programmed controller is configured to initiate action that will bring the total suspended solids concentration of the organic slurry back within the target range.

A system and method for process water and oxide coating recovery and distribution in a direct reduction system, such as a system for producing direct reduced iron. A warm lime softener is used to remove (recover) calcium, alkalinity, and other constituents from the process water system and to produce an effluent that can be further processed and returned as makeup to the process water system. The lime softening process requires lime (or similar material) to be added to the influent, thereby increasing the calcium and pH levels until they become supersaturated and precipitate. This chemical process results in effluent that is low in calcium, alkalinity, and total suspended solids.

The invention relates to the technical field of water environment monitoring, and discloses a lake water quality multi-parameter deep learning inversion framework based on hyperspectral data, and the framework comprises the following steps: S1, data preparation and preprocessing: obtaining the hyperspectral data of lake water quality and corresponding water quality in-situ data, and preprocessing the hyperspectral data and the water quality in-situ data; s2, constructing a feature extraction and parameter inversion model which sequentially comprises a one-dimensional convolutional neural network module, a bidirectional long-short-term memory network module and a three-dimensional attention module, and inputting the preprocessed hyperspectral data into the model. According to the method, loss distribution can be dynamically optimized according to inversion requirements of different water quality parameters, the accuracy and generalization ability of simultaneous inversion of multiple parameters such as chlorophyll a, total suspended solids and transparency are remarkably improved, dependence of a traditional model on specific water body types is broken through, and the method can adapt to lake water bodies with different hydrological and optical characteristics.

The invention relates to an omnivorous fish control method and application thereof, and belongs to the technical field of water ecological restoration. The invention provides a control method for omnivorous fishes. The control method comprises the following steps: putting carnivorous fishes into a small water body containing the omnivorous fishes; the mass ratio of the carnivorous fishes to the omnivorous fishes is 1: (1-3). According to the method, carnivorous fishes with a specific proportional relation are put into a small water body containing omnivorous fishes, so that the biomass of the omnivorous fishes can be remarkably reduced, a cascade effect is triggered, the predation of the omnivorous fishes on zooplankton is reduced, the biomass of the zooplankton is increased, the predation of the zooplankton on planktonic algae is increased, and the survival rate of the zooplankton is increased. Furthermore, the disturbance of omnivorous fishes to the bottom mud can be reduced, and the total suspended matter concentration is reduced, so that the effect of repairing the water quality is achieved.

A produced water stream in a GOSP is pretreated to remove total suspended solids, emulsified oil, total organic carbon, chemical organics and inorganics, and biodegradable matter. The pretreated produced water stream is further processed to remove hydrogen sulfide gas, which is split in an electrolysis cell to produce hydrogen, sulfur, and water. Following this, bromine gas is removed. The pretreated produced water stream, after the removal of hydrogen sulfide and bromine gas, is further treated using CO2 to produce several minerals. The pretreated produced water stream, after mineral production, is desalinated to produce fresh water and a reject stream. Several valuable chemicals are produced from the reject stream. This process recovers valuable minerals and chemicals from a produced water stream in a GOSP.
