8 results about "Detritus" patented technology

In biology, detritus (/dɪˈtraɪtəs/) is dead particulate organic material, as distinguished from dissolved organic material. Detritus typically includes the bodies or fragments of bodies of dead organisms, and fecal material. Detritus typically hosts communities of microorganisms that colonize and decompose, i. e., remineralize, it. In terrestrial ecosystems it is present as leaf litter and other organic matter that is intermixed with soil, which is denominated "soil organic matter". The detritus of aquatic ecosystems is organic material that is suspended in the water and accumulates in depositions on the floor of the body of water; when this floor is a seabed, such a deposition is denominated "marine snow".

A fountain structure for ecological restoration of eutrophication in a landscape lake

ActiveCN224423295UAvoid bringing inGuaranteed stabilityMicroorganismEutrophication
This utility model relates to a fountain structure for ecological restoration of eutrophication in a landscape lake, including a water inlet tank. A filter screen is installed on the inner wall of the water inlet tank. Multiple water inlets are opened on the outer surface of the water inlet tank, and multiple water inlets are opened on the upper surface of the water inlet tank. A protective box is installed on the upper surface of the water inlet tank, and a first motor is installed on the inner bottom wall of the protective box. This utility model, through a dual composite water inlet structure of water inlets and water inlets, combined with the filter screen installed on the inner wall, can intercept large particles of debris such as aquatic plants and large-diameter organic debris, avoiding the problem of device clogging. The first motor drives the rotating rod and stirring rod to rotate at high speed, and the resulting vortex can disperse algae clusters and fine organic debris in the water inlet tank, preventing them from depositing at the bottom of the water inlet tank to form an anaerobic sediment layer. This design avoids secondary pollution and also prevents deposited debris from being carried into the subsequent biological treatment stage by the water flow, ensuring the stability of the microbial degradation environment.

Method for automatically determining rock debris depth while drilling

A method for depth determination of drilled cuttings is disclosed. Tracers are injected and transported downhole along the mud flow (204, 205) and adhere to cuttings. Cuttings impregnated with tracers are detected at the surface (108) based on molecular weight, emission wavelength or radio frequency features used to encode the tracers. When a specific batch of tracers is released into the mud, the identification code identifies the depth of the drill bit. In addition to mud properties, flow rate, drilled volume and rate of penetration, formation characteristics and well specifications, detection data is transmitted to and analyzed by a tracer analysis and control engine (202). The tracer analysis and control engine (202) controls an internet of things controller (203) that adjusts parameters of a tracer injection pump (206) to enable intelligent controlled release, thereby optimizing the depth characterization process.
