A method for processing liquid manure 1, in particular cattle manure, comprising: supplying the liquid manure 1, separating 2 the solid parts 14 in the manure from the liquid part 3, treatment of the liquid part 3 by: adding Magnesium Chloride 5 to convert Phosphates in the liquid part into Struvite, and inserting air 6, increasing the pH level in the liquid Struvite 7 by Lime injection 9 to convert the Ammonium into Ammonia, adding Hydrochloric acid 12 to convert Ammonia into Ammonium Chloride, separating Phosphor and Nitrogen containing components from the resulting liquid 18 by reverse Osmose 17, mixing 13 the separated Phosphor and Nitrogen containing components 16 with the precipitate Struvite 15 and solid parts 14 resulting from the separation process 2 to get fertilizer 22, neutralizing 20 the remaining liquid 19 to get clean water 21.

The present application relates to a field of excrement treatment equipment in particular, relates to an ultra-high temperature excrement solid-liquid separation extrusion sterilization integrated machine. It includes a solid-liquid separator, a workbench and an extrusion sterilization device. The solid-liquid separator is disposed on the workbench. The extrusion sterilization device includes an extrusion sterilization motor, an extrusion feeding assembly, a receiving pipe, a receiving box and a dehydrating cage.

A water storage tank includes a water storage tank body; the water storage tank body is defined with a liquid storage chamber for storing a liquid and for receiving a water pump, and an opening communicating with the liquid storage chamber; an open groove for allowing a power line to pass through is formed in the water storage tank body; and the open groove penetrates through an end edge of the water storage tank body close to the opening. Since the power line can be led out from the liquid storage chamber by directly clamping into the open groove from top to bottom, the power line is arranged conveniently and there is no need to provide a wiring box or a wiring groove for the power line.

The present disclosure provides a means to remove oxidative compounds such as free halogen and chloramines from a liquid, while also providing components with antimicrobial properties in order to combat biofouling and the shedding of pathogens into liquids. In particular, methods of removing an oxidative compound from a liquid in which the liquid is contacted with one or more polymeric beads. As described herein, the oxidative compound binds to the polymeric bead and is removed from the liquid.

[Problem]

To provide a microorganism deodorizing device capable of sufficiently exhibiting a decomposition-deodorization function while suppressing an increase in manufacturing cost, even in a large-scale device including a large-sized deodorizing tank.

[Solution]

A deodorizing tank 1 of a microorganism deodorizing device 1A forms an airflow passage 20 through which air passes from a chamber unit 3 to an opening portion 19; and the airflow passage 20 is provided with a deodorizing unit 5 in which a foam material 17 is filled, a ventilation resistance layer 4 arranged close to or adjacent to the deodorizing unit 5 and configured to increase ventilation resistance of the air flowing through the airflow passage 20, and a chamber unit 3 arranged close to or adjacent to the deodorizing unit 5 and/or the ventilation resistance layer 4 as a chamber which temporarily stores the air fed to the deodorizing tank 1; and the air is fed to the deodorizing unit 5 in a state of being spread in the chamber unit 3 over a substantially entire surface of the deodorizing unit 5 as a result of that the ventilation resistance of flow of the air flowing through the airflow passage 20 is increased by the ventilation resistance layer 4.

The invention relates to a continuous process for treating organic waste taking place in a plant, said process for treating organic waste comprising a process of anaerobic digestion of a first part of said waste, which takes place in at least one digestion chamber, and a process of aerobic composting of a second part of said waste, which takes place in at least one composting chamber, the process for treating organic waste comprising the steps of:—collecting digestate and biogas at the end of said anaerobic digestion process,—collecting compost and humic percolate at the end of said aerobic composting process,—feeding at least part of said digestate
