摘要

1. Station for biological wastewater treatment, including a device for aerobic stabilization and a device for compaction of excess sludge, characterized in that both devices are a single rectangular reservoir, forming at least one combined mineralizer-sealant, and the mineralizer is made in in the form of a corridor-type aerated tank operating in displacement mode, and the seal is made in the form of a horizontal settler separated from the mineralizer by a partition with an opening that communicates the seal with the outlet of the mineralizer, while the mineralizer is equipped along its entire length with a fine-bubble aeration system with a wide aerated strip, and the seal contains pits equipped with a device for removing compacted sludge from the compactor with the possibility of returning part of it to the inlet of the mineralizer. 2. The station according to claim 1, characterized in that it contains channels of excess and compacted sludge, separated by a partition having a window with a shield gate, while the inlet of the mineralizer is in communication with the channel of excess sludge, and the outlet of the sealant is in communication with the channel of compacted sludge. The station according to claim 2, characterized in that the device for removing compacted sludge from the compactor includes airlifts for pumping compacted sludge from the pits and at least one tray for supplying compacted sludge from the pits to the channel of the compacted sludge. The station according to claim 3, characterized in that the tray is installed between the rows of pits above them. A station according to any one of claims 1-4, characterized in that the total length of the mineralizer exceeds the width of its corridor by at least 30 times. Station according to any one of claims 1-5, characterized in that the mineralization
