Description
Изобретение относитс к способалг очистки сточных вод с нримснеиием бпофнльтров, работающих в аэробных услови х.The invention relates to a method for the treatment of wastewater with the implementation of aerobic conditions.
Известный способ очистки сточных вод на биофильтре с загрузкой из доменного шлака не обеснечивает высокую эффективность процесса из-за недостаточно высокой удельной иоверхиости шлака. Кроме того, вследствие его невысокой иористости возможно заиливанне дренажных устройств.The known method of sewage treatment on the biofilter with loading from the blast furnace slag does not provide for the high efficiency of the process due to the insufficiently high specificity of the slag. In addition, due to its low yawliness, it is possible that the drainage devices are silted down.
С целью инте1 снфикацни процесса, а также расширени ассортимента матернала загрузки , нредложено в качестве загрузки использовать термозит (1нлаковую пемзу). Термозит вл етс продуктом обработки расплава доменного шлака стру ми воды н нара нли воздухом . Он имеет больигую удельную поверхность , малый объемиый вес (0,789 кг/м), более высокую пористость и газонропицаемость, чем необработанный доменный шлак, что увеличнвает площадь контакта воды п колпчество участвующих в очистке микроорганизмов, и, следовательно, привод1гг к иптенсификацпп процесса. Кроме доменного шлака, в качестве загрузки биофплЕ тров примен ют кокс, каменноугольный шлак, песчаннк, гранитный щебень, гальку н др.For the purpose of introducing the process, as well as expanding the range of material loading, it is proposed to use termozit (1lak pumice) as a load. Termite is a product of melt processing of blast furnace slag with water or air. It has a large specific surface area, a small volume weight (0.789 kg / m), a higher porosity and gas permeability than the raw blast furnace slag, which increases the contact area of water and the number of microorganisms involved in the cleaning, and, consequently, leads to the intensity of the process. In addition to blast-furnace slag, coke, coal slag, sandstone, crushed granite, pebbles and other coke are used as bioflater loading.
Термознт расншр ет нмеюшнйс ассортимент материалов, используемых в биофильтрах . Он долговечен, имеет высокую механическую прочность, устойчив к действию кислот н щелочей, дешев, что в совокунностн обеснечнвает экономню средств на оч 1стку.Thermal research expands the range of materials used in biofilters. It is durable, has high mechanical strength, is resistant to acids and alkalis, and is cheap, which, in general, saves money for very little money.

After passing the biofilter, the contained BeHiecTB permutations in the water are up to 55.3 / Ns / -, Nils - up to 10 l / s /, 7, water transparency 10. The quality is 15years after the bpo (| devices does not occur.
