Abstract

FIELD: waste processing and disposal.SUBSTANCE: facility relates to utilization of solid municipal wastes and is intended for separation of waste mixture into floating, suspended and sinking fractions in hydraulic separator. Separation takes place in waste water collected from a stream which has passed through trash screens and sand traps of municipal sewage treatment facilities, and the organic mixture formed during hydroseparation is directed back into the waste water stream before the primary settlers or (and) in front of the aerotanks of the urban sewage treatment facilities for intensifying the biological waste water treatment.EFFECT: use of sewage water of municipal sewage treatment facilities as a means for hydroseparation of solid municipal wastes enables to save natural water resources, refuse to purify organic hydraulic mixture, effluent from solid separator solid waste water separator, complete recovery of organic fraction of wastes, maximum use of engineering networks of urban sewage treatment facilities, create a single production and processing complex for treatment and decontamination of solid municipal wastes, treatment of waste water and utilization of sediment.1 cl, 1 dwg

Description

Для гидросепарации твердых коммунальных отходов применяют напорную воду [1,2,3].For the hydroseparation of municipal solid waste, pressure water is used [1,2,3].

Недостатками применения напорной воды для гидросепарации твердых коммунальных отходов, которые имеют IV и V классы опасности, является необходимость использования водных природных ресурсов и последующей очистки органической гидросмеси, образующейся в процессе гидросепарации.The disadvantages of using pressurized water for the hydroseparation of municipal solid waste, which have hazard classes IV and V, are the need to use natural water resources and the subsequent purification of the organic hydraulic mixture formed during the hydroseparation.

С целью устронения необходимости использования водных природных ресурсов и последующей очистки органической гидросмеси, образующейся в процессе гидросепарации, в качестве средства для гидросепарации твердых коммунальных отходов применяется сточная вода городских канализационных очистных сооружений, отобранная из потока, прошедшего через сороудерживающие решетки и песколовки, а образующаяся в процессе гидросепарации органическая гидросмесь направляется обратно в поток сточной воды перед первичными отстойниками или (и) перед аэротенками городских канализационных очистных сооружений для интенсификации биологической очистки сточной воды [4], прямое назначение которой - получение осадка и воды рыбохозяйственного качества.In order to eliminate the need to use water natural resources and the subsequent purification of the organic slurry generated during the hydroseparation process, sewage from municipal sewage treatment plants selected from the stream passing through the trash racks and sand traps is used as a means for hydroseparation of municipal solid waste hydroseparation, the organic slurry is sent back to the wastewater stream in front of the primary sumps and / or in front of the aeration tanks of the city sewage treatment plants to intensify the biological treatment of wastewater [4], the direct purpose of which is to obtain sludge and water of fishery quality.

На рис. 1 приведена технологическая схема применения сточной воды городских канализационных очистных сооружений для гидросепарации твердых коммунальных отходов: из потока сточной воды, прошедшего приемную камеру (1), сороудерживающие решетки (2) и песколовки (3), канализационной насосной станцией (4) отбирается сточная вода для подачи в гидросепаратор твердых коммунальных отходов (5), а образующаяся в процессе гидросепарации органическая гидросмесь пропускается через мацератор (6) и подается канализационной насосной станцией (7) в поток сточной воды перед первичными отстойниками (8) или (и) перед аэротенками (9) городских канализационных очистных сооружений с биологической очисткой сточных вод (10).In fig. Figure 1 shows the flow chart of the use of wastewater from municipal sewage treatment plants for the hydroseparation of municipal solid waste: from the wastewater stream passing through the receiving chamber (1), trash screens (2) and sand traps (3), and sewage pumping station (4) is used to collect wastewater for solid municipal waste (5) is supplied to the separator, and the organic slurry formed during the hydroseparation is passed through a macerator (6) and fed into the sewage pump station (7) in front of the primary settling tanks (8) or (and) in front of the aeration tanks (9) urban sewage treatment plants with biological wastewater treatment (10).

В процессе реализации технологической схемы применения сточной воды городских канализационных очистных сооружений для гидросепарации твердых коммунальных отходов сберегаются природные водные ресурсы, исчезает необходимость очистки органической гидросмеси, отходящей от гидросепаратора, происходит полная рекуперация органической фракции твердых коммунальных отходов, максимально используются инженерные сети городских канализационных очистных сооружений, создается единый производственно-технологический комплекс по обработке и обезвреживанию твердых коммунальных отходов, очистке сточных вод и утилизации осадка.In the process of implementing the technological scheme for the use of wastewater from urban sewage treatment plants for hydroseparation of municipal solid waste, natural water resources are saved, the need for purification of organic hydraulic mixtures leaving the hydroseparator disappears, the organic fraction of solid municipal waste is completely recovered, the utilities of urban sewage treatment plants are used to the maximum extent possible, a single production and technological complex is being created for the treatment and disposal of municipal solid waste, wastewater treatment and sludge disposal.
