Abstract

1. Способ биологической очистки сточных вод, согласно которому осуществляют подачу сточных вод посредством патрубка подачи в аэрационную камеру с направляющей трубой, в которую посредством диффузора аэратора подают воздух для смешивания его со сточной водой, осажденный при обработке активный ил удаляют посредством стояка для откачки избыточного активного ила, а очищенную воду самотеком удаляют через выходной патрубок водослива, отличающийся тем, что аэрационную камеру выполняют с глухим днищем, а диффузор аэратора размещают вблизи глухого днища, направляющую трубу выполняют в форме обратного конуса по отношению к нижней части аэрационной камеры, нижний торец направляющей трубы размещают над глухим днищем аэрационной камеры, при этом осуществляют предварительное разделение твердых включений от мелких фракций, после которого в зону разделения подают воздух посредством диффузора аэратора, где смешивают его с поступившей сточной водой, дополнительно измельчают твердые включения до фракции активного ила, который затем направляют в отстойник, используют его повторно, посредством чего улучшают очистку воды, освобождая ее от вновь поступивших биологических включений, причем перед сбросом в грунт очищенной воде проводят доочистку на песчано-щебеночном фильтре.2. Способ по п.1, отличающийся тем, что песчано-щебеночный фильтр выполняют в виде фильтрационного колодца, или в виде кассеты, или в виде траншеи.3. Способ по п.1, отличающийся тем, что предварительное разделение твердых включений от мелких фракций осуществляют с помощью полимерной загрузки для прикрепленного активного ила, посредством которой образ�1. A method for biological wastewater treatment, according to which wastewater is supplied through a supply pipe to an aeration chamber with a guide pipe, into which air is supplied through an aerator diffuser to mix it with wastewater, activated sludge precipitated during treatment is removed through a riser for pumping out excess active sludge, and the purified water is removed by gravity through the outlet of the weir, characterized in that the aeration chamber is made with a blank bottom, and the diffuser of the aerator is placed near the blank bottom, the guide pipe is made in the form of a reverse cone in relation to the lower part of the aeration chamber, the lower end of the guide pipe placed above the blank bottom of the aeration chamber, while preliminary separation of solid inclusions from small fractions is carried out, after which air is supplied to the separation zone through the diffuser of the aerator, where it is mixed with the incoming waste water, solid inclusions are additionally crushed to a fraction activated sludge, which is then sent to the settler, is reused, whereby the water purification is improved, freeing it from newly received biological inclusions, and before the purified water is discharged into the ground, additional purification is carried out on a sand-gravel filter. 2. The method according to claim 1, characterized in that the sand-crushed stone filter is made in the form of a filtration well, or in the form of a cassette, or in the form of a trench. The method according to claim 1, characterized in that the preliminary separation of solid inclusions from fines is carried out using a polymer load for attached activated sludge, through which the sample

Claims

1. The method of biological wastewater treatment, according to which the wastewater is supplied through a supply pipe to the aeration chamber with a guide pipe into which air is supplied by means of an aerator diffuser to mix it with wastewater, the activated sludge deposited during processing is removed by a riser to pump out excess active sludge, and purified water by gravity is removed through the outlet of the spillway, characterized in that the aeration chamber is performed with a blank bottom, and the aerator diffuser is placed near the hl At the same time, the guide tube is made in the form of a cone in relation to the lower part of the aeration chamber, the lower end of the guide tube is placed above the blank bottom of the aeration chamber, while preliminary separation of solid inclusions from fine fractions is carried out, after which air is supplied to the separation zone by means of an aerator diffuser where it is mixed with incoming wastewater, solid inclusions are additionally crushed to a fraction of activated sludge, which is then sent to the sump, it is reused, osredstvom which improve water purification, freeing it from the newly received biological impurities, wherein prior to discharge into the ground purified water is conducted to additional cleaning filter sand and macadam.

2. The method according to claim 1, characterized in that the sand-gravel filter is made in the form of a filtration well, or in the form of a cartridge, or in the form of a trench.

3. The method according to claim 1, characterized in that the preliminary separation of solid inclusions from fine fractions is carried out using a polymer charge for attached activated sludge, through which form a biological filter for pre-treatment.
