experiment example
[0051] Experimental example: 80 households in a certain village were subjected to the separate collection and treatment of black water and gray water as an example. The system of the present invention was used for processing. Under normal operating conditions, the inflow and outflow water quality of black water and gray water sampling is shown in the table below Show.
[0052]
[0053] It can be seen from the above table that the ash effluent quality of the present invention fully meets the first-level standard in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" GB18918-2002, and the black water reaches the second-level standard. It is completely possible to reuse the reclaimed water.

The invention discloses a rural black and grey water collection, treatment and resource utilization system. The system comprises a household miscellaneous drainage collecting pipe, a household toiletflushing water collecting pipe and a breeding excrement water collecting pipe, and is characterized in that the miscellaneous drainage collecting pipe is connected with the upper part of an oil-separating deslagging well, the bottom of the oil-separating deslagging well is connected with a grey water treater through a grey water main pipe, and reclaimed water is recycled after water in the grey water treater is treated, the household toilet flushing water collecting pipe is connected with a black water treater through a black water main pipe, the black water treater is connected with a black water advanced treatment device through a pipeline, the breeding excrement water collecting pipe is directly connected with the black water advanced treatment device, and liquid treated by the black water advanced treatment device is output through a submersible pump to be used as fertilizer. The construction period is short, and civil engineering investment is saved by adopting the carbon steel anti-corrosion square tank body or the glass fiber reinforced plastic tank body.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a rural black and gray water collection, treatment and resource utilization system. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the total amount of industrial and agricultural production, domestic water consumption and sewage discharge continues to increase. Especially in towns and rural areas, a large amount of sewage is produced every year. Due to the low technical level and management level of personnel, the sewage treatment rate in townships and rural areas is low at this stage. Today, when people generally begin to pay attention to environmental protection, it is required to seek economical, efficient, energy-saving, and easy-to-operate and manage sewage treatment solutions under the requirements of environmental protection on the basis of full resource utilization. [0003] The treatmen...
