Problems solved by technology

[0006] However, although the single-household treatment device can treat domestic sewage well and is almost unattended, the device is too expensive after all. If one household is installed in rural areas, the financial pressure will inevitably be great. Due to the limitations of large differences, the construction of pipe network is not only expensive but also very difficult, and it is almost impossible to promote. Therefore, it is very important to develop a processing model suitable for my country's national conditions

Embodiment 1

[0054] Joint use of domestic sewage by 15 households: such as image 3 As shown, fifteen hydrolysis tanks (1200X800X1200) and two new-type purification tanks (2100X1500X1700) are connected in series, all aeration is adopted in the first, second and third-level areas. The air pump power of the first new-type purification tank is 200W, and the gas flow rate is 200L / min, the power of the second unit is 150W, the gas flow rate is 150L / min, and the power consumption per ton of water is 0.28 yuan.

[0055] Such as Figure 4 As shown, the water samples in each area from right to left are the water from the hydrolysis tank, the first and third levels of the first new type of purification tank, the first and third levels of the second new type of purification tank, and the effluent from the disinfection tank. From the first-level area of ​​the first new purification tank in the picture, it can be seen that the sewage entering the tank is particularly turbid, with a high concentration...

Embodiment 2

[0057] Combined use of domestic sewage in ten buildings and farmhouses: such as Figure 5 As shown, two hydrolysis tanks (2100X1500X1700) are respectively connected to the domestic sewage of five households from top to bottom, and two new purification tanks (2100X1500X1700) are connected in series, and the sewage treated by the two hydrolysis tanks is concentrated into the new series of purification tanks. The first, second, and third-level areas are all aerated. The air pump power of the first new purification tank is 150W, the gas flow rate is 150L / min, the power of the second one is 120W, the gas flow rate is 120L / min, and the power consumption per ton of water is 0.33 Yuan.

[0058] Changing the amount of aeration can increase the number of processing households. When the new purification tank is fully aerated and the power of the air pump is 200W, the number of processing households can be increased to 20. Under the same conditions, the new purification tanks used in ser...

Embodiment 3

[0061] Such as Figure 7 As shown, the Wucheng branch of Shandong Shuangyi Group Co., Ltd. has 250 employees, a staff canteen, and a daily discharge of domestic sewage of 18 tons. The original three-grid hydrolysis tank of 6 cubic meters will use two sets according to the daily processing capacity. The new purification tank and septic tank series process, as shown in the figure. The first, second, and third-level regional aeration is adopted. The air pump power of the first new purification tank is 200W, the gas flow rate is 200L / min, the power of the second one is 150W, the gas flow rate is 150L / min, and the power consumption per ton of water is 0.24 Yuan.

[0062] Such as Figure 8 As shown, the water samples in each area from right to left are the effluent of the hydrolysis tank, the first and third levels of the first new type of purification tank, the third level of the second new type of purification tank, and the effluent. From the water outlet state of the hydrolysi...

Abstract

The invention relates to a device adopting series-parallel connection combination of multi-family domestic sewage hydrolytic tanks and multiple treatment devices. The device comprises hydrolytic tanks and treatment devices, wherein the number of the hydrolytic tanks and the number of the treatment devices each are one or more, the hydrolytic tanks and the treatment devices are connected; and when multiple treatment devices are arranged, the treatment devices are arranged in series and in parallel and are purification tanks. The device adopting series-parallel connection combination of the multi-family domestic sewage hydrolytic tanks and the multiple treatment devices is scientific in design, reasonable in structure and reliable in operation; the treatment devices are improved according to the treatment status of rural household life sewage, so that a technology is developed; the maximum advantage is in-situ treatment, a complex pipe network is not needed, the device is not subject to the influence of seasonal temperature difference due to an underground mode, the device is unattended and is longer than 30 years in service life, discharged water reaches level 1 of national discharging standard, can be used as water for irrigation and lawns and the like, and further can be directly discharged into the nature.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a series-parallel combination equipment of a multi-household domestic sewage hydrolysis tank and a plurality of treatment devices. Background technique [0002] The rural population in my country was larger than the urban population in 2012, about 640 million people, and the BOD load discharged to the environment per person per day was 40g / person·day, and the total BOD load discharged to the environment by the agricultural population alone exceeded 1,000 per year. Three million tons, seriously polluting the quality of rural water bodies. The development of small-scale and high-efficiency domestic sewage purification tanks can solve the problem of centralized treatment and implement in-situ treatment, which can not only solve the pollution problem of rural domestic sewage from the source, but also promote the effective implementation of tap water in rural areas and improve...
