Domestic wastewater hydrolysis tank

Abstract

The present invention relates to a domestic wastewater hydrolysis tank including a tank body, an inlet pipe, an outlet pipe and a barrier plate, the inlet pipe is arranged on one side of the tank body, one end of the inlet pipe is located outside the tank body and connected with a user, and the other end of the inlet pipe vertically extends into water in the interior of the tank body to form liquid seal; the outlet pipe is arranged on the other side of the tank body, one end of the outlet pipe vertically extends into the water in the interior of the tank body, the other end of the outlet pipe extends to the outer side of the tank body and is connected with subsequent processing equipment; the barrier plate is arranged in the tank body, and near the outlet pipe, the upper end of the barrier plate is higher than liquid level, and a gap is between the lower end of the barrier plate and the bottom surface of the tank body. The domestic wastewater hydrolysis tank is scientific in design, rational in structure and reliable in operation, can be used for pretreating the wastewater to separate contaminants, impurities and the like in the domestic wastewater so as to reduce subsequent wastewater treatment amount, improve wastewater treatment effect, and reduce treatment costs.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage hydrolysis tank. Background technique [0002] Due to the low population density in rural areas, the scattered residence of farmers, the small amount of sewage in some areas, and the large differences in terrain, lack of sewage collection and transportation facilities, it is difficult to collect domestic sewage in a centralized manner, especially in small towns, there are financial constraints on the construction of public sewer facilities Difficult, although oxidation ditch process, A / O process, A 2 / O process, AB and SBR processes have remarkable effects, but these centralized treatment methods require expensive sewage collection pipe network construction costs, not only large investment, but also complex operation management and high maintenance costs. Difficult to implement in rural areas. Therefore, the centralized processing model will be diffic...

Problems solved by technology

[0004] Although the effect of the device is very good in use, the direct discharge of sewage into the device will relatively increase the processing capacity of the device and increase the processing load
