Example Embodiment

[0026] A ground filter device for domestic sewage treatment during construction, comprising a filter tube, one end of the filter tube is provided with a water inlet pipe, and the other end is provided with a water outlet tube, the filter tube is provided with four layers of filtering layers, the four layers of filtering from the design From the end of the water inlet pipe to the end of the water outlet pipe, there are gravel, ceramsite, fine sand and sponge in sequence. The filter tube is a PVC plastic tube. The gravel, ceramsite, fine sand and sponge are all installed in the PVC plastic tube. When filling various materials, the sponge, Fine sand, ceramsite, gravel. The sponge has a cylindrical structure with an outer diameter equal to the inner diameter of the filter tube. The water inlet pipe and the water outlet pipe are respectively connected with the filter pipe through a variable diameter straight joint.

Abstract

The invention relates to a building construction process domestic sewage treatment ground filtering device and a filtering method. The device comprises a filtering pipe, a water inlet pipe is arranged at one end of the filtering pipe, a water outlet pipe is arranged at the other end of the filtering pipe, and four filtering layers are arranged in the filtering pipe and are sequentially gravel, ceramsite, fine sand and sponge from one end of the water inlet pipe to one end of the water outlet pipe. Domestic sewage primarily treated by a septic tank is secondarily filtered by the four filtering layers including the gravel, the ceramsite, the fine sand and the sponge, water quality is further improved to meet secondary pollution exhaust criteria, and produced sewage in the whole engineering construction period is controlled, so that surrounding environments are protected.

Description

Technical field [0001] The invention relates to a domestic sewage treatment technology, in particular to a ground filtering device and a filtering method for domestic sewage treatment during construction. Background technique [0002] Judging from the current situation, during the construction process of the construction project, most of the local municipal sewage and rainwater systems are imperfect. In addition, the construction unit and the construction unit pay little attention to it, resulting in a large amount of construction wastewater, Environmental pollution sources such as sewage directly damage the local surface water quality and ecological environment. [0003] In view of the above situation: the existing sewage treatment in the construction process generally adopts the septic tank precipitation fermentation technology. Use the sedimentation chamber and the corruption chamber inside the septic tank to remove the suspended organic matter in the domestic sewage. [0004] T...
