Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Please refer to figure 1 and figure 2 ,in, figure 1 A schematic structural view of a preferred embodiment of the treatment method for urban underground construction yellow muddy water provided by the invention;

[0025] figure 2 It is a floor plan of the equipment of the present invention. The processing method of urban underground construction yellow muddy water comprises the following steps:

[0026] S1: the water inlet pump 2 extracts the yellow muddy water in the mud collection tank of the construction site through the water inlet pipe 7, and lifts it into the reaction tank through the lift pump 2;

[0027] S2: Add the filter aid and sedimentation aid in the filter aid and sedimentation aid dosing tank to the inside of the reaction tank 1 through the first dosing pump 9, so that the filter aid and sedimentation aid and the yellow muddy...

Abstract

The invention provides a method for treating urban underground construction yellow muddy water. The method for treating urban underground construction yellow muddy water comprises the following steps:S1, a water feeding pump draws out the yellow muddy water in a mud collecting tank at a construction site through a water inlet pipe, and the yellow muddy water is lifted into a reaction tank througha lift pump; S2, a first dosing pump adds a filtering and settling aid inside a filtering and settling aid dosing barrel into a reaction barrel, and the filtering and settling aid and the yellow muddy water are fully mixed to form muddy water with a high density; and S3, a second dosing pump adds a PAM agent in a PAM dosing barrel into the reaction tank. The method for treating urban undergroundconstruction yellow muddy water can completely remove yellow mud and colloidal substances in the yellow muddy water in the construction site, and allows the effluent water to be clear, the SS contentis less than 10 mg / L, and the visible depth is 2 m or more; and the method has the advantages of integration of devices, high intensive degree, high sludge dewatering efficiency, and low water contentof the generated sludge.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for treating yellow muddy water in urban underground construction. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] The yellow muddy water produced by existing pile drivers on the construction site, with the increasingly stringent environmental protection requirements, the river chief system has been implemented in v...
