Wastewater treatment device for constructional engineering

Abstract

The invention relates to the field of wastewater treatment, in particular to a wastewater treatment device for constructional engineering. The device comprises a wastewater treatment tank arranged on a bracket, a top plate is arranged at the top of the wastewater treatment tank, a liquid inlet pipeline is arranged at the upper half part of the side wall of the wastewater treatment tank, and a blanking channel is arranged at the bottom of the wastewater treatment tank; a crushing device is further arranged at a liquid inlet pipe opening of the liquid inlet pipeline, the multi-stage screening device comprises a first-stage screening mechanism, a second-stage screening mechanism and a supporting mechanism, and a water purification tank is further arranged on the wastewater treatment box; one end, far away from the blanking channel, of the second-stage screening mechanism is further provided with a garbage storage box used for storing gravel and scrap iron in a layered manner. Through cooperation of the first-stage screening mechanism, the second-stage screening mechanism and the supporting mechanism, the filtering treatment of wastewater is realized, so that the condition that meshes of a sieve plate in the prior art are blocked during water filtration is avoided, and the filtering effect is improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a wastewater treatment device for construction engineering. 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 physical objects at designated locations. A lot of waste water will be generated in the waste water, and the direct discharge of sewage will cause environmental pollution and waste water resources. When the existing construction project waste water treatment device treats the waste water, it is not easy to crush the solid impurities such as mud, sand, and garbage in the waste water. , and the pulverized solid impurities are difficult to discharge to the outside world, which will easily cause the solid impurities to block the purificat...

Problems solved by technology

[0004] According to the above-mentioned patent, the patent sieves water, sand and iron filings through the vibration of the sieve plate, and then pushes the sand out of the sieve plate. However, when the sand is pushed out from the sieve plate, it will cause the sieve plate to The clogging of the sieve holes on the screen will easily affect the subsequent filtration of wastewater. Therefore, for this problem, there is a need for a wastewater filtration device that can ensure that the sieve plate does not clog during the process of filtering wastewater.
