Description

Technical Field

[0001] The utility model relates to the technical field of construction sewage treatment, in particular to a sewage treatment device for environmental protection at a construction site. Background Technique

[0002] The construction wastewater at the construction site mainly comes from the wastewater discharged in the daily life of construction workers at the construction site, such as kitchens, bathrooms, shower rooms, etc., as well as a small amount of wastewater discharged during various production and processing processes at the construction site. Among them, the domestic sewage is the sewage in the worker shed area, which is relatively concentrated. The construction sewage includes concrete pouring, concrete curing, vehicle washing, etc. This part of the sewage is relatively scattered. The discharged sewage must be treated to meet the standards before it can be discharged outward. Otherwise, the construction site that already pollutes the air will be further polluted due to the random discharge of sewage.

Actually, the main water tower and the auxiliary water tower can be built at the construction site, such as by bricklaying or concrete pouring. They are column-shaped and have a large water storage capacity. The inner diameter of the main water tower is significantly larger than that of the auxiliary water tower, that is, the water storage capacity of the main water tower is significantly larger than that of the auxiliary water tower. The role of the auxiliary water tower is to maintain pressure balance so that the sewage is injected from the bottom of the main water tower.
