In the concrete production process, the equipment cleaning and the vehicle cleaning process will produce a large amount of sewage wastewater. A great waste of resources at the same time, direct emissions can also cause great harm to the environment.
Therefore, the sewage treatment system in concrete production will achieve 100% recovery of its wastewater, to meet the zero discharge standard of sewage.
Sewage treatment and reconstruction system mainly includes concrete transport fleet unloading watery trough, sandstone separator equipment, sewage sedimentation tank, sewage pool mixer, clarification tank, conveyor pump, filter press and so on. There are a total of four sewage ponds and 3 clarification pools in the conventional system. 4 sewage ponds are equipped with surface guardrails and mixers. and 1th pool, 2nd pool, 3rd sewage pool with mud pump, 2nd and 4th pool design with liquid level meter; 3 clarifying pool you each have a sewage pump.
The uniform movement of the mixer cycle in the pool ensures the uniformity of water quality in the pool. The various pools in the sewage treatment system need to be arranged in a certain order, the bottom of the pool has overflow tubes connected to each other, the upper part of the pump connected to each other. When the amount of water in the pool is insufficient, the pump can be used to transport recharge, to maintain the stability of water.
If the amount of water in the pool is long, it will flow back through the overflow pipe provided by the pool and the water quality can be clarified during the reflux process. In the concrete mixing station and the design of a water tank and sewage pool connection, the collection of rainwater flow into the pool to ensure the cleanliness of the station at the same time also reduce operating costs.
The main station and the vehicle cleaning system are equipped with special flow grooves to produce sewage diversion to the sewage pool for unified treatment. Through the guidance and transformation of the whole drainage in the concrete mixing station, the sewage in the mixing station is not outflow, and the treated sewage is tested and directly supplied to the mixing station for use and vehicle cleaning, and the waste residue produced can also be used as the added aggregate. To achieve zero discharge of sewage treatment.
