Industrial sewage is not pretreated, and the equipment behind it is all bought for nothing.
Many factories have sewage treatment equipment, and as soon as they come up, they run to the biochemical pool and MBR, but they are blocked and broken after less than half a year of operation.What's the problem?The pretreatment was not in place.For the sewage treatment equipment system, the pretreatment is the foundation, the foundation is not strong, and the floor is useless no matter how high it is.
Sewage treatment equipment
The simple structure of the grille is the core barrier of the water treatment system
The job of the grille is to stop large particles of debris. Broken cloth, plastic pieces, and thread heads go in, and the water pump impellers, pipes, and biochemical tanks behind them all suffer.Choosing a large gap is tantamount to not installing it, and choosing a small one is easy to block. It has to be determined according to the actual water quality.
In 2023. we were working on a project for a printing and dyeing factory in Weinan. The gap between the grilles they used before was too large, and all the broken cloth threads went in. The air flotation machine was blocked three times, and the maintenance cost alone was more than 20.000 yuan.Later, DIEN replaced the fine grille with a self-cleaning system, and it hasn't been cleaned once in half a year.The selection of the grille is really not cheap.
The standard adjustment tank is equipped to build a solid foundation for the entire water treatment system.
The amount of industrial sewage water fluctuates greatly.Without adjustment, the biochemical system behind it can't carry it at all.The volume of the regulating pool must be calculated accurately, and it is generally designed according to the peak flow rate of 8 to 12 hours.Many people tried to save money to make the pool smaller, but when the sewage was discharged directly, they were fined if they were found to be environmentally friendly.In my opinion, the adjustment pool is the most cost-effective in the entire pretreatment process. It doesn't cost much, but it can save the lives of all the equipment behind it.
Air flotation and precipitation process: efficient removal of grease and suspended pollutants
Oily wastewater and highly suspended solids wastewater cannot be treated by biochemical means, so the oil and suspended solids must be eliminated by physical means first.Dissolved air flotation has a good effect on emulsified oil, and the sedimentation tank has high efficiency for large particles of suspended solids.Which one to use depends on the water quality, and you can't pat your head to decide.
Sewage treatment equipment
Many people can't tell how to choose these equipment. It is recommended to look at the commonly used sewage treatment equipment and core functions. The applicable scenarios of each equipment are clearly stated in it.The pretreatment is done solidly, so that the sewage treatment equipment behind it can really run, and the water can be stable.
Our DIEN now has a complete range of sewage treatment equipment types, grille machine, regulating tank, dissolved air flotation machine, sedimentation tank, MBR membrane bioreactor, integrated equipment, sludge dewatering machine, dosing device, basically all the needs of a project can be equipped.After-sales, this piece has also been smashing resources, nationwide warranty, 24-hour response, regular inspections after each project is delivered, remote monitoring and real-time viewing of operating data, if there is a problem, you don't have to wait, and you can send someone directly.What plan does your factory use for pretreatment of this piece now?Chat in the comment area if you have any questions.
