Which is a good seller of sewage sludge repair and washing equipment

Ditch sludge has the characteristics of multiple points, wide coverage, dispersion, irregular timing, and small quantity, and in China, it is also mixed with a large amount of household waste, bark, bricks, and other debris. Untreated sewage sludge not only becomes an important source of pollution,At the same time, it also seriously affects the normal operation of drainage facilities,If not resolved promptly and properly,It will inevitably become a hidden danger that damages the urban environment.Ditch sludge soil remediation and washing equipmentIt is specially developed by Desen Environment based on the characteristics of sewage sludge, and has the advantages of fast remediation effect, short cycle, and low cost, which is widely used.

Ditch sludge soil remediation and washing equipmentThe workflow for treating sewage sludge mainly consists of crushing and feeding, scrubbing, grading and decoration, high-efficiency washing, cyclone dewatering, concentration and pressure filtration, water treatment and other steps. 1、 The secondary screening system will screen out solid particles larger than 2 mm, purify them, and comprehensively utilize them.2mmThe following sand particles are soaked in chemicals and washed with enhanced efficiency to remove residual harmful substances. Among them, greater than0.25mmAfter undergoing three-stage cyclone dehydration, the solid phase is screened out and purified for comprehensive utilization.0.25mmThe following fine sand particles are filtered by plate and frame, and a portion is converted into0.075 mmThe following particles are converted into mud cake after solid-liquid separation.

The heavy metal content control value of the equipment after sludge remediation meets the requirements of GB 36600. The sludge formed by the remaining solid phase after pressure filtration meets the requirements after treatmentGB 18598The required indicators. The wastewater formed can be reused after treatment, with a portion concentrated to form a washing solution and another portion forming a recyclable water. The solid content in the treated liquid does not exceed1%The water quality meets the requirementsGB 8978The relevant provisions of the third level standards for medium and second class pollutants shall be implemented. It can effectively achieve the reduction, harmlessness, and resource utilization of sewage sludge.
