NH3-N remover

[Wastewater] Inner Mongolia wastewater treatment spray paint wastewater treatment method: spray paint wastewater is mainly from the wet spray booth to wash the air in the spray booth operating area with water, paint and organic solvents in the air are transferred to water to form the paint wastewater. Wastewater contains a large number of paint particles, and its water quality is determined by the coatings used (mainly nitro paint, amino paint, alkyd paint and epoxy paint), solvents (such as ethanol, acetone, esters, benzenes) and additives set.

There are two forms of wastewater: one is that a part of the circulating water is discharged into wastewater and a sufficient amount of fresh water is replenished; the other is that the water is completely renewed after a certain cycle of use. Although the pollution degree of the two methods is different, the wastewater treatment is to remove dross first, then flocculate with aluminum salt, and remove most of the pigments and resins in the contained paint by precipitation or floating treatment, and part of it is surfactant. . A part of the resin and solvent remain in the treated water. The chemical oxygen demand and biochemical oxygen demand are still very high and should be further processed. The pre-treated effluent is discharged into a comprehensive wastewater collection tank, which can be treated together with other wastewater. Treatment methods include oxidation, coagulation, activated sludge treatment, and biological treatment. Spray paint wastewater treatment: 1.1 Water quantity and quality of wastewater and choice of treatment methods

An alloy car model Co., Ltd. in Shaoguan City, Guangdong Province, is a wholly-owned enterprise in Hong Kong. Inner Mongolia wastewater treatment mainly produces proportional model cars, motor toy cars and various plastic and electronic toys. The wastewater produced by the project includes spray paint wastewater, canteen wastewater and domestic sewage of employees. Among them, the spraying wastewater comes from the wastewater generated by the water curtain cabinet absorbing the spraying exhaust gas during spraying. Inner Mongolia wastewater treatment This type of wastewater contains a large amount of water-soluble paint, and the external displacement is 100t / d. And other pollutants, among which oil concentration can reach 50mg / L, CODcr can reach up to 15600mg / L, the composition is complex and the concentration is high. In addition, the employee's canteen discharges about 50 t / d of catering wastewater every day, which contains a large amount of oil, food residues and suspended solids. The domestic sewage comes from the employees' daily life processes, including showers and laundry. Sewage water quality has a large fluctuation range, which contains more organic matter and high surfactant content. The status of wastewater quality is shown in Table 1. The characteristics of the wastewater produced by this project include a large amount of domestic wastewater in addition to high-concentration spraying wastewater, so the air flotation-biochemical method was used to treat the company's comprehensive wastewater. Taking into account the characteristics of paint spray wastewater with low water volume, high concentration, and complex composition, air flotation equipment is used for pretreatment to reduce the load of subsequent treatment. In addition, the air flotation equipment is suitable for intermittent operation, and has a small footprint, convenient management and flexibility, which is suitable for the company's spray paint wastewater treatment requirements. Treatment, Inner Mongolia sewage treatment comprehensively solves several types of wastewater treatment problems generated by the company. The wastewater discharge standard after treatment is in accordance with Guangdong Province's local standard "Water Pollutant Discharge Limits (DB44 / 26-2001) second-stage first-class standard." 》

NH3-N remover

product description:

This product has a special frame-like inorganic compound as a powdery solid, which can effectively remove ammonia nitrogen from various high nitrogen-containing wastewater, and the removal efficiency of ammonia nitrogen in wastewater is more than 90%.

Instructions:

Add directly to the sedimentation tank or callback tank to fully react. Stirring or aeration is required. Inner Mongolia wastewater treatment depends on the amount of ammonia nitrogen in different wastewater. The dosage is different. Before the dosage, the optimal dosage is determined by experiments.
