Tangshan aquaculture sewage Water treatment equipment

The main characteristics of the wastewater discharged from the farm are: high concentration of organic matter, many suspended solids, dark color, and a large number of bacteria NH3-N The concentration is very high. The pollutants in sewage mainly exist in the form of solid and dissolved carbohydrates Water meter Show a high BOD5 , CODcr , SS And chroma, the pollutants have good biodegradability, in addition, the sewage contains a large amount of N , P And other nutrients. The solid residues in the sewage are mainly organic substances. If no effective solid-liquid separation is carried out, it will bring difficulties to the subsequent treatment, increase the treatment load and affect the treatment effect. Therefore, pretreatment must be strengthened in process.

Process of aquaculture sewage treatment equipment:

Aquaculture wastewater treatment process:

According to the quality of aquaculture wastewater and the discharge standard, the commonly used aquaculture wastewater treatment process is determined as ;

Pretreatment Hydrolysis acidification tank Anoxic tank Aerobic tank Secondary sedimentation tank Disinfection tank

The breeding wastewater is treated by septic tank, primary sedimentation tank, regulating tank, hydrolysis acidification tank, anoxic tank, contact oxidation tank, secondary sedimentation tank, disinfection tank and other processes, and the effluent reaches the Discharge Standard of Pollutants for Livestock and Poultry Breeding Industry (GB18596-2001) The treated water can be directly discharged or reused according to the discharge standard of water pollutants required in.

Introduction to aquaculture sewage treatment equipment:

The aquaculture sewage treatment is composed of a secondary tank, which is made of steel structure and is buried shallowly. The steel structure pool adopts the first interpenetrating network in China Anticorrosive coating Corrosion protection. It is a kind of rubber network Plastic net The complex penetrates each other to form an interpenetrating network polymer, which can resist acid, alkali, salt, gasoline, kerosene, aging, abrasion, rust and rust. The equipment is generally painted with coating After that, the anti-corrosion life can reach twelve More than years.

Features of aquaculture sewage treatment equipment:

one The process of integrated sewage treatment equipment is mature, and the effluent reaches the standard stably;

two The integrated sewage treatment equipment has reasonable structure, low cost and stable effluent;

three The integrated sewage treatment equipment has low operation cost, simple installation and easy maintenance;

four Wide application scope of equipment;

five , flexible placement, underground, semi buried and outdoor;

six Good maneuverability, high modularization, and can be used in combination;

seven , automatic disinfection system, effluent up to standard;

Case of aquaculture sewage treatment equipment project:

Shaoguan Muke Industrial Co., Ltd. is a large-scale industrialized breeding pig farm. At present, it is a production base for pollution-free agricultural products of the Ministry of Agriculture, a live pig export registration farm, a provincial original pig farm, a provincial key pig farm, and a key agricultural leading enterprise in Shaoguan. The pig farm is located in the modern agricultural demonstration park in northern Guangdong planned by Shaoguan City —— Fengwan Town, Qujiang District, covering an area of more than 1000 mu, has built five standard modern production lines, with annual sales reaching six Ten thousand. The company has complete living facilities, including basketball court, badminton court and Kara OK Room, dining hall and other living and entertainment facilities.

Water quality characteristics of wastewater: high concentration of organic matter, many suspended solids, dark color, and a large number of bacteria, which are caused by a large number of animal feces NH3-N The concentration is very high. The pollutants in the wastewater mainly exist in the form of solid and dissolved carbohydrates, which makes the wastewater show a high level of BOD5 , CODcr , SS And chroma, the pollutants have good biodegradability, in addition, the wastewater contains a large amount of N , P And other nutrients. The solid residues in the wastewater are mainly organic substances. If no effective solid-liquid separation is carried out, it will bring difficulties to the subsequent treatment, increase the treatment load, and affect the treatment effect. Therefore, pretreatment must be strengthened in the process 。
