Embodiment 1

[0022] The sewage treatment agent specially used for high ammonia nitrogen content in this embodiment is composed of the following raw materials in parts by weight: 2 parts of zeolite powder, 1 part of persimmon tannin, 2 parts of diatomaceous earth and 0.2 part of grape seed tannin.

[0023] When the influent ammonia nitrogen>100mg / L, the dosage of sewage treatment agent is 2kg / ton of sewage; when 50mg / L≤influent ammonia nitrogen≤100mg / L, the dosage of sewage treatment agent is 1kg / ton of sewage; When the water ammonia nitrogen is less than 50mg / L, the dosage of sewage treatment agent is 0.4kg / ton of sewage.

Embodiment 2

[0025] The sewage treatment agent specially used for high ammonia nitrogen content in this embodiment is composed of the following raw materials in parts by weight: 5 parts of zeolite powder, 1.5 parts of persimmon tannin, 3 parts of diatomaceous earth and 0.5 part of grape seed tannin.

[0026] When the influent ammonia nitrogen>100mg / L, the dosage of sewage treatment agent is 3kg / ton of sewage; when 50mg / L≤influent ammonia nitrogen≤100mg / L, the dosage of sewage treatment agent is 2kg / ton of sewage; When the water ammonia nitrogen is less than 50mg / L, the dosage of sewage treatment agent is 1kg / ton of sewage.

Embodiment 3

[0028] The sewage treatment agent specially used for high ammonia nitrogen content in this embodiment is composed of the following raw materials in parts by weight: 3 parts of zeolite powder, 1.2 parts of persimmon tannin, 2.4 parts of diatomaceous earth and 0.3 part of grape seed tannin.

[0029] When the influent ammonia nitrogen>100mg / L, the dosage of sewage treatment agent is 2.2kg / ton of sewage; when 50mg / L≤influent ammonia nitrogen≤100mg / L, the dosage of sewage treatment agent is 1.5kg / ton of sewage; When the influent ammonia nitrogen is less than 50mg / L, the dosage of sewage treatment agent is 0.8kg / ton of sewage.

Abstract

The invention belongs to the technical field of sewage treatment, and discloses a treating agent special for sewage high in ammonia and nitrogen content, aiming at solving the problem of low nitrogentreating capacity of existing sewage treating agent. The treating agent contains the following materials in parts by weight: 2-5 parts of zeolite powder, 1-1.5 parts of persimmon tannin, 2-3 parts ofkieselguhr, and 0.2-0.5 part of grape seed tannin. Due to improved curing capacity, the treating agent disclosed by the invention can improve the treating capacity for ammonia and nitrogen.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment agent specially used for high ammonia nitrogen content. Background technique [0002] With industrial progress and social development, water pollution is becoming more and more serious, becoming the number one environmental governance problem. China's water quality and water shortage are becoming more and more serious. Water pollution affects industrial production, increases equipment corrosion, affects product quality, and even makes production impossible. If it continues, water pollution will affect people's lives, destroy ecology, directly endanger people's health, and cause great damage. [0003] Nitrogen is a very important pollution factor in the water environment. With the development of industries such as petroleum, food and pharmaceuticals and the improvement of people's living standards, the concentration of nitrogen in urban sewa...
