Problems solved by technology

[0003] Aiming at the problems of high unit investment and operation cost, complex management, operation and maintenance, and poor impact load resistance existing in the existing sewage treatment process of small and medium-sized towns, the present invention proposes a new sewage treatment process. The core of the process is to adopt (TF) two-stage "Physical-chemical-biochemical" enhanced treatment process for efficient treatment of sewage

specific Embodiment approach 1

[0017] Among them, you can choose not to add the front-end of the first-stage micro-membrane enhanced filtration process and the front-end of the second-stage biochemical filtration, and add metal aluminum salt agents, iron salts, and polymer agents separately or separately.

[0018] The one-stage micro-membrane enhanced filtration process can remove 60%-80% of suspended solids, 40-50% of COD, and BOD 5 20-40%, and the removal rate of total phosphorus reaches more than 20-90%. At the same time, the micro-membrane filter also replaces the traditional sludge dewatering machine, directly dehydrates the generated sludge, realizes the integrated treatment of sewage and sludge, and saves the process of grit chamber, primary sedimentation tank, secondary sedimentation tank, sludge dehydration room, etc. , greatly reducing the project cost, floor area and operating costs.

[0019] The secondary biochemical filtration process uses a biological filter treatment process, including the...

Abstract

The invention relates to a novel sewage treatment technology which is a TF unit combination sewage treatment technology. Aiming at problems of high unit investment, high operating cost, complex management, operation and maintenance, and weak anti-shock loading capability in current sewage treatment technology in middle and small cities, the invention provides a novel sewage treatment technology, which employs a two-stage (TF) physicochemical-biochemical enhanced treatment technology as a core technology to treat sewage efficiently. The TF technology is a simple technology with low construction costs, low operation costs, and is easy for control and management and suitable for sewage treatment plants in cold regions and sewage treatment plants with high shock loads, wherein the equipment of the technology occupy small land. In addition, employing a unit combination method, a treatment scale can reach 1000t / d-50000t / d, and treated water quality, according to requirements, can meet standards of Grade one A, Grade one B or reuse water.

Description

Technical field: [0001] The invention relates to a new sewage treatment process. Background technique: [0002] There are many small and medium-sized cities and towns in my country, with a wide distribution area and a large amount of sewage discharge. At the same time, the investment and operation costs of small and medium-scale sewage treatment plants are very high, especially 2*10 4 m 3 For sewage treatment plants below / d, the unit investment cost and operating cost are high, and the situation is even more serious in the low temperature season in the cold northern regions. At present, my country lacks high-efficiency and low-consumption treatment technologies suitable for national conditions for the large-scale and wide-ranging sewage problems in small and medium-sized cities and towns. With the rapid development of the construction of small towns, the water quality pollution in various river basins has further deteriorated, and the scale of sewage plants in small towns...
