Efficient glass fiber reinforced plastic septic tank structure for domestic sewage treatment

Abstract

The invention discloses an efficient glass fiber reinforced plastic septic tank structure for domestic sewage treatment in the technical field of septic tanks, which comprises a body, a first partition plate, a second partition plate, a primary corruption tank, a deep corruption tank, a clarification tank, a water inlet, a water outlet, a first overflow port, a second overflow port, a stand column, a floating plate and a surge bin, wherein the surge bin is provided with an overflow hole, a baffle is slidably connected into the primary corruption tank and driven by a driving unit to move synchronously with the surge bin. After sewage flows into the primary corruption tank from the water inlet, the sewage flows into the surge bin, so that the process that the sewage flows into the primary corruption tank is buffered, and the phenomenon that solid sediments deposited in the primary corruption tank are stirred, and consequently the sewage treatment capacity is affected is avoided. When the surge bin ascends and descends along with the liquid level, the baffle can synchronously lift, so that the opening height of the first overflow port is automatically adjusted, and the sewage inflow speed is matched with the speed of the sewage flowing into the deep corruption tank.

Description

technical field [0001] The invention relates to the technical field of septic tanks, in particular to a high-efficiency fiberglass septic tank structure for domestic sewage treatment. Background technique [0002] FRP septic tank refers to the equipment specially used to treat domestic sewage made of synthetic resin as the matrix and glass fiber reinforced material. FRP septic tank is a composite material product actively promoted by the country. It is light in weight, high in strength, and tough. Good quality, corrosion resistance, bright colors, mirror finish and other advantages, have far exceeded the similar products of ceramics, hard plastic, steel and other materials. The solid content in the discharged sewage, the FRP septic tank is mainly suitable for the purification of domestic sewage in civil buildings such as industrial enterprise living areas and urban residential quarters, and is also widely used in chemical, petroleum, construction, textile, aviation, navigati...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, after the sewage flows into the primary septic tank, the upper layer of clear water flows into the deep septic tank through the conduit (referred to as the first overflow in this application), while the solid waste in the lower layer will be deposited at the bottom of the primary septic tank, but when the sewage flows into If the speed is too fast, the liquid level of the sewage in the primary septic tank rises rapidly, which in turn causes the sewage to flow out of the conduit quickly, making it impossible for the sewage to be effectively deposited, or the solid waste in the sewage flows into the deep septic tank without being deposited, causing The sedimentation effect of the primary corrosion tank is reduced. In addition, when the sewage flows into the primary corrosion tank, it will agitate the solids that have been deposited in the primary corrosion tank, which in turn affects the sewage treatment capacity of the primary corrosion tank.
